Discuss why it is important to summarize what a study’s data contain before trying to analyze if the sample is representative and our hypothesis supported.
What will be an ideal response?
Ans: Answers vary
It can be difficult to interpret what data reveal about behavior from just the raw data (i.e., the scores from each participant). Thus, researchers rarely report the raw data they have collected. Instead, researchers typically report descriptive statistics that summarize the set of data (also called a distribution). There are three main categories of descriptive statistics that help researchers summarize data. They are (1) the central tendency of the distribution, (2) the variability in the distribution, and (3) graphs or tables of the central tendency and variability. The central tendency and variability will be useful measures in hypothesis testing.
