In the morning, after having had nothing to eat since the night before, 75 participants were randomly assigned to one of three groups (25 in each group): Those who were fed a large meal, those who were fed a small meal, and those who were fed nothing. Then all participants were given a memory test. The results were as follows:
Memory Test Scores:
Large Meal Small Meal Nothing
Mean 2.1 2.5 2.9
S2 1.0 1.2 .8
Based on these results, does size of breakfast affect memory? Do a one-way ANOVA (Use the .05 level.)What is S2?
In the experiment above, what is S2?
In the experiment above, what is F ?
In the experiment above, what is d f ?
In the experiment above, what is the cutoff score (use the closest value for the denominator df)?
