This math topic involves practicing how to adjust the collection of values in a data set to achieve a specified mean, specifically by identifying which single value needs to be removed. This skill is essential for understanding the impacts of data manipulation on statistical measures and is part of an advanced unit focusing on mean, median, and mode within probability and statistics. Each question provides a set of numbers and a target mean, and the learner must determine which specific number, once removed, results in the target mean. This involves both critical thinking and basic arithmetic operations.
