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.
