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

Explanation:

• Positive/Negative: As the average years of education increase, the average salary also increases. So, there is a positive relationship.
• Linear/Non - linear: The data points seem to follow a trend that can be approximated by a straight - line (the orange line). So, it has a linear trend.
• Outliers: There is an outlier. When the average years of education is around 15 (approximate value from the x - axis), the average salary is much lower than the trend. Let's assume the x - value (average years of education) is \(x = 15\) and the y - value (average salary) is \(y=15000\) (approximate from the graph, actual values may vary depending on exact graph scale).
• What the graph tells: It implies that, in general, more years of education are associated with higher salaries, but there can be some exceptional cases (the outlier) where this relationship does not hold as strongly.

Answer:

• Positive relationship.
• Linear trend.
• Outlier at (approx) \(x = 15\), \(y = 15000\).
• More education is generally linked to higher salary, but with exceptions.
