Q:

How is relative frequency calculated?

A:

To calculate relative frequency, get the total of the provided data, and divide each frequency by the answer. The total figure is found by adding every number in the provided classes.

  1. Identify the classes and frequencies

    The class of the data is mostly represented by letters. The frequency is the set of numbers under each class. For instance, a particular class of data would show that 10 students got grade A, 12 students got grade B, 21 students got grade C, 15 students got grade D, and 12 students had grade E.

  2. Calculate the relative frequency

    Add the number of students to find the total attendance during the test. Therefore, by adding 10+12+21+15+12, you get 70, which is the total attendance.

  3. Divide each frequency by the total figure

    Pick each number in the class, and divide it by the total attendance. Hence, 10/70= 0.14, 12/70= 0.17, 21/70= 0.3, 15/70= 0.21 and 12/70= 0.17. The numbers in decimal points are your relative frequencies. Convert them into percentage form by multiplying them by 100.

  4. Match the results with their grades

    From your answer, you realize that 14 percent of students got grade A, 17 percent got grade B, 30 percent got grade C, 21 percent got grade D, and 17 percent got grade E. If the question does not need the answer in percentage form, then leave it as a decimal or whole number. Use this example to calculate the relative frequency of other statistical data.

  • Q:

    What is frequency measured in?

    A:

    The most common unit used to measure frequency is hertz (Hz), which refers to cycles per second; however, there are some other ways to measure frequency, such as revolutions per minute (RPM) for a motor or beats per minute (BPM) for a person's heartbeat. Frequency refers to how often an event occurs in a specific time frame, such as a minute or second.
