Question

You do a study comparing the vertical jump abilities of soccer players vs volleyball players. What type of t-test should you use?

A) Dependent t-test

B) Independent t-test

C) One-sample t-test

Answer 1

Solution:

Given: You do a study comparing the vertical jump abilities of soccer players vs volleyball players.

So here we have two different samples soccer players and volleyball players .

We have to compare the vertical jump abilities of soccer players and volleyball players.

Thus we have two independent samples.

Thus correct option is:

B) Independent t-test

For dependent t-test we need pairs of observation taken on same object, but here we have observations of two different objects. Thus dependent t test is not useful for this test.

As we have two samples, one sample t test can not be used.
