This calculator uses this formula to perform the calculation.
Real-World Examples
Example 1
Let’s say you have two datasets, A and B. Dataset A has a mean of 10 (u) and Dataset B has a mean of 15 (w). Using this calculator, you can find the difference between the means of the two datasets:
w-u = 15 – 10 = 5
Example 2
In a study, the average height of men (u) is 5.9 feet, and the average height of women (w) is 5.4 feet. The difference in average heights is:
w-u = 5.4 – 5.9 = -0.5
Example 3
In a survey, the average salary of engineers (u) is $75,000, and the average salary of doctors (w) is $200,000. The difference in average salaries is:
w-u = 200,000 – 75,000 = $125,000
Data & Statistics
| Dataset | Mean (u) | Standard Deviation |
|---|---|---|
| Dataset 1 | 15 | 3.5 |
| Dataset 2 | 20 | 4.2 |
| Country | Average Life Expectancy (w) | Average Life Expectancy (u) | Difference (w-u) |
|---|---|---|---|
| Japan | 84.6 | 78.5 | 6.1 |
| Switzerland | 83.8 | 81.2 | 2.6 |
