ID	80.7	SD	78.3
KS	86	UT	85.2
MA	80.8	WA	85.1
M1	64.8	WY	82.9

Graph:

In this case, histogram is an appropriate choice of graph because the data set is large and continuous.

Follow the provided steps of Ti-83 to construct the figure as:

1. Click on 2nd > STAT PLOT > Plot 1 > ENTER.
2. Click On and select histogram as type.
3. Click on STAT > Edit > Enter
4. Enter data values in L1.
5. Click on Zoom >ZoomStat> ENTER
6. Click on TRACE to toggle the all the bars of the histogram.

The obtained output is:
