Scatter plot and line of best fit

Front

What is a scatter plot?

Back

A scatter plot 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 is the purpose of a line of best fit?

Back

The line of best fit is used to summarize the relationship between the variables in a scatter plot and to make predictions based on the data.

Front

What is the first step in writing an equation of a line of fit?

Back

Make a scatter plot of the data.

Front

How can a line of fit be used in a scatter plot?

Back

To predict future outcomes.

Front

What does a scatter plot with no correlation look like?

Back

Points are scattered randomly with no discernible pattern.

Front

What is the independent variable in a scatter plot comparing students' heights to their shoe sizes?

Back

Shoe size.

Front

What is a dependent variable in a scatter plot?

Back

The dependent variable is the one that is being measured or tested in an experiment, often plotted on the y-axis.

Front

What is an outlier in the context of scatter plots?

Back

A data point that lies far away from the other data points.

Front

What does a positive correlation in a scatter plot indicate?

Back

As one variable increases, the other variable also tends to increase.

Front

What does a negative correlation in a scatter plot indicate?

Back

As one variable increases, the other variable tends to decrease.
