Frequently Asked Questions (FAQ)
What is variance? Variance is a measure of how far each number in a data set is from the mean.
How is standard deviation different from variance? Standard deviation is simply the square root of variance, offering a measure in the same unit as the data set.
Why is sample size important? A larger sample size leads to more accurate and reliable statistical results.
How do I calculate the mean? The mean is calculated by adding all values in the data set and dividing by the number of values.
