Scatterplots and Two Way Tables CHECK

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 grid.

Front

What does a positive association in a scatterplot indicate?

Back

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

Front

What does a negative association in a scatterplot indicate?

Back

A negative association indicates that as one variable increases, the other variable tends to decrease.

Front

What does 'no association' mean in the context of scatterplots?

Back

'No association' means that there is no discernible relationship between the two variables; changes in one do not affect the other.

Front

What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of two categorical variables.

Front

How do you calculate relative frequency from a two-way table?

Back

Relative frequency is calculated by dividing the frequency of a specific category by the total number of observations.

Front

What is the purpose of using scatterplots?

Back

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

Front

What is a linear association?

Back

A linear association is a relationship between two variables that can be represented by a straight line on a scatterplot.

Front

What is a nonlinear association?

Back

A nonlinear association is a relationship between two variables that does not follow a straight line; it may curve or have a more complex pattern.

Front

What does it mean if a scatterplot shows a constant relationship?

Back

A constant relationship means that the value of one variable does not change regardless of the value of the other variable.
