pdf Find Missing Value When Given The Mean

This worksheet provides structured practice solving real-world problems involving a missing value when the mean is given. Students must work backward from an average to determine an unknown data point, strengthening their understanding of mean as total divided by number of data values.

Each problem presents a different context, including rainfall totals, test averages, player heights, fish weights, soccer goals, and canned food collection totals. Students calculate the total sum implied by the given mean, subtract the known values, and determine the missing amount. Because the problems require multi-step reasoning and careful organization, the worksheet reinforces both conceptual understanding and procedural accuracy.

By connecting averages to authentic scenarios, this resource helps students move beyond simple computation and recognize how mean represents a balance point within a data set. It works well as guided practice, independent work, homework, or assessment within a statistics and data analysis unit.
