Describing and Interpreting Scatter Plots Practice

Front

What is a negative correlation?

Back

A negative correlation is a relationship between two variables in which one variable increases as the other decreases. For example, as the outside temperature increases, the amount of layers you wear decreases.

Front

What is an outlier in a scatterplot?

Back

An outlier is a point that is far outside the main cluster of points/ordered pairs in a scatterplot, indicating an unusual observation.

Front

What does the x-axis represent in a scatterplot?

Back

The x-axis typically represents the independent variable. For example, in a scatterplot showing hours worked versus amount earned, the x-axis would represent 'Hours Worked'.

Front

What does the y-axis represent in a scatterplot?

Back

The y-axis typically represents the dependent variable. For example, in a scatterplot showing hours worked versus amount earned, the y-axis would represent 'Amount Earned in Dollars'.

Front

What type of relationship exists between height and weight in a positive correlation?

Back

In a positive correlation, as one variable increases, the other variable also increases. For example, generally, as height increases, weight tends to increase.

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What does it mean if there is no correlation between two variables?

Back

If there is no correlation, it means that changes in one variable do not predict changes in the other variable. The points in the scatterplot do not show any discernible pattern.

Front

How can you identify a positive correlation in a scatterplot?

Back

A positive correlation can be identified when the points in the scatterplot trend upwards from left to right, indicating that as one variable increases, the other variable also increases.

Front

How can you identify a negative correlation in a scatterplot?

Back

A negative correlation can be identified when the points in the scatterplot trend downwards from left to right, indicating that as one variable increases, the other variable decreases.

Front

What is the purpose of a scatterplot?

Back

The purpose of a scatterplot is to visually display the relationship between two quantitative variables, helping to identify trends, correlations, and outliers.
