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
