This calculator uses a two-sample t test, which compares two datasets to see if their means are statistically different.

When entering raw data, the t test calculator will run the Shapiro-Wilk normality test and calculate outliers, as part of the test calculation, and will generate the R code for your data. ... Target: To check if the difference between the average (mean) of two groups (populations) is significant, using sample data Example1: A man of average is expected to be 10cm taller than a woman of average (d=10) Example2: The average weight of an apple grown in field 1 is expected to be equal in weight to the average apple grown in field 2 (d=0)
