What is Sample Mean?

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

Formula

Sample Mean (x̄) = Σx / n

Where:

  • Σx = Sum of all sample values
  • n = Number of sample values

Applications

The sample mean is widely used in statistics to:

  • Estimate the population mean
  • Perform hypothesis testing
  • Analyze experimental data
  • Compare different sample sets

Example

For a sample set {5, 8, 12, 15, 20}:

  1. Sum = 5 + 8 + 12 + 15 + 20 = 60
  2. n = 5
  3. Sample Mean = 60 / 5 = 12
