How it Works
To illustrate, suppose we have a sample of exam scores with the following values: 80, 90, 70, 85, and 95. To calculate the sample mean, we add up the scores (80 + 90 + 70 + 85 + 95 = 420) and divide by the sample size (5). This gives us a sample mean of 84.
Conclusion
Why it's Trending Now
The sampling mean formula is a fundamental concept in statistics that allows researchers to estimate population parameters from a sample of data.
