Mean - answer✔Average, calculated by adding a series of elements in a data set together and
dividing by the total number in the series.
Outlier - answer✔An observation point that is statistically distant from the other observations in
the dataset.
Regression Line - answer✔The line of best fit to show the relationship between variables, the
one that minimizes distance from each data point to the line.
