Given the results from a one-way ANOVA: F(3,40)=1.02, p>.05

a) How many groups were compare?

b)What was the sample size?

c) What was alpha?

d) What was the critical value?

e) Did the researcher conclude the difference was statistically significant?

Solution

Degrees of freedom between = k - 1
Degrees of freedom Within = n - k

Degrees of freedom Total F( k-1,n - k,) at 0.05 is = F(3,40)=1.02, p> 0.05

a) How many groups were compare? k-1 = 3 => k = 4
b) What was the sample size ? T = 3+40 = 43
c) What was alpha? it is 0.05
d) What was the critical value? 1.02
e) F(3,40)=1.02, p>.05,Value of P> 0.5 and Here Do n\'t Reject Ho
