Drawing the Probability Histogram of a Discrete PDF

- Enter the values of
*X*into list L_{1}. - Enter the probabilities
of
*X*into list L_{2}. - Press 2
^{nd}STAT PLOT. The STAT PLOTS menu appears. - Use the arrow keys to
select item #1, Plot1.
- Press ENTER. The Plot1 menu appears.
- Select On. (It is already highlighted.)
- Press ENTER.
- Press the down arrow
once.
- Select the histogram
type of plot. (It is the third
one.)
- Press ENTER.
- Press the down arrow
once.
- Press 2
^{nd}L_{1}. - Press the down arrow
once.
- Press 2
^{nd}L_{2}. - Press WINDOW. The WINDOW menu appears.
- To the right of Xmin, enter a value at
least as small as the smallest value of
*X*in list L_{1}. - Press the down arrow
once.
- To the right of Xmax, enter a value at
least as large as the largest value of
*X*in list L_{1}. - Press the down arrow
once.
- To the right of Xscl, enter the smallest
difference between any two values of
*X*. Typically, this will be 1. - Press the down arrow
once.
- To the right of Ymin, enter 0 (minimum
probability).
- Press the down arrow
once.
- To the right of Ymax, enter a value at
least as large as the largest probability in list L
_{2}. - Press GRAPH. The probability histogram of the pdf of
*X*appears in the display.
