What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

What does a positive correlation in a scatterplot indicate?

Back

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

What does a negative correlation in a scatterplot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does no correlation mean in a scatterplot?

Back

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

How do you calculate the linear regression equation from data?

Back

The linear regression equation can be calculated using statistical methods to find the best-fitting line through the data points, typically in the form y = mx + b.

What is the initial price in a linear equation context?

Back

The initial price is the y-intercept of the linear equation, representing the starting value when the independent variable is zero.
