UNIT 6.1 & 6.2 - PRACTICE FINAL

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What does a positive relationship in a scatterplot indicate?

Back

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

Front

What does a negative relationship in a scatterplot indicate?

Back

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

Front

What is a linear relationship?

Back

A linear relationship is a relationship that can be represented by a straight line on a graph.

Front

What is a nonlinear relationship?

Back

A nonlinear relationship is a relationship that cannot be represented by a straight line; it may curve or change direction.

Front

What is an association in a graph?

Back

An association in a graph refers to the relationship between two variables, which can be positive, negative, or none.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatterplot, minimizing the distance between the line and the data points.

Front

How can you determine if a line is an accurate line of best fit?

Back

You can determine accuracy by checking how closely the line follows the trend of the data points and how well it predicts values.

Front

What does it mean if there is no relationship between two variables?

Back

It means that changes in one variable do not affect the other variable; the data points are scattered without any discernible pattern.

Front

What is the purpose of analyzing scatterplots?

Back

The purpose is to identify relationships, trends, and patterns between two quantitative variables.
