WebMay 23, 2024 · A chi-square test (a chi-square goodness of fit test) can test whether these observed frequencies are significantly different from what was expected, such as equal frequencies. Example: Handedness and nationality. Contingency table of the handedness of a sample of Americans and Canadians. Right-handed. Left-handed. WebA mosaic plot is a special type of stacked bar chart. For two variables, the width of the columns is proportional to the number of observations in each level of the variable plotted on the horizontal axis. The vertical length of the bars is proportional to the number of observations in the second variable within each level of the first variable.
