Smallest expected count calculator
WebbAs such, you expected 25 of the 100 students would achieve a grade 5. However, in reality, 30 students achieved a score of 5. As such, the chi-square calculation is as follows: X 2 = (30 - 25) 2 / 25 = (5) 2 / 25 = 25 / 25 = 1. An In-depth Example of the Chi-square Calculator. Let's take a more in-depth look at the paper grading example. WebbTo 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. For sample B the fraction is 134/289 = 0.4636.

You can use this chi-square calculator as part of a statistical analysis test to determine if there is a significant difference between observed and expected WebbTo do this, you subtract 0.5 from each observed value that is greater than the expected, add 0.5 to each observed value that is less than the expected, then do the chi-square or G –test. This only applies to tests with one degree of freedom: goodness-of-fit tests with only two categories, and 2×2 tests of independence.
