One of the measures is the Individual Assessment Profile Several studies have been conducted on the instrument, and reliability estimates for items, using internal consistency (alpha), ranged from 0 to 99. A second instrument is the Recovery Altitude and Treatment Evaluation (RAATE). Internal consistency reliabilities (alpha) ranged from 63 to 78. The Texas Christian University Client Evaluation of Self and Treatment is the third instrument under investigation, internal consistency reliabilities (alpha) range from 0.58 to 0.96. What measures would you recommend? Why? What measures would you have concerns about? Why?

1) The following data were collected from a repeated-measures study investigating the effects of 4 treatment conditions on test performance. Determine if there are any significant differences among the four treatments. State the null hypothesis. If you determine a significant treatment effect, use Tukey’s HSD test (overall α = .05) to determine which treatments differ from which other treatments. Also, compute the percentage of variance explained by the treatment effect (η2). Conclude with an appropriate summary describing what you found....
