Question

Conduct a paired-samples (repeated measures) t test using the following data:

The Dark Souls video game series has achieved meme-status as being controller-breaking difficult. A researcher was interested in how frustrating playing the games can be so she asked participants to rate their base frustration levels and then had them play the first game in the series – Dark Souls – as its seen as one of the harder games. The data is as follows:

Participant	Before	After
A	6	11
B	5	10
C	4	12
D	1	9
E	2	12
F	3	8
G	4	9
H	5	11

.1) Determine the values necessary to calculate the t statistic.

Type in the Sample Mean, Population Mean, and Standard Error. Please label which number is which.

Answer 1

x:- base frustration levels before playing game

y:- base frustration levels after playing game

d = difference in base frustration levels after & before playing the game.

d = y - x

x	y	d	d^2
6	11	5	25
5	10	5	25
4	12	8	64
1	9	8	64
2	12	10	100
3	8	5	25
4	9	5	25
5	11	6	36
SUM		52	364
