For the following data set, the box in a box-and-whisker plot is drawn between which two numbers? 23, 23, 6, 21, 6, 43, 50, 37, 21, 16, 42
Between 16 and 42
The box begins with Q1 or the 25th percentile. If you rank the data from low to high, determine Q1=16 . Q1 is the midpoint of the numbers below the median.
The box ends at Q3 or the 75th percentile. Q3= 42. Similarly, Q3 is the midpoint of the numbers above the median.
Hope that helped
