Answer:
True
Step-by-step explanation:
Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.

First we find the mean (average)
(90 + 82 + 88 + 78 + 93) / 5 = 431/5 = 86.2
now we find the absolute value of the difference of the data points and the mean
90 - 86.2 = 3.8....| 3.8 | = 3.8
82 - 86.2 = -4.2...| -4.2 | = 4.2
88 - 86.2 = 1.8....| 1.8 | = 1.8
78 - 86.2 = -8.2 | -8.2| = 8.2
93 - 86.2 = 6.8....| 6.8| = 6.8
now we find the mean (average) of those values
(3.8 + 4.2 + 1.8 + 8.2 + 6.8) / 5 = 24.8 / 5 = 4.96 <== the MAD
