Scatterplots

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 linear relationship in a scatterplot look like?

Back

A linear relationship in a scatterplot appears as a straight line, indicating that as one variable increases, the other variable tends to increase or decrease in a consistent manner.

Front

What are coordinates in a scatterplot?

Back

Coordinates in a scatterplot are pairs of values (x, y) that represent the position of a point on the graph, where 'x' is the value on the horizontal axis and 'y' is the value on the vertical axis.

Front

What is an outlier in a scatterplot?

Back

An outlier is a point that is far outside the main cluster of points in a scatterplot, which may indicate an unusual observation.

Front

What does positive correlation mean in a scatterplot?

Back

Positive correlation means that as one variable increases, the other variable also tends to increase, resulting in a scatterplot that slopes upwards.

Front

What does negative correlation mean in a scatterplot?

Back

Negative correlation means that as one variable increases, the other variable tends to decrease, resulting in a scatterplot that slopes downwards.

Front

What does no correlation mean in a scatterplot?

Back

No correlation means there is no apparent relationship between the two variables, and the points in the scatterplot are scattered randomly.

Front

How can you identify an outlier in a scatterplot?

Back

An outlier can be identified as a point that is significantly distant from the other points in the scatterplot, often lying far away from the main cluster.

Front

What is the purpose of a scatterplot?

Back

The purpose of a scatterplot is to visually represent the relationship between two quantitative variables and to identify patterns, trends, or outliers.

Front

What is the x-axis in a scatterplot?

Back

The x-axis is the horizontal axis in a scatterplot that typically represents the independent variable.
