# T-TEST

Assignment 2: RA 1: t-Tests
Working with Data in Microsoft Excel
Once again, reading about t-test statistics and descriptive statistics is one thing. Actually using software to compute them requires different skill sets. This assignment is designed to give you the opportunity to practice using Microsoft Excel to compute a t-test and to reinforce your learning of computing descriptive statistics from a previous module. A data set has been presented below for you to use to conduct your analyses. The data set represents the scores from five students who were tested on the same material using three different forms of the test.
