Deck 21: Introduction to the T-Test

Question 1

the researcher uses a t test when comparing two means to determine statistical significance.

Answer 1

True

Question 2

When comparing two means which is the null hypothesis?

A) There is no true difference between men and women
B) There is a true difference between men and women
C) The difference is not due to the sampling error

Answer 2

A

Question 3

When should the researcher reject the null hypothesis?

A) When the probability that the null hypothesis is correct is .05 or less
B) When the probability that the null hypothesis is correct is .05 or higher

Answer 3

A

Question 4

Which of the factors does not determine the probability level of rejecting the null hypothesis?

A) Larger samples
B) Larger observed difference between the two means being compared
C) The smaller variance among participants
D) The smaller observed difference between the two means being compared

Question 5

the larger the samples, the less likely that the difference between two means was created by sampling errors.

Question 6

The smaller the observed difference between the two means the more likely that the difference was created by sampling errors.

Question 7

The larger the variance among the participants, the less likely the difference between two means was created by sampling errors.
