Understanding the Sample Mean

The sample mean is the average value of a sample set of numbers. It's calculated by summing all the values in the sample and dividing by the number of values in the sample.

When to Use the Sample Mean

The sample mean is a fundamental statistical measure used in:

  • Describing central tendency in a dataset
  • Comparing different groups of data
  • Conducting hypothesis tests in inferential statistics
  • Estimating population parameters from sample data

Example

If you enter the sample data 5,7,9,12,15, the calculator will compute:

  • Sum: 48
  • Count: 5
  • Sample Mean: 9.6
