Question

The school psychologist used a measure to classify children as showing some form of learning disorder. She also examined school records and noted which were enrolled in a remedial Math. Below is the contingency table of the data. What can be concluded with ? = 0.05?

	Remedial
Disorder	no	yes
none	23	78
aphasia	56	75
dysgraphia	20	22

a) What is the appropriate test statistic?
---Select--- na z-test One-Sample t-test Independent-Samples t-test Related-Samples t-test One-Way ANOVA Within-Subjects ANOVA Two-Way ANOVA Correlation Slope Chi-Square GoF Chi-Square Independence
Compute the statistic selected in a):

b) Obtain/compute the appropriate values to make a decision about H₀.
Critical Value =  ; Test Statistic =
Decision:  ---Select--- Reject H0 Fail to reject H0

c) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
Effect Size =  ; Magnitude:  ---Select--- na trivial effect small effect medium effect large effect

d) Make an interpretation based on the results.

There is a significant positive relationship between learning disorder and remedial Math.There is a significant relationship between learning disorder and remedial Math. Learning disorder Math and remedial are independent.
