2. the standard deviation assuming the data set is a sample from a
population, sx;
3. the standard deviation assuming the data set represents the entire
population, σx;
4. the sum of the data values, ∑x;
5. the sum of the squared data values, ∑x2;
Press ▼five times to see more of the statistics.
6. the number of values in the data set, n;
7. the minimum value in the data set, xmin;
8. the first quartile (25th percentile), Q1;
9. the median (50th percentile), Med;
10. the third quartile (75th percentile), Q3; and
Press ▼one more time to see the final statistic.
11. the maximum value in the data set, xmax.

DEL ENTER . Set the graph to a broken line graph by pressing
STAT PLOT B (B.L.) 3(Broken).
4. In our example, the smallest value is 13 and the largest value is 41.
The logical intervals for the data set would be 10-19 (tens), 20-29 (twenties),
30-39 (thirties), and 40-49 (forties). To set this viewing window, press
WINDOW and set the horizontal axis to 10 < x< 50 with Xscl = 10.
