Chi Square Test in SPSS Interpretation with Example Summary

Chi Square Analysis chi square test in spss interpretation interpretation of chi square test results in spss with Example Summary 

If sig value > 0.05 then accept H₀

If sig value <= 0.05 then accept H₁

Assumptions

·         Sample must be random and independently distributed

·         Each unit in the cell has the same probability being from a particular cell

·         Each observation may be categorized either into class 1 or class 2 etc

Solution

1.       H₀ : Sample is independent

2.       H₁ : There is association

3.       Sig value: 0.05

For simple category Analysis

Check expected count if any value is less than 5 then use “Likehood/contingency table” than pearson chi square method

·         If 2*2 then use risk and see phi

·         If 2*3, 2*4 then use contingency table

·         If 3*3, 4*4, 5*5 then use cramer-v

Kappa Applied

When use:

·         when rows and columns have same name.

·         use for qualitative variable want to see index of agreement b/t observation

Solution:

·         Click on statistics “kappa”

·         In kappa column value tell (index of agreement)

·         If want to see sig value then see “Asymp std error” value.

Nominal Data

When use:

Category is not properly defined e.g

·         Over, proper, under

·         High dose, recommended dose, low dose

If data is not in order then see “Linear by Linear” in chi square table.

Kandall-tau b test

When use

To check one value is decreasing & another value is increasing. For qualitative

Solution:

·         Click on “co-relation”

·         Click on “kandrall-tau-b”

·         Check kandrall value in table if value is (-ve) mean one value is decreasing & another value is increasing

Cochran-Mantel-Haenszel

When use:

·         When there is group like “city” etc

·         Want to group/pool element

·         When there is more than rows and column in table

Solution

·         Enter city column in pool
