8th STAAR 5d (scatterplot predictions)

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 axis.

Front

How can you use a scatterplot to make predictions?

Back

You can use a scatterplot to make predictions by observing the trend of the data points and estimating the value of one variable based on the value of another.

Front

What does a positive correlation in a scatterplot 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 scatterplot indicate?

Back

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

Front

What does it mean if the points in a scatterplot are widely spread out?

Back

If the points are widely spread out, it indicates a weak correlation between the two variables.

Front

What does it mean if the points in a scatterplot are closely clustered together?

Back

If the points are closely clustered together, it indicates a strong correlation between the two variables.

Front

What is the purpose of the x-axis in a scatterplot?

Back

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

Front

What is the purpose of the y-axis in a scatterplot?

Back

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

Front

How do you identify outliers in a scatterplot?

Back

Outliers are data points that fall far away from the general trend of the other points in the scatterplot.

Front

What is interpolation in the context of scatterplots?

Back

Interpolation is the process of estimating a value within the range of the data points in a scatterplot.
