This math topic focuses on calculating the mean (average) of a set of numbers given their sum and count. By dividing the sum of values by the number of values in each problem, students practice determining the mean. The topic includes multiple-choice questions where learners must select the correct mean for sets of 3, 4, or 5 numbers with different total sums. This topic is essential for understanding basic statistical concepts and is part of a larger unit on mean, median, and mode within probability and statistics.
