NOTE: This dataset is fairly small (n=32). It may be just as fast to enter the data yourself directly in L1.
The data for actor's age is stored in L1.
Now create a histogram of the actors' age data:

Y=/CLEAR
, or else toggle them off by choosing Y=
and then pressing the left arrow until =

ON
, then press ENTER
.Type:
Histogram is third graph.Xlist: L1 (2ND/1)
.Freq: 1
(the number one).First we need to determine the class width and what lower value we want for our first class. In this case, our minimum data point is 31, and our max is 76. We'll use a class width of 5, and make classes from 30 to 80.
WINDOW
, and set the following values: GRAPH
.TRACE
and then use the left and right arrows to move the cursor around the histogram to see the values for each bar.
