pdf Finding The Mean

This worksheet provides structured practice calculating the mean of various numerical data sets. Students are given multiple sets of whole numbers and decimals and must compute the sum, identify the number of data points, and divide to determine the mean. A completed example models the full process, including organizing work within a table format that separates the data set, total sum, divisor, and final mean.

Because the problems vary in size and complexity, students practice calculating averages with both small and large values, as well as decimal numbers. The inclusion of an organized table reinforces procedural clarity and helps students connect the formula for mean to its practical application: adding all data values and dividing by the total number of values.

This resource works well as guided practice when introducing mean, independent reinforcement, homework, or formative assessment within a statistics and data analysis unit.
