Answer 1

INDEPENDENT SAMPLE

Question 2

when the individual selected to be in one
sample are used to determine the individuals to be in the second sample

Answer 2

DEPENDENT SAMPLE

Question 3

compares the means of two related groups
to determine whether there is a statistically
significant difference between these
means

WILCOXON-SIGNED RANK TEST

Question 5

It is used to test whether population means
are significantly different from each other,
using the means from randomly drawn
samples.

Answer 5
