Which represents the number of times all outcomes less than a given outcome occur? cumulative frequency relative frequency frequ
max2010maxim [7]

Answer: cumulative frequency

Step-by-step explanation:

  • A frequency is the number of times a data value occurs.
  • A relative frequency is the fraction or proportion of times an answer occurs.
  • The cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value.

In a data set, the cumulative frequency for a value x is the total number of scores that are less than or equal to x.

Hence, cumulative frequency represents the number of times all outcomes less than a given outcome occur.
