Question

Explain how to use a calculator to find the mean of a frequency distribution.

Answer 1

To find the mean of a frequency distribution using a calculator, create a chart, multiply each value by its frequency, and divide the sum by the total number of data values.

Step-by-step explanation:

To find the mean of a frequency distribution using a calculator, follow these steps:

1. Create a chart containing the data and their corresponding frequencies.
2. Multiply each value by its frequency to get the total sum.
3. Divide the sum by the total number of data values to calculate the mean.

For example, if the frequency distribution is [1, 2, 3] with frequencies [4, 6, 2], the calculation would be ((1 * 4) + (2 * 6) + (3 * 2)) / (4 + 6 + 2) = 2.2. Therefore, the mean of the given frequency distribution is 2.2.
