Explore the effect of outliers through an analysis of mean, median, and standard deviation. Your classes examine and compare these measures for two groups. They must make sense of a group that has a higher mean but lower median compared...

Discover relationships between linear and nonlinear functions. Initially, a set of data seems linear, but upon further exploration, pupils realize the data can model an infinite number of functions. Scholars use multiple representations...

The key is in the leaves. Pupils enter data to create a stem-and-leaf plot. The resource then displays the plot and calculates the mean, median, and mode of the data. Using the plot and the calculated measures of spread, learners analyze...

Slide the class into a skewed view. Learners alter the location of the median relative to the mean of a normal curve to create a skew distribution. They compare the curve to a histogram distribution with the same skewness. 

Students investigate temperature using the TI. In this chemistry lesson, students analyze the change in temperature, as chemicals are dissolved in water. They analyze data collected using the CBL 2.
