What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatter plot, showing the trend of the data points.

What does a positive correlation indicate?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

What does it mean if there is no correlation between two variables?

Back

If there is no correlation, it means that there is no predictable relationship between the two variables.

How can you visually identify the line of best fit on a scatter plot?

Back

The line of best fit can be visually identified as the line that minimizes the distance between itself and all the data points on the scatter plot.

What is the purpose of the line of best fit in data analysis?

Back

The purpose of the line of best fit is to summarize the relationship between two variables and to make predictions based on that relationship.

What is a scatter plot?

Back

A scatter plot is a graph that displays values for typically two variables for a set of data, using Cartesian coordinates.

What does it mean if a scatter plot shows a linear relationship?

Back

A linear relationship means that the data points can be approximated by a straight line, indicating a consistent relationship between the variables.

What is the significance of the slope of the line of best fit?

Back

The slope of the line of best fit indicates the rate of change between the two variables; a steeper slope indicates a stronger relationship.

What is the difference between a strong correlation and a weak correlation?

Back

A strong correlation means the data points are closely clustered around the line of best fit, while a weak correlation means the points are more spread out.
