Question

An educational psychologist wants to know if length of time and type of training affect learning simple fractions. Fifth graders were randomly selected and assigned to different times (from 1 to 3 hours) and different teaching conditions (old method vs. meaningful method). All students were then tested on the "fractions" subtest of a standard arithmetic test. What can the psychologist conclude with α = 0.05?

	Time
Train	one hr	two hrs	three hrs
old	5 6 7	6 3 7	8 9 10
meaningful	6 7 8	9 10 11	7 9 10

A) Input the appropriate value(s) to make a decision about H₀.
Train: p-value =
Time: p-value =
Interaction: p-value =

B) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
Train: η² =
Time: η² =
Interaction: η² =

C) Make an interpretation based on the results.

There is a training difference in learning fractions.

There is no training difference in learning factions.
