Microsoft Excel and the other spreadsheet programs (Apple Numbers, Google Sheets, or LibreOffice Calc) can calculate the goodness of fit directly; they return a P-value only. WebIn “Chi-Square Test for One-Way Tables,” we learned an inference procedure called the chi-square goodness-of-fit test. A goodness-of-fit test determines if the distribution of a categorical variable in a sample fits a claimed distribution in the population, or not. We can answer the following research questions with a chi-square goodness-of ...
