Scatterplot Predictions

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

What does a positive correlation on a scatterplot indicate?

Back

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

Front

What does a negative correlation on a scatterplot indicate?

Back

A negative correlation indicates that as one variable increases, the other variable decreases.

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatterplot, showing the trend of the data.

Front

How do you determine the line of best fit?

Back

The line of best fit can be determined by visually inspecting the scatterplot and drawing a line that minimizes the distance of all points from the line.

Front

What does it mean if there is no correlation in a scatterplot?

Back

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

Front

What is the purpose of using a scatterplot?

Back

Scatterplots are used to visualize the relationship between two quantitative variables and to identify trends, patterns, or correlations.

Front

How can you make predictions using a scatterplot?

Back

You can make predictions by locating a value on one axis and using the line of best fit to find the corresponding value on the other axis.

Front

What is an outlier in a scatterplot?

Back

An outlier is a data point that differs significantly from other observations in the dataset, often appearing far away from the trend.

Front

What does it mean if a scatterplot has a strong correlation?

Back

A strong correlation means that the points on the scatterplot are closely clustered around the line of best fit, indicating a strong relationship between the variables.
