Min=13 First quart=22 Median=32.5 Third quart=41 Maximum=61
Work Step by Step
You have the values:13,19,22,30,31,34,37,41,48,61. The minimum is the least value which is 13. The median is the middle value which is 31 and 34. Find the average between the two and that is the median. (31+34)/2=32.5.The median is 32.5 The maximum is the largest value which is 61. The first quartile is the middle value between the minimum and the median(13,19,22,30,32). The first quartile is 22. The third quartile is the middle value between the median and the maximum (34,37,41,48,61). The third quartile is 41. Use this to make a box and whisker plot.
