identify and explain the relationship between the variables from the graph.
average years of education vs salary

Explanation:

• Positive/Negative: As years of education increase, salary generally increases, so it's positive.
• Linear/Non - linear: The trend line (the orange line) is approximately straight, so it has a linear trend.
• Outliers: The point at around 14 years of education with a very low salary (far below the trend line) is an outlier. Also, the point at 20 years of education with a very high salary (far above the trend line) is an outlier.
• What the Graph Tells: It shows that, in general, there is a positive linear relationship between average years of education and average salary, but there are some data points that deviate from this general trend.

Answer:

• The graph is positive.
• The graph has a linear trend.
• It contains outliers. For example, there is an outlier at approximately (14, 15000) (very low - salary for its education level) and (20, 80000) (very high - salary for its education level).
• The graph tells that there is a general positive linear association between average years of education and average salary, but there are individual data points that do not follow this exact pattern.
