Which of the following makes data analysis easier? a. identifying contrasting objects or events b. listing characteristics of contrasting objects or events c. researching information about contrasting objects or events d. organizing contrasting observations into a table, chart, or graph
Among the essential stages of epidemiological research, one of the most important is the identification of data with which the researcher is working, as well as a clear and synthetic description of these data using graphs and tables. The identification of the type of data has an impact on the different stages of the research process, encompassing the research planning and the production/publication of its results. For example, the use of a certain type of data impacts the amount of time it will take to collect the desired information (throughout the field work) and the selection of the most appropriate statistical tests for data analysis.
On the other hand, the preparation of tables and graphs is a crucial tool in the analysis and production/publication of results, given that it organizes the collected information in a clear and summarized fashion. The correct preparation of tables allows researchers to present information about tens or hundreds of individuals efficiently and with significant visual appeal, making the results more easily understandable and thus more attractive to the users of the produced information. Therefore, it is very important for the authors of scientific articles to master the preparation of tables and graphs, which requires previous knowledge of data characteristics and the ability of identifying which type of table or graph is the most appropriate for the situation of interest.
d. Organizing contrasting observations into a table, chart, or graph.
A data in research represents the material which is obtained after scientific research, this material is necessary to validate research findings. A data can be measured, collected, reported and analysed in order to derive appropriate result of research process. A data can be in the form of charts, graphs, or image. To derive a conclusive result one or more observations are compared, the differences and similarities of these observations can be analysed by utilizing data in a correct format of comparison which can make analysis easier. Therefore, organizing contrasting observations into a table, chart, or graph makes data analysis easier.
d. Organizing contrasting observations into a table, chart, or graph
The answer is D.
When we do an experiment, we need to somehow find out if one variable is affecting the others. In order to make the analysis easier, it's better to put the contracting observations such as range of effect/period into table, chart and graph so we know what variable caused the most effect
hope this helps
