Question

describe the slope of a trend line that models the data in a scatter plot with positive correlation. describe the slope of a trend line that models the data in a scatter plot with negative correlation

in a scatter plot with positive correlation, the slope of the trend line is
in a scatter plot with negative correlation, the slope of the trend line is

Explanation:

Step1: Understand positive correlation

In a positive correlation, as one variable increases, the other also increases. A trend line (like \(y = mx + b\)) for such data has a positive slope (\(m>0\)).

Step2: Understand negative correlation

In a negative correlation, as one variable increases, the other decreases. A trend line for such data has a negative slope (\(m < 0\)).

Answer:

In a scatter plot with positive correlation, the slope of the trend line is positive. In a scatter plot with negative correlation, the slope of the trend line is negative.
