What information can come from a box? Learners choose a data set to display as a box plot and decide whether to include the median in the calculation of the quartiles, show the outliers, and change the scale. To finish the lesson,...

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...

Class members investigate relationships between two variables in the seventh installment of a 16-part module that teaches scholars how to find and describe patterns in scatter plots. Young mathematicians consider linear/nonlinear...

Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

Students practice using graphing tools to make tables, bar charts, scatter graphs, and histograms, using census data. They apply the concept of measures of central tendency, examine the effects of outliers. They also write inferences and...

In this data management and probability applications worksheet, 8th graders solve 20 various types of probability problems. They find the mean, median, mode and range of various numbers. Then, students use the spinner illustration to...

In this line plot worksheet, students create a line plot of given data. They identify the range, clusters, gaps, and outliers. This one-page worksheet contains 8 multi-step problems.

Pupils explore proportions which are typical of the human body. Given a list of classic proportions from earlier centuries, students work in pairs to test the validity of the proportions. Pupils share their personal measurements. They...
