Scatterplot Practice

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 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 can you identify a positive correlation in a scatterplot?

Back

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

Front

What is the purpose of a scatterplot?

Back

The purpose of a scatterplot is to visually represent the relationship between two variables and to identify trends or patterns.

Front

What type of relationship is indicated by a scatterplot with points scattered randomly?

Back

A scatterplot with points scattered randomly indicates no relationship between the variables.

Front

What is an example of a positive correlation in real life?

Back

An example of a positive correlation is the relationship between study time and test scores; generally, more study time leads to higher scores.

Front

What is an example of a negative correlation in real life?

Back

An example of a negative correlation is the relationship between the age of a car and its value; as the car gets older, its value typically decreases.
