3. 9.1 Scatterplot: (add onto notes in comp book)
graph with points to shows the relationship between two sets of data
Outlier: a piece of data that falls outside of the data pattern
Gap: missing information in data
Cluster: when group of data is close together

4. # of siblings & # of pets
In class activity

5. Weak correlation: Strong Correlation:
In Comp Book:
Positive Correlation
(linear)
Negative Correlation
(linear)
No Correlation
Non-linear Correlation
The points lie close to a line. As x increases, y-increase.
The values in both data sets show no pattern.
The points lie in the shape of a curve.
The points lie close to a line. As x increases, y-decreases.
Weak correlation: Strong Correlation:

10. Own Your Own: Determining Relationships
Write positive correlation, negative correlation, nonlinear correlation, or no correlation to describe each relationship. Explain.

11. Own Your Own: Determining Relationships
Write positive correlation, negative correlation, nonlinear correlation, or no correlation to describe each relationship. Explain.
The graph shows that as area increases, population increases.
So the graph shows a positive correlation between the data sets.

12. Own Your Own: Determining Relationships
Write positive correlation, negative correlation, nonlinear correlation, or no correlation to describe each relationship. Explain.
The graph shows that as the length of string increases, frequency decreases.
So the graph shows a negative correlation between the data sets.
vps = vibrations per second

13. Own Your Own: Determining Relationships
Write positive correlation, negative correlation, nonlinear correlation, or no correlation to describe each relationship. Explain.
Temperature Attendance
The graph shows a positive correlation.

14. Own Your Own: Determining Relationships
Write positive correlation, negative correlation, nonlinear correlation, or no correlation to describe each relationship. Explain.
negative correlation; as age increases, attendance decreases.
