The mean is not the value among the observations that occurs most often. The mean, also known as the average, is a statistical measure that calculates the central tendency of a set of numbers. It is obtained by adding up all the values in a dataset and then dividing the sum by the total number of values.

To calculate the mean, you follow these steps:

  1. Add up all the values in the dataset.
  2. Count the total number of values in the dataset.
  3. Divide the sum by the total number of values.

For example, let’s say we have the following dataset: 2, 4, 6, 8, 8, 10, 10. To find the mean, we add up all the values: 2 + 4 + 6 + 8 + 8 + 10 + 10 = 48. Since there are 7 values in the dataset, we divide the sum by 7: 48 / 7 = 6.857. So the mean of this dataset is 6.857.

The mean is a useful measure of central tendency because it provides a representative value of the dataset. It can be affected by extreme values, called outliers, so it’s important to consider the entire dataset when interpreting the mean.
