What is a line of best fit?

Back

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

What is an outlier?

Back

An outlier is a data point that differs significantly from other observations in a dataset.

Front

How do you determine if a line is a line of best fit?

Back

A line is a line of best fit if it minimizes the distance between itself and all the data points, ideally passing through the center of the data.

Front

What is the purpose of using interpolation in data analysis?

Back

Interpolation is used to estimate unknown values within the range of a set of known data points.
