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

# of siblings & # of pets In class activity

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:

Example 2b Describe the relationship between the data. Identify any outliers, gaps, or clusters. Number of Farm Workers Relationship: Outliers: Gaps: Clusters: 1940 1960 1980 2000 10,000 8,000 6,000 4,000 2,000 Number (in thousands)‏

Example 3b Describe the relationship between the data. Identify any outliers, gaps, or clusters. Relationship: Outliers: Gaps: Clusters:

Example 4 Describe the relationship between the data. Identify any outliers, gaps, or clusters. Television size and price Relationship: Outliers: Gaps: Clusters:

Example 5 Describe the relationship between the data. Identify any outliers, gaps, or clusters. Age and number of pets owned Relationship: Outliers: Gaps: Clusters:

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

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.

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

Own Your Own: Determining Relationships Write positive correlation, negative correlation, nonlinear correlation, or no correlation to describe each relationship. Explain. Temperature Attendance 70 100 80 350 75 250 85 400 74 200 82 375 72 260 The graph shows a positive correlation.

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.
