Scatterplots

Front

What is a scatterplot?

Back

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

Front

What does a linear relationship in a scatterplot indicate?

Back

A linear relationship indicates that as one variable increases or decreases, the other variable tends to do the same in a consistent manner.

Front

What does it mean if a scatterplot shows no relationship?

Back

It means that there is no discernible pattern or correlation between the two variables being plotted.

Front

What is a positive correlation in a scatterplot?

Back

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

Front

What is a negative correlation in a scatterplot?

Back

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

Front

What is a weak correlation?

Back

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

Front

What is a strong correlation?

Back

A strong correlation indicates a clear and consistent relationship between the two variables, allowing for reliable predictions.

Front

How can you predict values using a scatterplot?

Back

You can predict values by observing the trend in the scatterplot and estimating where a new data point would fall based on the existing data.

Front

What does it mean if a scatterplot has a cluster of points?

Back

A cluster of points indicates that there is a group of data points that share similar values for the two variables.

Front

What is the purpose of using scatterplots in data analysis?

Back

Scatterplots are used to visually assess the relationship between two variables, helping to identify trends, correlations, and outliers.
