*The following shows the parameters that the unit uses for the probability distribution graph. Ymin Ymax -0.1- OAS Xmin Xmax - 3.2 - 3.2 8-8 Single-Variable Statistical Graphs To draw single-variable statistical graphs, you must use the SD Mode and the statistica graph DRAW Mode. The unit lets you draw bar graphs, line graphs and normal distribu tion curves using data you input. Fs (SET) (or Iffirrimsal (9[E(DRVV) • To draw a bar graph Example To draw a bar graph of the following data: Rank Value Frequency 1 0 1 2 10 3 3 20 2 4 30 2 5 40 3 6 50 5 7 60 6 8 70 8 9 80 . 15 10 90 9 11 100 2 First, specify the range parameters. Since the maximum data value for xis 100, we will set Xmax as 110, The maximum data value for y is 15, so set Ymax as 20. Graph Range -170-- sc1:10 Ymin:U max:20 scl: 2 riitrinrncg Next, specify the number of bars by increasing the number of value memories. Since we have 11 ranks, we should increase the number of memories by 11. If you skip this step, an error occurs when you try to draw the graph. • EDO Crl Program 0 Formula 65 F-Memory 0 Memory 39 Data 0 23890 Bytes Free firrcrTICUPRIEIEI Now clear the statistical memory. gE(§coo Input the data.

Note, however that you can only perform this operation immediately after a bar graph is drawn on the display. To find the mode immediately after drawing the above bar graph.
