This math topic focuses on practicing the calculation of the mean (average) in a set of numbers from which a single value has been removed. It challenges students to identify which specific number, when taken out from a set, will result in a given mean. The problems are structured in a multiple-choice format with sets of three numbers and a target mean for students to achieve by removing one of the numbers. This skill is essential for understanding statistical concepts and developing analytical skills in handling numerical data.
