What does a positive slope indicate in a scatter plot?

Back

A positive slope indicates that as one variable increases, the other variable also increases, showing a direct relationship.

What does a negative slope indicate in a scatter plot?

Back

A negative slope indicates that as one variable increases, the other variable decreases, showing an inverse relationship.

What does it mean if a scatter plot has no association?

Back

If a scatter plot has no association, it means there is no discernible relationship between the two variables, and the points are scattered randomly.

How can outliers affect the slope of a scatter plot?

Back

Outliers can significantly affect the slope of a scatter plot by skewing the overall trend, potentially leading to misleading interpretations of the relationship.

What is the formula for calculating the slope of a line in a scatter plot?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

What is the significance of the slope in a scatter plot?

Back

The slope indicates the strength and direction of the relationship between the two variables represented in the scatter plot.

What does a slope of 0 indicate in a scatter plot?

Back

A slope of 0 indicates that there is no change in the dependent variable as the independent variable changes, suggesting a horizontal line.

What is the role of the x-axis and y-axis in a scatter plot?

Back

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable, allowing for the visualization of their relationship.

Front

How can you identify a linear relationship in a scatter plot?

Back

A linear relationship can be identified if the points in the scatter plot form a pattern that resembles a straight line.
