Creating Scatter Plots

Front

What is a scatter plot?

Back

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

Front

What does the x-axis represent in a scatter plot?

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or changed.

Front

What does the y-axis represent in a scatter plot?

Back

The y-axis typically represents the dependent variable, which is the variable that is measured or observed.

Front

What is the purpose of a line of best fit in a scatter plot?

Back

The line of best fit is used to summarize the relationship between the variables and to make predictions based on the data.

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

Front

How can you determine the strength of a correlation in a scatter plot?

Back

The strength of a correlation can be determined by how closely the data points cluster around the line of best fit; tighter clusters indicate stronger correlations.

Front

What is an example of a situation that could be represented by a scatter plot?

Back

An example could be the relationship between hours studied and test scores, where each point represents a student's hours studied and their corresponding test score.

Front

What is the first step in creating a scatter plot?

Back

The first step is to collect and organize the data for the two variables you want to compare.
