Answer:
The test statistic value is, <em>t</em> = -5.245.
The effect size using estimated Cohen's d is 2.35.
Step-by-step explanation:
A paired <em>t</em>-test would be used to determine whether the remedial tutoring has been effective for the statistics tutor's five students.
The hypothesis can be defined as follows:
<em>H</em>₀: The remedial tutoring has not been effective, i.e. <em>d</em> = 0.
<em>Hₐ</em>: The remedial tutoring has been effective, i.e. <em>d</em> > 0.
Use Excel to perform the Paired <em>t</em> test.
Go to Data → Data Analysis → t-test: Paired Two Sample Means
A dialog box will open.
Select the values of the variables accordingly.
The Excel output is attached below.
The test statistic value is, <em>t</em> = -5.245.
Compute the effect size using estimated Cohen's d as follows:
Thus, the effect size using estimated Cohen's d is 2.35.
