Answer
Please see the image.
Minimum = 51
Maximum = 91
Median = 78
1st quartile = 61
3rd quartile = 85
Work Step by Step
$87, 52, 91, 66, 79, 56, 73, 90, 78, 51, 83$
$51, 52, 56, 66, 73, 78, 79, 83, 87, 90, 91$
minimum = 51
maximum = 91
$51, 52, 56, 66, 73, 78, 79, 83, 87, 90, 91$
$52, 56, 66, 73, 78, 79, 83, 87, 90$
$56, 66, 73, 78, 79, 83, 87$
$66, 73, 78, 79, 83$
$73, 78, 79$
$78$ = median
$51, 52, 56, 66, 73, 78$
$52, 56, 66, 73$
$56, 66$
$(56+66)/2 = 61$
$78, 79, 83, 87, 90, 91$
$79, 83, 87, 90$
$83, 87$
$(83+87)/2 = 85$
