As students report measurements on circumference and diameter of objects, the spreadsheet calculates their ratio and averages them together to approximate pi.
The student enters data and then the spreadsheet generates several measures of that data such as mean, median, mode, quartiles, and range, which the user can investigate and compare.
Three different sets of data (earnings, votes, heights) are shown with three different types of graphs (line, bar, circle). The student is to compare the different graphs to determine which is the best representation.
As the user enters values for the numerator and denominator of a fraction, a circle graph is generated to show a visual representation of the fraction.
