Scatter Plots

Bell Work

1.What is correlation ?

2.In your own words explain what is the difference between a positive
correlation and negative correlation.

3.What is a negative correlation?

OBJ and DOL

OBJ: I can learn about scatter plot graphs.

DOL: Given 6 questions and two groups of data, I can create and
analyze scatter plots graphs by determining the correlation between two
variables with 100% accuracy.

Let’s Review

• Correlation: to describe and determine the

relationship or connection between 2 variables

• Positive correlation: both variables are increasing

(both going UP)

• Negative correlation: 1 variable is increasing, and

1 variable is decreasing (one going UP one going
DOWN)

• No correlation: there is no relationship or

connection between the variables

Scatter plots

Scatter plot: a graph with multiple
points that shows the relationship
between 2 sets of data

● The table shows the numbers of

losses y a gamer has x weeks after
getting a new video game. Draw a
scatter plot using the following data.
Remember to add labels and numbers
to the x and y axis.
