Beginner Explanation
A statistical question is one that expects different answers because it deals with variability in data. For example, 'What is the average number of hours students study per week?' requires collecting data and computing measures like the mean. To compute the mean (average), use $\bar{x} = \frac{\Sigma x_i}{n}$.
