Question: Find the median from the stem-and-leaf plot.
A ) 57 B ) 119 C ) 62 D ) 59.5
Steps to derive
1 The data values from the stem-and-leaf plot are 40, 41, 43, 45, 52, 54, 56, 57, 62, 62, 63, 63, 65, 75, 75, and 76. [Attach each leaf to the corresponding stem.]
2 Median is the middle value in an ordered data set.
3 The data set contains 16 data values, 57 and 62 are the middle numbers.
4 Median = 57+622 = 59.5
5 So, median of the given stem-and-leaf plot is 59.5
