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 that there is no apparent relationship between the two variables; changes in one do not predict changes in the other.

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation can be identified by a pattern where data points slope upwards from left to right.

Front

How can you identify a negative correlation in a scatterplot?

Back

A negative correlation can be identified by a pattern where data points slope downwards from left to right.

Front

What is the purpose of using scatterplots?

Back

Scatterplots are used to visually represent the relationship between two variables and to identify trends, patterns, or correlations.

Front

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

Back

A cluster of points indicates that there is a concentration of data points in a specific area, suggesting a potential relationship between the variables.

Front

What is the significance of outliers in a scatterplot?

Back

Outliers are data points that fall far away from the general pattern of the data, which can indicate anomalies or errors in data collection.

Front

What is the x-axis in a scatterplot?

Back

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