Types of Scatter Plot Association

Front

What is a Positive Association in a scatter plot?

Back

A positive association occurs when two variables increase or decrease together. For example, as the amount of time spent studying increases, test scores tend to increase.

Front

What is a Negative Association in a scatter plot?

Back

A negative association occurs when one variable increases while the other decreases. For example, as the number of ice cubes in a drink increases, the temperature of the drink tends to decrease.

Front

What does No Association mean in a scatter plot?

Back

No association means that there is no discernible relationship between the two variables. For example, the number of colors in a painting and the cost of the painting may not be related.

Front

Example of Positive Association: Time spent reading vs. Pages read.

Back

As the time spent reading increases, the number of pages read also increases.

Front

Example of Negative Association: Amount of fertilizer vs. Number of weeds.

Back

As the amount of fertilizer used increases, the number of weeds in the garden tends to decrease.

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

Front

How do you interpret a scatter plot with a positive association?

Back

In a scatter plot with a positive association, the points trend upwards from left to right, indicating that as one variable increases, the other variable also increases.

Front

How do you interpret a scatter plot with a negative association?

Back

In a scatter plot with a negative association, the points trend downwards from left to right, indicating that as one variable increases, the other variable decreases.

Front

What is the purpose of using scatter plots?

Back

Scatter plots are used to visually represent the relationship between two variables, helping to identify patterns, trends, and correlations.

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or none.
