Question

Allie was trying to describe point A's influence on r in the scatterplot below.

y
2
15
30
45
60
75
-20
-40-
-60
Allie said, "Point A is far to the right compared to the rest of the points, so it's an outlier. Removing it would
weaken the overall pattern, so r would get closer to 0.
What is the first mistake in Allie's response?

Answer 1

Answer: point A is clearly not an outlier

Step-by-step explanation:

The answer is that the first mistake in Allie's answer is that point A is clearly not an outlier as it falls near the regression line and is relatively close to the surrounding points.
