Front

What is a scatter plot?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable decreases.

Front

What does a positive correlation in a scatter plot indicate?

Back

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

Front

What does it mean if a scatter plot has no correlation?

Back

It means that there is no predictable pattern between the two variables.

Front

How can you identify a positive correlation in a scatter plot?

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 scatter plot?

Back

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

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables and to identify trends or correlations.

Front

What type of correlation exists between the outside temperature and the amount of layers you wear?

Back

Negative correlation.

Front

If a scatter plot shows points scattered randomly, what can be inferred?

Back

It can be inferred that there is no correlation between the variables.

Front

What is an ordered pair in the context of scatter plots?

Back

An ordered pair is a pair of numbers that represent the coordinates of a point on the scatter plot, typically written as (x, y).
