These files are related to t-test application in two groups of people. The aim is to find if the age is equivalent between them. For this reason, the t-test is used. Before the t-test application is important to know whether the samples of the groups follow a normal distribution.
We have a file in R language named 2-groups-t-test-analysis.R
that load the CSV file named participants-sample.csv
, then it calculates a histogram and a QQ-plot for the 2 groups, calculates the Shapiro Wilk for the normality, and calculates the t-test.
