Scatter Plots TEKS 8.11A & 8.5C

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 positive correlation in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

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

Front

What does no correlation mean in a scatter plot?

Back

No correlation means there is no apparent relationship between the two variables; changes in one do not affect the other.

Front

How can you identify a linear relationship in a scatter plot?

Back

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

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, correlations, or patterns.

Front

What does the slope of a line in a scatter plot represent?

Back

The slope represents the rate of change between the two variables; a steeper slope indicates a stronger relationship.

Front

What is the independent variable in a scatter plot?

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 scatter plot?

Back

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

Front

How do you interpret the data points in a scatter plot?

Back

Data points represent individual observations; their position indicates the values of the two variables being compared.
