Study 1. Directed Reading Activities: Computer Assignment2 Comparing means

Open reading.xlsx.

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.

Computer Assignment2 Comparing means

id – participant ID number

g – Experimental 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:_______________________________________
