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

Tukey HSD
(I) VAR00002	(J) VAR00002	Mean Difference (I-J)	Std. Error	Sig.	95% Confidence Interval
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 the obtained statistical value and the critical value?
3. Is it significant, how do you know?
4. Do I reject the null?
5. Write the sentence and the APA statistics format for these results.
