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.

WebChi-square goodness of fit test proof. I understand the classcial χ 2 "goodness of fit" test used in Statistics, in which we compute ∑ i = 1 n ( O i − E i) 2 E i and, by comparing this quantity to a value found in a table of χ 2 law (with a given risk α = 5 % for example), we decide if we should or not accept the hypothesis that the ... WebMar 26, 2024 · The test is known as a goodness-of-fit χ 2 test since it tests the null hypothesis that the sample fits the assumed probability distribution well. It is always right-tailed, since deviation from the assumed probability distribution corresponds to large values of χ 2. Testing is done using either of the usual five-step procedures.
