What is an OUTLIER in statistics?

Back

An outlier is a value that is significantly higher or lower than the other values in a data set.

How do you calculate the STANDARD DEVIATION of a data set?

Back

Standard deviation measures the amount of variation or dispersion in a set of values. It is calculated using the formula: √(Σ(xi - μ)² / N), where μ is the mean and N is the number of values.

Front

What is the MEAN of a data set?

Back

The mean is the average of all the values in a data set, calculated by dividing the sum of all values by the total number of values.

What is the MEDIAN of a data set?

Back

The median is the middle value when the data set is ordered from least to greatest. If there is an even number of values, the median is the average of the two middle numbers.
