Statistics - Solve for Mean from Sum and Count (Level 1)

This math topic focuses on calculating the mean of a set of numbers. Specifically, it involves finding the average by dividing the sum of given numbers by their count. This topic includes multiple-choice questions where learners practice computing the mean for various sums and counts of numbers, enhancing their understanding of basic statistics within the context of probability and statistics—mean, median, and mode. Each question presents a different sum and count scenario, requiring the application of the mean formula: mean = sum of numbers / count of numbers.
