Algebra 1 - Scatter Plots and Trend Lines

Scatter Plots and Trend Lines

• A scatter plot is utilized to visualize relationships between two numerical data sets.
• The scatter plot can indicate trends, clustering, or outliers within the data.
• Each point on the scatter plot represents a pair of values from the two data sets.

Trend Lines

• A trend line is a graphical representation added to a scatter plot to highlight correlation.
• It helps to summarize the data and make predictions based on the visualized trend.
• The slope of the trend line indicates the direction and strength of the relationship.

Correlation

• Correlation defines the degree to which two variables are associated or related.
• Positive correlation implies that as one variable increases, the other does too, while negative correlation indicates an inverse relationship.
• Correlation does not imply causation; it only indicates that a relationship exists between the data sets.
