Question

Quizplus · Accepted Answer

A relative frequency table summarizes data by expressing the fraction or proportion of the total number of items in each class, rather than the actual number of items (as in a frequency table). This type of table is useful for comparing different data sets or for showing the distribution of data as percentages. Normal frequency tables and cumulative frequency tables are types of frequency tables that show the actual number of items in each class, but do not express them as fractions or proportions of the total.
