Calculating a Relative Frequency

Relative Frequency Lesson Description

Students learn how to calculate an expected frequency from a probability experiment, using relative frequency to estimate outcomes in real-world contexts.

Later, as learning progresses, they consider the probabilities of mutually exclusive events, comparing experimental and theoretical probability.

Differentiated Learning Objectives
  • All students should be able to use an experimental or theoretical probability to calculate an expected frequency.
  • Most students should be able to use the sum of mutually exclusive events to calculate an expected frequency.
  • Some students should be able to use an expected frequency to calculate the sample size.
