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

- 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.
