1. I am interested in knowing if the type of lighting in a classroom makes a difference on how well a student can remember. I put 15 of 45 students into 1 of 3 groups based on chance: Group 1 has the lights off, Group 2 has fluorescent lighting and Group 3 has LED lighting. I then analyzed the data and came out with the following:

ANOVA
VAR00001
	Sum of Squares	Df	Mean Square	F	Sig.
Between Groups	788.844	2	394.422	13.857	.000
Within Groups	1195.467	42	28.463
Total	1984.311	44

Multiple Comparisons

Lower Bound	Upper Bound
1.00	2.00	-1.86667	1.94811	.607	-6.5996	2.8663
3.00	-9.66667*	1.94811	.000	-14.3996	-4.9337
2.00	1.00	1.86667	1.94811	.607	-2.8663	6.5996
3.00	-7.80000*	1.94811	.001	-12.5329	-3.0671
3.00	1.00	9.66667*	1.94811	.000	4.9337	14.3996
2.00	7.80000*	1.94811	.001	3.0671	12.5329
*. The mean difference is significant at the 0.05 level.

1.What type of test and why did I choose this specific test? Answer here Check your assumptions to be sure that you can use this statistic!

1. Write the Null and alternative hypotheses:
2. What is my obtained statistical value and my critical value?
3. Is it significant, how do you know?
4. Do I reject the null?
5. Write the sentence and APA statistics format for these results. Write In APA format statistically
