WebThe test statistic for a goodness-of-fit test is: ∑ k (O−E)2 E ∑ k ( O − E) 2 E. where: O = observed values (data) E = expected values (from theory) k = the number of different data cells or categories. The observed values are the data values and the expected values are the values you would expect to get if the null hypothesis were true.
