Is goodness-of-fit test the same as chi-square?
In Chi-Square goodness of fit test, the term goodness of fit is used to compare the observed sample distribution with the expected probability distribution. Chi-Square goodness of fit test determines how well theoretical distribution (such as normal, binomial, or Poisson) fits the empirical distribution.
Why is this not an appropriate use of a chi-square goodness-of-fit test?
The Chi-square goodness of fit test is not appropriate for continuous data. A data set that is large enough so that at least five values are expected in each of the observed data categories.

Is the chi squared test based on K?
If this is the case, then a chi squared test based on two squared differences of samples (perhaps corresponding to customers coming in only on Friday and Saturday) would be based on the k = 1 curve, which seems wrong to me. Can you explain? Reply to Christopher Black’s post “In the previous video int…”
Who is the creator of the chi square test?
