Question A is asking: Considering the distribution shape (i.e skewed left, right, or symmetrical), what measure of center would be used? Explain why that measure of center would be used.
Question B is asking: What measure of variability (or change, i.e range, interquartile range, or standard deviation) would be used for this graph? Explain why this measure would be used.
Let the second score = x
⇒ second score = x
<span>the first is 14 points more than the second
</span>⇒ first score = x + 14
<span>the sum of the first two is 6 more than twice the third
</span>⇒ third score = 1/2 (x + x + 14 - 6) = x + 4
<span>The sum of a student's three score is 246
</span>⇒ x + (x + 14) + (x + 4) = 246
<span>
Solve x:
</span>x + x + 14 + x + 4 = 246
3x + 18 = 246
3x = 228
x = 76
second score = x = 76
first score = x + 14 = 76 + 14 = 90
