What does 'no correlation' mean in the context of a scatter plot?

Back

No correlation means that there is no discernible relationship between the two variables; changes in one variable do not predict changes in the other.

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, minimizing the distance between the line and all the points.

How can you identify an outlier in a scatter plot?

Back

An outlier is a point that lies far away from the other points in the scatter plot, indicating it does not fit the general trend of the data.

What is a weak correlation?

Back

A weak correlation indicates that there is a relationship between the variables, but it is not strong enough to make reliable predictions.

What is the purpose of using a trend line in a scatter plot?

Back

A trend line helps to summarize the relationship between the variables and can be used to make predictions based on the data.

How do you interpret the slope of a trend line?

Back

The slope of a trend line indicates the rate of change of the dependent variable for each unit change in the independent variable.
