4.1.6 - Quick Check: Scatter Plots

1 answer

It seems like you're looking for help with scatter plots, possibly in a specific context like a lesson or assignment. Scatter plots are used to visualize the relationship between two quantitative variables. Each point on the plot represents an observation in the dataset.

Here are some key points to consider when working with scatter plots:

  1. Axes: On a scatter plot, the x-axis typically represents the independent variable, while the y-axis represents the dependent variable.

  2. Trend: The overall direction of the points can indicate the relationship between the variables:

    • Positive correlation: As one variable increases, the other variable also increases.
    • Negative correlation: As one variable increases, the other variable decreases.
    • No correlation: No discernible pattern or relationship between the variables.
  3. Outliers: Points that fall far away from the general trend can be considered outliers. They can significantly affect the interpretation of the relationship between the variables.

  4. Line of Best Fit: In many cases, a line of best fit may be drawn to summarize the trend observed in the scatter plot.
