Lessons tagged with "average"

This statistics, data analysis, and probability lesson focuses on computing the mean, median, and mode of data sets. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students order the numbers from least to greatest. Then, they compute the mean by adding all the values in the data set and dividing by the number of items. They compute the median by identifying the middle number, realizing that if there is an even number, they will need to find the sum of the two middle values and divide by two. They compute the mode by identifying the most frequent number in the data set. In addition to the lesson, there are eight pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items.
