# Lesson 3

What a Point in a Scatter Plot Means

### Problem 1

Here is a table and a scatter plot that compares points per game to free throw attempts for a basketball team during a tournament.

player

free throw
attempts

points
player A 5.5 28.3
player B 2.1 18.6
player C 4.1 13.7
player D 1.6 10.6
player E 3.1 10.4
player F 1 5
player G 1.2 5
player H 0.7 4.7
player I 1.5 3.7
player J 1.5 3.5
player K 1.2 3.1
player L 0 1
player M 0 0.8
player N 0 0.6

1. Circle the point that represents the data for Player E.
2. What does the point $$(2.1,18.6)$$ represent?

3. In that same tournament, Player O on another team scored 14.3 points per game with 4.8 free throw attempts per game. Plot a point on the graph that shows this information.

### Problem 2

A:

Histogram

B:

C:

Dot plot

D:

Table

E:

Box plot

### Solution

(From Unit 6, Lesson 2.)

### Problem 3

A cylinder has a volume of $$36\pi$$ cm3 and height $$h$$. Complete this table for the volume of other cylinders with the same radius but different heights.

height (cm) volume (cm3)
$$h$$ $$36\pi$$
$$2h$$
$$5h$$
$$\frac h2$$
$$\frac h5$$
