WebThe function ttest_ind () takes two samples of same size and produces a tuple of t-statistic and p-value. Example Find if the given values v1 and v2 are from same distribution: import … WebCalculate the t-test on TWO RELATED samples of scores, a and b. This is a test for the null hypothesis that two related or repeated samples have identical average (expected) values. Parameters: a, barray_like The arrays must have the same shape. axisint or None, default: 0 If an int, the axis of the input along which to compute the statistic.
