Practical Example

Let’s say a student enters the dataset:

5, 7, 7, 10, 12, 15, 18

If choosing Basic Stats:

  • Mean: 10.57
  • Median: 10
  • Mode: 7
  • Range: 13
  • Standard Deviation: 4.65
  • Variance: 21.65
  • Q1: 7
  • Q3: 15
  • IQR: 8

If choosing Z-Score for the value 12:

  • Mean = 10.57
  • Std. Dev = 4.65
  • Z = (12 – 10.57) ÷ 4.65 = 0.31

If choosing Percentile Rank for the value 12:

  • 5 out of 7 numbers are below 12 → Percentile Rank = 71.43%

This example shows how versatile the calculator is for different statistical needs.
