Scatterplot Practice

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 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 discernible relationship between the two variables; changes in one do not affect the other.

Front

How can you identify a linear relationship in a scatterplot?

Back

A linear relationship can be identified if the points in the scatterplot form a straight line or a pattern that resembles a straight line.

Front

What is the purpose of using scatterplots in data analysis?

Back

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

Front

What is the independent variable in a scatterplot?

Back

The independent variable is the variable that is manipulated or changed, typically plotted on the x-axis.

Front

What is the dependent variable in a scatterplot?

Back

The dependent variable is the variable that is measured or observed, typically plotted on the y-axis.

Front

How do you make predictions using a scatterplot?

Back

Predictions can be made by identifying the trend in the scatterplot and estimating the value of the dependent variable based on the independent variable.

Front

What is the significance of the slope in a scatterplot?

Back

The slope indicates the direction and steepness of the relationship between the two variables; a steeper slope indicates a stronger relationship.
