Sample 1: 10.43, 9.95, 10.19, 10.89, 9.98, 7.52, 9.8, 10.91, 10.71, 11.2

Sample2: 11.01, 11.02, 10.39, 12.1, 12.33, 11.94, 10.92, 11.43, 12.79, 13.32

Input

Samples

Select a column of data for Sample 1 and Sample 2.

Once selected, the mean is calculated and shown the right of the menu.

NOTE: The columns do not need to be equal in length but entries are omitted when they are not paired in a given row.

Thus, 9.8 in Sample 1 and 12.1 in Sample 2 are omitted from the test. As a result, the mean of the entire column does not match the mean shown on the t-test.
