This math topic involves calculating the single number that can be added to a set of given numbers to achieve a specified change in their mean. Problems involve either an increase or decrease in the mean. Each problem provides a set of numbers and a target change in the mean, and students must select the correct number from multiple choices that will result in the described change in mean. This practice is part of a broader unit focused on advanced concepts of mean, median, and mode within the field of probability and statistics.
