Descriiptive statistics are just what they sound like, statistics that allow you to describe or summarize the data with regard to such things as their distribution and their spread. Descriiptive statistics provide you with a picture of your data while inferential statistics (which we will discuss in subsequent assessments) allow you to draw conclusions about relationships between variables or differences between groups.
A solid understanding of descriiptive statistics is foundational to grasping the concepts presented in inferential statistics. This assessment measures your understanding of key elements of descriiptive statistics.
Your first statistical software assessment includes two sections in which you will do the following:
Create two histograms.
Calculate measures of central tendency and dispersion.
This will give you some experience with the data set.
