Question

which of the following best describes a cumulative frequency table? a table showing only the highest frequency a table showing the frequency of each individual class interval a table showing the mean of each class interval a table showing the running total of frequencies up to each class interval

The other options describe a modal frequency table, a regular frequency table, and a class mean table respectively, which do not match the definition of cumulative frequency.

Answer:

D. A table showing the running total of frequencies up to each class interval
