Draw the box-plot diagram for the given data.Data 80, 90, 85, 70, 60, 90, 95, 60, 75, 70, 80, 85, 90, 85, 95, 20, 75, 80, 85, 70

Here is the box-plot diagram for the given data:

        20                  *
        60      *           *
        70  *  |     *     |
        75     |           |
        80  *  |  *     *  |
        85  *  |  *  *  *  |
        90  *  |     *  *  |
        95  *  |        *  |
             --|--|--|--|--
                1  2  3  4

In this diagram, the box extends from the lower quartile (Q1) to the upper quartile (Q3), with a line at the median (Q2). The whiskers extend from the box to the minimum and maximum values within 1.5 times the interquartile range (IQR). Any data points outside of this range are shown as individual points (outliers).
