The chi-square test is used to analyze a contingency table consisting of rows and columns to determine if the observed cell frequencies differ significantly from the expected frequencies.

How to get expected frequency value in chi square test?
For goodness of fit test using Chisquare test, Expected frequency = Total number of observations * theoretical probability specified or Expected frequency = Total number of observations / Number of categories if theoretical frequencies are not given. For contingency tables (test for independence) Expected frequency = (Row total * Column total) / Grand total for each cell
What is the definition of chisquare?
Chi-square is a statistic used to assess the degree of the relationship and degree of association between two nominal variables
What are the limitations of the WAISR IQ test?
uses of wais -r
What are t test and F test In which situation these are applied?
Both are parametric test. The t-test uses a test statistic that is related to the sample mean(s) and is used to compare that with the mean of another sample or some population. The F-test uses a test statistic that is related to the sample variance and is used to compare that with the variance of another sample or some population. Both tests require identical independently distributed random variables. This ensures that the relevant test statistics are approximately normally distributed.
When do you use an F test?
When testing the sums of squares of variables which are independently identically distributed as normal variables. One of the main uses of the F-test is for testing for the significance of the Analysis of Variance (ANOVA) or of covariance.

What are the two major differences between park test and white test?
park test is when you know the zed that you want to use, and white test is when you can't decide which park test to use. The park test uses t values, whereas the white test uses chi squares values
