Outliers in scatter plots
Outliers in scatter plots
What you'll learn
- Identify potential outliers in a scatter plot by visually inspecting the data points and recognizing those that deviate significantly from the overall trend with 80% accuracy.
- Explain how the presence of an outlier can affect the line of best fit (trend line) in a scatter plot, using specific examples from provided graphs in a written paragraph.
- Calculate the equation of the line of best fit for a scatter plot both with and without an identified outlier, and compare the resulting slopes and y-intercepts.
- Evaluate whether a given data point is a true outlier or simply represents natural variation within a dataset, justifying the decision with reasoning based on the context of the data and its potential impact on conclusions.
