Chi squared test statcrunch
Web- A t-distribution is the ratio of a Standard Normal divided by the square root of a Chi-square divided by it's degrees of freedom, e.g., Z / sqrt ( C/c ), where Z is a standard normal RV, C is the Chi-square RV, and c is the degrees of freedom. WebMinitab calculates each cell's contribution to the chi-square statistic as the square of the difference between the observed and expected values for a cell, divided by the expected value for that cell. The chi-square statistic is the sum of …
