Original research, also called primary research, is research that is not exclusively based on a summary, review, or synthesis of earlier publications on the subject of research.This material is of a primary-source character. In fact, it is a search for broader meaning of research findings. Cost reduction may not be as sexy as data profit, but as Intel proves, it is a benefit of data analysis that should not be neglected. Indeed, if several departments have different approaches to interpret the same data, while sharing the same goals, some mismatched objectives can result. image University of Wisconsin-Madison Space Science and Engineering Center, Absorption, Distribution, and Storage of Chemicals, Y-Chromsome and Mitochondrial DNA Haplotypes, Solutions, Solubility, and Colligative Properties, Plates, Plate Boundaries, and Driving Forces, Scientific Notation and Order of Magnitude, Understanding Scientific Journals and Articles, Data collection, analysis, and interpretation: Weather and climate, Data analysis: A complex and challenging process, Data interpretation: Uncovering and explaining trends in the data, Different interpretations in the scientific community, Debate over data interpretation spurs further research, Technology for sharing data advances science, Intergovernmental Panel on Climate Change. Defining uniform data collection standards was an important step in producing a truly global dataset of meteorological information, allowing data collected by many different people in different parts of the world to be gathered together into a single database. It is difficult to grow and make dependable improvements without, at the very least, minimal data collection and interpretation. Reporting error and uncertainty for data does not imply that the measurements are wrong or faulty in fact, just the opposite is true. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Data Interpretation questions are grouped together and refer to the same table, graph or other data presentation. In neither case can one simply look at the table of numbers and observations and answer the question which route to take, or how global climate has changed. Find out how with our guide. Yet, without proper research and analysis, an idea is likely to remain in a stagnant state forever (i.e., minimal growth). Based on the agreement between these multiple datasets, the team of contributing scientists wrote: Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level. Related to the notion of connected and blended data is that of mobile data. If you continue browsing the site, you agree to the use of cookies on this website. For example, in 1997, the Collaborative Group on Hormonal Factors in Breast Cancer published a widely-publicized study in the prestigious medical journal The Lancet entitled, "Breast cancer and hormone replacement therapy: collaborative reanalysis of data from 51 epidemiological studies of 52,705 women with breast cancer and 108,411 women without breast cancer" (Collaborative Group on Hormonal Factors in Breast Cancer, 1997). Data analysis and interpretation is the process of assigning meaning to the collected information and determining the conclusions, significance, and implications of the findings. Now consider that over huge expanses of the ocean, where no consistent measurements are available. Because of their differences, it is important to understand how dashboards can be implemented to bridge the quantitative and qualitative information gap. Found insideThe Index, Readers Guide themes, and Cross-References combine to provide robust search-and-browse in the e-version. Remedy: attempt to eliminate the variable you believe to be causing the phenomenon. The weather has long been a subject of widespread data collection, analysis, and interpretation. This type of broad synthesis of data and interpretation is critical to the process of science, highlighting how individual scientists build on the work of others and potentially inspiring collaboration for further research between scientists in different disciplines. Lets quickly review the most common statistical terms: Typically, quantitative data is measured by visually presenting correlation tests between two or more variables of significance. This guide to the essentials of doing participatory methods in a broad range of health contexts covers all of the stages of the research process, from research design right through to dissemination. Qualitative analysis: observe, document and interview notice, collect and think about things. Typically, narrative data is gathered by employing a wide variety of person-to-person techniques. Based on the smoothed curves, Jones, Wigley, and Wright interpreted their data to show a long-term warming trend. One could simply take an average of all of the available measurements for a single day to get a global air temperature average for that day, but that number would not take into account the natural variability within and uneven distribution of those measurements. The possible link between breast cancer and hormone replacement therapy (HRT) had been studied for years, with mixed results: Some scientists suggested a small increase of cancer risk associated with HRT as early as 1981 (Brinton et al., 1981), but later research suggested no increased risk (Kaufman et al., 1984). (1981). (1997). By using historic and current data, Intel now avoids testing each chip 19,000 times by focusing on specific and individual chip tests. 8. Responsible Conduct of Research, now in a completely updated second edition, provides an introduction to the social, ethical, and legal issues facing scientists today. Qualitative data analysis can be summed up in one word categorical. It occurs over the course of a day, a year, or many years, and may involve one or many scientists whose priorities change over time. Lindzen, R. S. (1990). In analyzing and interpreting data, point out those that are consistent or inconsistent with the theory presented in the studys theoretical framework. research and related services. Data (the plural form of the word datum) are scientific observations and measurements that, once analyzed and interpreted, can be developed into evidence to address a question. With todays pace of innovation, it is no longer feasible (nor desirable) to have bulk data centrally located. This second edition of Quantitative Methods for Health Research: A Practical Interactive Guide to Epidemiology and Statistics also helps develop critical skills that will prepare students to move on to more advanced and specialized methods. CENTRE FOR ADVANCED STUDIES IN EARTH Data sources: The research example used is a multiple case study that explored the role of the clinical skills laboratory in preparing students for the real world of practice. Sampling data and data collection in qualitative research January 2013 In book: Nursing & Midwifery Research: Methods and Appraisal for Evidence-Based Practice (pp.123-140) The task of interpretation has two major aspects viz., the effort to establish continuity in research through linking the results of a given study with those of another, and the establishment of some explanation concepts. Figure 3 shows a lot of variability in the data: There are a number of spikes and dips in global temperature throughout the period examined. Looks like youve clipped this slide to already. Whether you want to measure customer trends or organizational performance, you now have the capability to do both without the need for a singular selection. Were going to review the most commonly used charts and graphs in Excel/PowerPoint. The book is organised according to the following thematic sections: Part I: Overview of Qualitative Research Part II: Philosophical Perspectives Part III: Qualitative Research Methods Part IV: Modes of Analyzing and Interpreting It brings together both qualitative and quantitative data knowledgeably analyzed and visualizes it in a meaningful way that everyone can understand, thus empowering any viewer to interpret it: Data analysis and interpretation are critical to develop sound conclusions and make better informed decisions. The insights obtained from market and consumer data analyses have the ability to set trends for peers within similar market segments. Studies have shownthat companies in the top third of their industries are, on average, 5% more productive and 6% more profitable when implementing informed data decision-making processes. We are supported by The National Science Foundation and the U.S. Department of Education. The volume is organized into four sections. Section I provides a rationale for this volume; namely, that including visual displays in research and testing can enhance comprehension and processing efficiency. By Mona Lebied in Data Analysis, Aug 22nd 2018. For example, in theology, Biblical hermeneutics concerns the general principles for the proper interpretation of the Bible. Anne E. Egger, Ph.D., Anthony Carpi, Ph.D. Data Analysis and Interpretation Visionlearning Vol. Base your interpretations in your research. RESEARCH DATA BY The weather forecast that helped you decide what to wear, for example, was an interpretation made by a meteorologist who analyzed data collected by satellites. If quantitative data interpretation could be summed up in one word (and it really cant) that word would be numerical. There are few certainties when it comes to data analysis, but you can be sure that if the research you are engaging in has no numbers involved, it is not quantitative research. In other words some computation has taken place that provides some understanding of what the data means. Interpretation refers to the task of drawing inferences from the collected facts after an analytical and or experimental study. When scientists begin to interpret their data, they draw on their personal and collective knowledge, often talking over results with a colleague across the hall or on another continent. This book explores ways to adapt research methods from other disciplines to the special education context and provides the reader with a framework for critically analyzing and conducting research in areas where people with disabilities live In 1990, Richard Lindzen, a meteorologist at the Massachusetts Institute of Technology, published a paper expressing his concerns with the warming interpretation (Lindzen, 1990). Make the link between the data and your interpretations clear. Shrewd and insightful, the collection will be required reading for students of the latest thinking on research methods. Here, you see the year as the category and the number of births as the numerical count. Written in a humorous and encouraging style, this text shows how the most common statistical tools can be used to answer interesting real-world questions, presented as mysteries to be solved. Consider the range of temperatures around the world on any given day in January (see Figure 2): In Johannesburg, South Africa, where it is summer, the air temperature can reach 35 C (95 F), and in Fairbanks, Alaska at that same time of year, it is the middle of winter and air temperatures might be -35 C (-31 F). It involves the interpretation of data gathered through the use of analytical and logical reasoning to determine patterns, relationships or trends. In addition, making data easily accessible helps promote interdisciplinary research by opening the doors to exploration by diverse scientists in many fields. Different processes can be used together or separately, and comparisons can be made to ultimately arrive at a conclusion. Mann, Bradley, and Hughes used many of the same analysis techniques as Jones and co-authors, such as applying a ten-year running average, and in addition, they included measurement uncertainty on their graph: the gray region shown on the graph in Figure 4. Perhaps you think, "It's summer, so it's usually warm." When industry trends are identified, they can then serve a greater industry purpose. Informed decision making has a tendency to be cyclical. interpretation to aid in the appraisal of nursing research. Extensive examples throughout the book highlight the techniques and theory described, and provide the inspiration for readers to generate ideas for new research projects. The book is directly focused on tourism and leisure examples. Hereafter is a list-summary of how to interpret data and some tips: The importance of data interpretation is undeniable. Modernonline data visualization toolsprovide a variety of color and filter patterns, encourage user interaction and are engineered to help enhance future trend predictability.

For example, the authors note: Early SSTs [sea surface temperatures] were measured using water collected in uninsulated, canvas buckets, while more recent data come either from insulated bucket or cooling water intake measurements, with the latter considered to be 0.3-0.7 C warmer than uninsulated bucket measurements. Introducing Research and Data in Psychology shows how research design and data analysis are attainable and useful skills. The authors therefore applied a correction for ship size in their data. Historical air temperature measurements over the ocean were taken aboard ships, but the type and size of ship could affect the measurement because size "determines the height at which observations were taken." Take a step back: and think about your data from various perspectives, and what it means for various participants or actors of the project. Collect your data and make it as clean as possible. Can we understand why this is happening by looking at other program indicators? Project management dashboards will make your business more efficient, cohesive, and successful. Today, mobile analysis applications seamlessly integrate with everyday business tools. Data analysis summarizes collected data. You can change your ad preferences anytime. Digital age example:your boss asks you to analyze the success of a recent multi-platform social media marketing campaign. A bestseller in its First Edition, this invaluable book presents an innovative approach to the components of design and how they interact with each other. Jones, P. D., Wigley, T. M. L., & Wright, P. B. Sign up for a Scribd free trial to download now. The two main ways of summarizing data are by using tables and charts or graphs. Make visible the assumptions and beliefs, or mental models, that influence your interpretation. Examples The magnitude of the error describes how confident the scientists are in the accuracy of the data, so bigger reported errors indicate less confidence (see our Uncertainty, Error, and Confidence module). It is the raw information from which statistics are created. Statistical techniques such as averaging are commonly used in the research process and can help identify trends and relationships within and between datasets (see our Statistics in Science module). For social researchers who need to know what procedures to use under what circumstances in practical research projects, this book does not require an indepth understanding of statistical theory. Global-scale temperature patterns and climate forcing over the past six centuries. A pie chart displays the contribution of each value to the total. Finally, Lindzen suggested that the interpretation of the global mean temperature data is inappropriate, and that there is no trend in the data. The early international cooperation and investment in weather-related data collection has produced a valuable long-term record of air temperature that goes back to the 1850s. From businesses, to newlyweds researching their first home, data collection and interpretation provides limitless benefits for a wide range of institutions and individuals. Once scales of measurement have been selected, it is time to select which of the two broad interpretation processes will best suit your data needs. As a digital age solution, they combine the best of the past and the present to allow for informed decision makingwith maximum data interpretation ROI. A higher level of data interpretation involves determining the reason for the temperature increases. This handbook focuses on the often neglected dimension of interpretation in educational research. The SlideShare family just got bigger. The critique of qualitative research requires the use of different standards and criteria than are used for quantitative research. A line graph should be used to display trends over time. Packed with detailed examples, a glossary, further reading lists and a section on writing up, this book is exactly what you need to get you started in qualitative research. First, he argued that the data collection was inadequate, suggesting that the current network of data collection stations was not sufficient to correct for the uncertainty inherent in data with so much natural variability (consider how different the weather is in Antarctica and the Sahara Desert on any given day). Anyone can apply to use the instruments as long as they provide IRIS with the data they collect during their seismic experiments. Cancer, 47(10), 2517-2522. Reflect on your own thinking and reasoning: and be aware of the many pitfalls data analysis and interpretation carries. It is the simplest and most common use of data in business today. Business dashboardsare the digital age tools for big data. In describing why the reanalysis was used, the authors write: The increase in the relative risk of breast cancer associated with each year of [HRT] use in current and recent users is small, so inevitably some studies would, by chance alone, show significant associations and others would not. They do not go further in their interpretation to suggest possible causes for the temperature increase, however, but merely state that the results are "extremely interesting when viewed in the light of recent ideas of the causes of climate change.". 3) Visualization. These standards provided guidelines for data collections and recording that assured consistency within the dataset. It can be challenging to see trends in data that have so much variability; our eyes are drawn to the extreme values in the jagged lines like the large spike in temperature around 1876 or the significant dip around 1918. Data analysis is the most crucial part of any research. In these instances, it may be necessary to conduct further research. Data gathering and interpretation processes can allow for industry-wide climate prediction and result in greater revenue streams across the market. Of course, they were not able to use air temperature readings from thermometers to extend the record back to 1000 CE; instead, the authors used data from other sources that could provide information about air temperature to reconstruct past climate, like tree ring width, ice core data, and coral growth records (Figure 4, blue line). 1) Informed decision-making:A decision is only as good as the knowledge that formed it. The task of interpretation has two major aspects viz., Capable of displaying key performance indicators (KPIs) for both quantitative and qualitative data analyses, they are ideal for making the fast-paced and data-driven market decisions that push todays industry leaders to sustainable success.
