Scatterplot Intro

Front

What is a scatterplot?

Back

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

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

Front

What is the purpose of using scatterplots?

Back

Scatterplots are used to visually assess the relationship between two quantitative variables.

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation can be identified when the points on the scatterplot slope upwards from left to right.

Front

How can you identify a negative correlation in a scatterplot?

Back

A negative correlation can be identified when the points on the scatterplot slope downwards from left to right.

Front

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

Back

A cluster of points indicates that there is a strong relationship between the two variables in that area.

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that differs significantly from other observations in the dataset, which can affect the correlation.

What type of relationship does Graph D show?

Back

Graph D shows no relationship.
