The test scores from Mrs. Gray's Math class are shown below.

72, 73, 66, 71, 82, 85, 95, 85, 86, 89, 91, 92

Construct a box-and-whisker plot to display these data.

--65--70--75--80--85--90--95--100--

^what the graph looks like^

How would you solve this using a graphing calculator? My teacher told me to put the numbers in L1, which I did, then go to stat-> calc-> 1-var stats. That gave me a weird answer though.

    Box and whisker plot

    The box should contain the middle 50% of scores, from the first quartile to the third quartile, with the median labeled. The whiskers should extend from the two ends of the box to the values of the extreme high and low scores.

    I do not have a graphing calculator.
