Measuring the bat speed versus home runs hit for a baseball playerMeasuring the bat speed versus home runs hit for a baseball player.

The response variable is the (Bat Speed/Home Run Hits) and the explanatory variable is the (Bat Speed/Home Run Hits).

The scatterplot should be expected to have a (positive/negative) direction and be (curved/linear) with (small/a lot of) variation.

Explanation / Answer

The response variable is the Home Run Hits which are being measured and the explanatory variable is the (Bat Speed).

The scatterplot should be expected to have a (positive) direction becuase more the speed, farther the ball goes and be (curved) with (small) variation.
