The bar graphs for relative frequency and percentage distributions can be drawn simply by marking the relative frequencies or percentages, instead of the class frequencies. Pie Chart A circle divided into portions that represent the relative frequencies or percentages of a population or a sample belonging to different categories.

The number associated with each category is called the frequency and the collection of frequencies over all categories gives the frequency distribution of that variable. The relative frequency is a number which describes the proportion of observations falling in a given category. Instead of counts, we report relative frequencies or percentages.

The expected counts are all large, so we preceed with the chi-square test. We compare the table of observed counts with the table of expected counts using the statistic. We must calculate the term for each, then sum over all nine cells. For the high-SES current smokers, the observed count is 51 and the expected count is 68.75.

Counts (frequencies) instead of percents (relative frequencies)—not appropriate when comparing groups of unequal size. Nonstandard graphs of many varieties. No label or incorrect label on vertical axis. Condition based on one variable, but draw the graph as if they conditioned on the other. Part (b) Describing shape, center, or spread
