Unit Overview: Scatter Plots and Data
We are now starting the chapter that covers scatter plots. Scatter plots compare two sets of numeric data
using a dot or box plots by comparing shape, center, and spread. The data is used from a random sample
to make inferences about a population or to make predictions.
Lesson 1: Scatter Plot and Association
Objective: Be able to do this by the end of this lesson:
❖ Identify if the data is:
linear or non-linear
positive or negative
strong or weak
Let’s begin:
1. Read and memorize the following:

2. Now, let’s look at Suzie’s survey:
Count the dots!
Did the number of
items purchased
increase or decrease?
Did the total money
spent increase or
decrease?
3. Here are some more details that you should memorize:
4. Using the three phrases above (positive association, negative association, and no association),

5. Read and memorize:
6. Label the graphs below as (a) POSITIVE, NEGATIVE, or NO ASSOCIATION, (b) STRONG or
WEAK, and (c) LINEAR or NON-LINEAR. (Note: some are already answered).

Lesson 2: Constructing Scatter Plots
Objective: Be able to construct scatter plots with given data and identify if the data is linear or non-
linear, strong or weak, and positive or negative.
➢ Today we will start our work with Jared’s awesome basketball team! I plotted the dot when
Jacob stood 14 ft away from the basket and made 4 shots. (He might need extra practice)!
Read the story and plot the additional points. Then, answer the question by stating if they are
linear or non-linear, strong or weak, and positive or negative.

➢ Next, study the following information and answer the questions.
Yep, he
does need
more
practice!
➢ Try these on your own.

Lesson 3: Scatter Plots and Trend Lines
Objective: Be able to identify scatter plots with a linear relationship and write linear equations.
➢ Today we are going to jump right into the lesson. Study the meaning of “Trend Lines.”
➢ Below, one question is completed. Answer the remaining ones.
➢ The next step is to write the linear equations that fit the scatter plot. Yes, the slope and y-
intercept equation is back! This is a great review and preparation for Algebra 1.
