Question

1. Name the 2 parametric tests used for 2 independent samples

2. Name the nonparametric test used for 2 independent samples.

Answer 1

a)2 parametric tests used for 2 independent samples

1)Welch's t test (For unequal population variance)

2)Two sample Fisher's t test (For equal population variance assumption )

b)Two non parametric tests used for two independent samples are

1)Mann-Whitney's test..(to determine if the samples come from a single population or from two different populations meaning that the two samples may be considered identical or not.)

2)Kolmogorov-Smirnov's test(to determine if the populations from which the samples were taken have different cumulative distribution functions. )
