Relative Frequency

Relative frequency is a statistical measure that describes the number of times a particular event occurs in a data set, relative to the total number of events. It is often expressed as a fraction, decimal, or percentage.

Calculating Relative Frequency

To calculate the relative frequency of an event, you can use the following formula:

Relative Frequency = (Number of times the event occurs) / (Total number of events)

Example

Suppose you have a data set of 100 students and you want to calculate the relative frequency of students who prefer math. If 25 students prefer math, you would calculate the relative frequency as follows:

Relative Frequency of Math Preference = 25 / 100 = 0.25 = 25%

Study Guide

Understand the concept of relative frequency and how it is used in statistics.
Learn how to calculate relative frequency using the formula: Relative Frequency = (Number of times the event occurs) / (Total number of events).
Practice calculating relative frequency with different data sets and events.
Understand the relationship between relative frequency and probability, and how relative frequency can be used to estimate probabilities.

By mastering the concept of relative frequency, you will be able to analyze and interpret data more effectively, and make informed decisions based on statistical information.

Grade 6 Curriculum Focal Points (NCTM)

Number and Operations: Connecting ratio and rate to multiplication and division

Students use simple reasoning about multiplication and division to solve ratio and rate problems (e.g., 'If 5 items cost $3.75 and all items are the same price, then I can find the cost of 12 items by first dividing $3.75 by 5 to find out how much one item costs and then multiplying the cost of a single item by 12'). By viewing equivalent ratios and rates as deriving from, and extending, pairs of rows (or columns) in the multiplication table, and by analyzing simple drawings that indicate the relative sizes of quantities, students extend whole number multiplication and division to ratios and rates. Thus, they expand the repertoire of problems that they can solve by using multiplication and division, and they build on their understanding of fractions to understand ratios. Students solve a wide variety of problems involving ratios and rates.
