A researcher conducts a ONEWAY ANOVA with 4 groups. The critical value of F is 4.6. The researcher calculates a value of F from the data of 3.2, which has an associated p value of .14. This means:

a. at least one of the groups is different from the other groups.

b. none of the answers are correct

c. the researcher needs to do a posthoc test

d. there is a 14% chance the data are in the null distribution

    In a one-way ANOVA, if the computed F statistic exceeds the critical F value, we should reject H0 since there is evidence that all the means differ reject H0 since there is evidence that at least one of the means is different from the others not reject H0 since there is no evidence of a difference in means not reject H0 because a mistake has been made.

(Select all that apply) The larger the variability within groups relative to the variability between groups, the larger the F test statistic tends to be. The results of the ANOVA F test does not tel us which groups are different or how different they are. An F-distribution is symmetrical about 0 and extends indefinitely in both directions In a one-way ANOVA, if the null hypothesis is rejected, we conclude that the population means...
