Scatter plots and LOBF

Front

What is a scatter plot?

Back

A graph that shows the relationship of two data sets.

Front

What does a positive correlation indicate in a scatter plot?

Back

As one variable increases, the other variable also increases.

Front

What does a negative correlation indicate in a scatter plot?

Back

As one variable increases, the other variable decreases.

Front

What does 'no correlation' mean in the context of a scatter plot?

Back

There is no discernible relationship between the two variables.

Front

How can you determine the type of correlation from a scatter plot?

Back

By observing the direction of the points: upward slope indicates positive, downward slope indicates negative, and random distribution indicates no correlation.

Front

What is the Line of Best Fit (LOBF)?

Back

A straight line that best represents the data on a scatter plot, showing the trend of the data.

Front

How do you use the Line of Best Fit to make predictions?

Back

You can estimate the value of one variable based on the value of another by finding the corresponding point on the LOBF.

Front

What is the purpose of creating a scatter plot?

Back

To visually display the relationship between two quantitative variables.

Front

What type of data is best represented in a scatter plot?

Back

Quantitative data for two variables.

Front

If a scatter plot shows a downward trend, what type of correlation is present?

Back

Negative correlation.
