Breathtaking Scatter Plots

In this activity, students will gather data by recording estimates of how long they think they can hold their breath and the actual amount of time. Then, they will create scatter plots and box plots to analyze the data.

Box Plots and Histograms

Students create and explore a box plot and histogram for a data set. They then compare the two data displays by viewing them together and use the comparison to draw conclusions about the data.

We Have the Same Birthday

In this activity, students use simulations to answer a popular question involving probabilities. They will use the randInt and mean commands to determine the average number of people that need to be in a room to share a birthday.
