Deck 23: Dependent Samples T-Test

Question 1

Which of the following is NOT true about Dependent Samples t Test?

A) The sample groups are related
B) Compares two means from one sample
C) It is a within-subject design
D) It does not control for any pre-existing individual differences

Answer 1

D

Question 2

Which if the following is a disadvantage of Dependent Samples t Test?

A) One sample
B) Repeated test may show improvement due to practice
C) Two samples
D) Normal distribution of the data

Answer 2

B

Question 3

the matching or paired participants in the depended groups has already built in a similarity between the groups or repeated data points making it possible to increase error.

Answer 3

False

Question 4

If the probability that a particular t value have occurred by chance is .000 in a Dependent Samples t Test, what can you conclude?

A) The p value is too low to reject the null hypothesis
B) There is a significant difference between the two means
C) There is not a difference between the two means
D) The p value is too low for the null hypothesis to be true

Question 5

If the results indicate that a paired samples analysis produced a significant t value [t (19) = 9..967, p < .001] what is the likelihood that the null hypothesis is true?

A) Less than 1 in 1000
B) Less than 1 in 100
C) Less than 1%
D) Less than .001%

Question 6

What is particular about the results from a significant nondirectional hypothesis test?

A) The one mean is greater than the other mean
B) The one mean is less than the other mean
C) That the two means are statistically different
D) The difference between the two means is zero
