Question

Make a box of whisker plot for the data what is the upper quartile value 42,48,43,65,58,47,60,56,52,64,51,66,56,62

Answer 1

First, you would want to reorder the numbers from least to greatest.
42,43,47,48,51,52,56,56,58,60,62,64,65,66
Then find the median which is 56
Next add all upper quartile numbers so 56+58+60+62+64+65+66=431
Last divide the sum of the upper quartile by the median to get the upper quartile value. 431/56= 7.69642857
