Descriptive statistics
Mean, median, mode, spread and standard deviation for your numbers.
A clear answer. Here’s how.
Mean is the sum divided by count; the median is the middle sorted value. Population standard deviation divides squared deviations by n; sample standard deviation uses n−1. Modes show repeated values only. No missing-value imputation is performed.
