What should be the P value for Chy Square test please

Dear Saunak,

Are you asking how to calculate the P values for Chi-Square test?

SJ.

Sir,

I am actually trying to find out what should be the ideal P value

If you are comparing four proportions and are interested in doing a Chi-Square test, your null and alternate hypothesis would be:

Ho: P1 = P2 = P3 = P4

Ha: At least one proportion is different.

Based on your chi-square test, you will get a Chi-Sq and P value.

If your P > alpha, then you conclude Ho is true.

If your P < alpha, then you conclude Ha is true.

Alpha is your significance level and (1-Alpha) is your confidence level. Depending on how much confidence you need in your analysis you would select the appropriate value of alpha. Default value for alpha is 0.05 (Confidence level = 95%).

There is no such thing as an ideal value of P, though you could argue that if P = 0 or 1, then we can clearly select Ha or Ho without any doubt!
