Histogram
Now we will use our graphic calculators to draw a distribution curve based on the measured
diameters of the 100 rods.
We will use the program mode and use random numbers as the measured data. See "Program
Creation" on the next page for information about the program.
Note
Calculator key operations and displays are indicated
inside the broken line box.
