Question

my 20 pts Question 3 Four groups of college students underwent a sleep deprivation study. There were 6 participants per condition. They had been deprived of sleep for 0,6, 12, or 24 hours. Afterwards, a memory test was given. An ANOVA was conducted in Microsoft Excel and the results are given in the table below. Follow-up this ANOVA with a post hoc test (-01) to determine which groups differed. Construct a table of mean differences to organize the means. Make certain to explain the results.

Answer 1

Mean difference

G1-G2= 1

G1-G3=4.1666

G1-G4=5.3333

G2-G3=3.1666

G2-G4=4.3333

G3-G4=1.1667

HSD= (q alpha,K,N-K)*Sqrt(MSE/n)=0.3841

Here all |Group difference|>HSD So all means are difer
