Statistics aplet Key CLEAR Meaning (Continued) Displays the menu for entering variable names or contents of variables. Displays the menu for entering math operations. Deletes the highlighted variable or the current character in the edit line. Resets default specifications for the data sets or clears the edit line (if it was active). Note: If CLEAR is used the data sets will need to be selected again before re-use. To continue our example, suppose that the heights of the rest of the students in the class are measured, but each one is rounded to the nearest of the five values first recorded. Instead of entering all the new data in C1, we shall simply add another column, C2, that holds the frequencies of our five data points in C1. Height (cm) 160 165 170 175 180 Frequency 5 3 8 2 1 5. Move the highlight bar into the right column of the H1 definition and replace the frequency value of 1 with the name C2. 2 10-9
