Senior Mathematics Faculty Interview Questions and Answers

Cumulative frequency is the running total of the frequencies in a frequency distribution.

• Cumulative frequency is calculated by adding up the frequencies as you move through the data.

• It helps in determining the number of observations that lie below a certain value in a data set.

• Cumulative frequency can be used to create cumulative frequency distribution or cumulative frequency polygon.

• For example, if the frequency of a certain value is 5 and the cumulative frequency up to that...read more
