Median and Interquartile Range
In this lesson students are introduced to the median and, by taking the median of each half of the data, to quartiles and the interquartile rangehttps://education.ti.com/en/activity/detail/medians-and-iqrs-bc
Mean As a Fair Share
This lesson introduces students to mean as a way to describe the center of a set of data. Often called the average, the mean can also be visualized as “leveling out” the data in the sense of “fair share”.https://education.ti.com/en/activity/detail/mean-as-a-fair-share-bc
Mean As A Balance Point
In this lesson, students calculate deviations from the mean, how far each value is above or below the mean. Students also focus on the balance point of a distribution, where the sum of the absolute deviations below the mean is equal to the sum of the absolute deviations above the mean.https://education.ti.com/en/activity/detail/mean-as-a-balance-point-bc
