Study 1. Directed Reading Activities

Open reading.sav

This data set provides reading performance of two groups of pupils - one control group that was NOT given Directed Reading Activities and one group that was given Directed Reading Activities (Moore et al., 2012, p.432). We will compare two groups of students with the aim of testing whether the Directed Reading Activities can enhance the performance of pupils on Degree of Reading Power Test.

id - participant ID number

g -Group indicator expressed as a binary variable (0=Directed Reading Activities, 1=control group)

drp - the performance on Degree of Reading Power Test.

Based on the research goal, answer question below:

1.Proper test statistic:

2.Identify the:

Indep.variable_________________________Dep.variable______________________

3.State hypotheses in words:

H₀:_____________________________________________________________________

H₁:_____________________________________________________________________

4.Perform the proper t-test using SPSS. Also create a boxplot (use chart builder) showing Degree of Reading Power Test for the experimental and the control group. Paste all the output tables and the boxplot below.

5.Can we assume the variances are equal based on this Levene test? Why or why not?
