What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

What does a positive correlation indicate in a scatterplot?

Back

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

Front

What does a negative correlation indicate in a scatterplot?

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 variable do not predict changes in the other.

Front

How do you identify a positive correlation in a scatterplot?

Back

In a positive correlation, the points on the scatterplot slope upwards from left to right.

Front

How do you identify a negative correlation in a scatterplot?

Back

In a negative correlation, the points on the scatterplot slope downwards from left to right.

Front

What is the purpose of plotting points on a coordinate plane?

Back

Plotting points on a coordinate plane helps visualize the relationship 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

What does the term 'outlier' mean in the context of scatterplots?

Back

An outlier is a data point that differs significantly from other observations in the dataset.
