Tukey HSD
(I) Color	(J) Color	Mean Difference (I-J)	Std. Error	Sig.	95% Confidence Interval
					Lower Bound	Upper Bound
Blue	Green	35.200*	1.661	.000	31.08	39.32
	Yellow	20.700*	1.661	.000	16.58	24.82

Problem Set 4.7: Tukey HSD Interpretation

• Criterion: Interpret Tukey HSD results from SPSS output.
• Data: Use your output from Problem Set 4.10.
• Instruction: Identify where significant differences exist at the .05 level between your colors. (Hint, there are a total of 3 things you should be reporting)

Answer 1

For Blue & Green:

The p-value from the output is 0.000.

The mean difference is significant at the 0.05 level.

For Blue & Yellow:

The p-value from the output is 0.000.

The mean difference is significant at the 0.05 level.

For Yellow & Green:

The p-value from the output is 0.000.

The mean difference is significant at the 0.05 level.
