The One-Way ANOVA applet lets you see how the F statistic and the P-value depend on the variability of the data within groups, the sample size, and the differences among the means. (a) The black dots are at the means of the three groups. Move these up and down until you get a configuration that gives a P-value of about 0.01. What is the value of the F statistic? This answer has not been graded yet. (b) Now increase the variation within the groups by sliding the standard deviation bar to the right. Describe what happens to the F statistic and the P-value. This answer has not been graded yet. (c) Using between- and within-group variation, explain why the F statistic and P-value change in this way. This answer has not been graded yet.

Between groups One way ANOVA
A researcher wants to see expand on the study that looks at
music’s effect on studying. She has three groups and has each group
listen to different genres. All groups are studying a list of words
while listening to music and then write down how many words they
remember. She collects the following data:
Group listening to Run The Jewels:
7, 9, 7, 5, 6, 5, 8
Group listening to Arctic Monkeys:
7, 5, 4,...

(b)The among group mean square increases.
(c)The within group sum or squares
decreases.
(d)The within group mean square decreases.
