This math topic focuses on understanding how the mean of a set of numbers changes when a single value is removed. It presents multiple problems where students need to figure out which number can be removed from a given set to achieve a specified change in the mean. This involves critical thinking and application of statistical concepts within the broader unit of Probability and Statistics, particularly focusing on Mean, Median, and Mode at an advanced level.
