2 by 2 Contingency Table Analysis (Pearson Chi-Square) - SPSS (part 1)

I demonstrate how to perform and interpret a 2 by 2 contingency table analysis ins SPSS. I also demonstrate Cramer's V and Phi and how they are identical to the Pearson correlation.

Thank you for helpful videoes I have a question I have measured specificity and sensitivity of a dich. Test and used layer to divide the measurements by age groups is there any way to compare the spe and sen for groups? There are 4 groups and for each i have spe and sen and as i mentioned they are separated (layer by age group in crosstab window) Id be grateful if you answer my question🙏

for my master's thesis i need to compare the prevalence of type D personality in 2 different diseases. My professor told me to use a chi² test, I made 2 colums for every disease and then filled out the rows with either 0 or 1 0 meaning no type D personality and 1 meaning type D personality but the results are really weird. Does anyone know how to go about it ?

What's the difference between using the contingency table and using the pearson correlation in the analyze>correlation menu?

[howstats]

Yes, r x c contingency table analyses are legitimate; typically, though, you're left having to do a series of 2 x 2 contingency table analyses to help understand the omnibus effect. Another way is to look at the adjusted standardized residuals. You also must look at Cramer's V rather than Phi in the r x c case.

[howstats]

In the 2 x 2 between groups case, there is no difference between the Pearson chi-square and the Pearson correlation coefficient.

Basically, you can test the same hypothesis by using Binary Logistic Regression. Moreover, in the output you would get to see odds denoted as Exp(B), which tells you how much left-handed people are more likely to have dyslexia than right-handed people.

Is Yates' correction also applied in SPSS to 2 by 2 contingency table analysis using Pearson's chi-square test?
If yes, is there a macro I can use to get the uncorrected chi-square (like Garcia-Granero's macro for McNemar test)?
