Math Problem Statement
Solution
Here are the calculations based on the given dataHere are the calculations based on the given
- Sample Mean = 31.98
- Sample Standard Deviation = 6.53
- Sample Variance = 42.67
- Population Standard Deviation = 6.11
Would you like a more detailed explanation or further assistance with these results?
Here are 5 related questions to expand your understanding:
- How does the calculation differ between a sample and a population?
- What is the significance of the degrees of freedom in standard deviation calculations?
- How does the variance relate to the standard deviation?
- Why is it important to know whether you're working with a sample or a population?
- Can you explain how outliers affect the mean and standard deviation?
Tip: For a dataset with only a few values, outliers can significantly affect both the mean and standard deviation, so it's important to analyze them separately.

Formulas
Sample Mean = (Σx) / n
Sample Standard Deviation = sqrt[(Σ(x - mean)^2) / (n - 1)]
Sample Variance = (Σ(x - mean)^2) / (n - 1)
Population Standard Deviation = sqrt[(Σ(x - mean)^2) / n]
