Scatterplots

Front

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.

Front

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.

Front

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 apparent relationship between the two variables; changes in one do not predict changes in the other.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatterplot, showing the general direction of the data points.

Front

How can you use a scatterplot to make predictions?

Back

You can use a scatterplot to make predictions by finding the line of best fit and using it to estimate values for one variable based on the other.

Front

What is the purpose of analyzing scatterplots?

Back

The purpose of analyzing scatterplots is to identify relationships, trends, and patterns between two variables.

Front

What is the x-axis in a scatterplot?

Back

The x-axis is the horizontal axis that typically represents the independent variable.

Front

What is the y-axis in a scatterplot?

Back

The y-axis is the vertical axis that typically represents the dependent variable.

Front

How do you determine the strength of a correlation in a scatterplot?

Back

The strength of a correlation can be determined by how closely the data points cluster around the line of best fit.
