A graph with points to show the relationship between two sets of data
Scatter plot
The horizontal axis on a coordinate plane
The X axis
Describe this association.
Strong, Positive, Linear
Using the scatterplot below, come up with a reasonable estimate for y when x = 5
About 20 or 21.
5+5
10
a set of closely grouped data
Cluster
How slope is measured
Rise/Run
change in y/change in x
y-y/x-x
Describe this association
Weak, Negative, Linear
Using the scatterplot below, come up with a reasonable estimate for x when y = 60
Around 19 or 20.
(80 / 2)+ 2
42
A data point that is very different from the rest of the data
outlier
Point A on a triangle is at (2, 3) and translated using the rule (x + 3, y - 2). The new Point A is located
(5, 1)
Describe the association:
No association, with an outlier
Using the scatterplot below, come up with a reasonable estimate for y when x = 13
Somewhere from 40-45
54 + 47 - 3
98
A line on a scatter plot that helps show the association between data sets more clearly
Trend line
Is this a linear function?
4x = 3(y-1)
Yes
