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 plane.

Front

What does the x-axis represent in a scatterplot?

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 scatterplot?

Back

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

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 no correlation mean in a scatterplot?

Back

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

Front

How can you estimate a value using a scatterplot?

Back

You can estimate a value by locating the corresponding point on the scatterplot based on the known value of the independent variable.

Front

What is the purpose of using scatterplots in data analysis?

Back

Scatterplots are used to visually assess the relationship between two variables, identify trends, and make predictions.

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that lies significantly outside the range of the other data points, potentially indicating an anomaly.

Front

How can scatterplots help in making predictions?

Back

Scatterplots can help in making predictions by showing trends that can be used to estimate values for unknown data points.
