How do you find the expected value in a chi-square test?

To calculate the expected numbers a constant multiplier for each sample is obtained by dividing the total of the sample by the grand total for both samples. In table 8.1 for sample A this is 155/289 = 0.5363. This fraction is then successively multiplied by 22, 46, 73, 91, and 57.

What is the expected value of a chi-square distribution?

The expected value of a chi-squared random variable is equal to its number of degrees of freedom.

How to calculate expected frequency in chi-square calculator?

To calculate the expected frequency, add together the total of the ith row and the total in the jth column, then divide the result by the total.
