Random Rectangles When given the cue turn the paper over. Within 5 seconds make a guess for the average area of the rectangles. When given the cue turn the paper over. Select 5 rectangles you think are representative of the rectangles on the page. Write the rectangle numbers and their areas. Compute the average of the 5 rectangles. Math Alliance Project

Random Rectangles Use the random-number generator on the graphing calculator to select five different numbers from 1 to 100. Write down the five numbers and the area of each of the five rectangles. Find the area of the five rectangles. Math Alliance Project

Random Rectangles Report the three answers that you found for the average of the rectangles. Guess Representative sample Random sample At your table construct 3 box plots Math Alliance Project

Random Rectangles Compare the three box plots. Describe any similarities and differences. Compare the medians of the three box plots to the actual area of all 100 rectangles. Math Alliance Project
