Question

EXPERIMENT TWO

Dr. Marek wants to replicate the previous study. She selects a different sample of children who regularly play video games and those who do not and obtains the following attention-span data:

Video	No Video
20	16
19	20
31	24
18	21
24	27
27	21
31	23
23	21
25	16
23	22

	Video	No Video
M (Experiment 2)	24.1	21.1
SD (Experiment 2)	4.56	3.35

7.Using SPSS compute the appropriate test. Paste SPSS output here.

With alpha set at .05, write a conclusion of the findings.

Be sure to report the appropriate statistic in APA style.   

Answer 1

H0: There is no significance difference between the means of Video and No video
H1: There is significance difference between the means of Video and No video
Let the los be alpha = 5%

The SPSS output be

P-value of test of equal variance is 0.320 > alpha 0.05 so we accept H0

thus variance of two populations are equal

P-value of test of means is 0.149 > alpha 0.05 so we accept H0

Thus the two groups means are equal i.e. there is no significance difference between the means of Video and No video
