Mean for population data:

mean =

the value of the sample mean 𝑥 varies from sample to sample

Sometimes a data set may contain a few very small or a few very large values. Such values are called

The mean is always the best measure of central tendency because it is heavily influenced by outliers.

The ......... is the value of the middle term in a data set that has been ranked in increasing order

sample median : The single middle value if 𝑛 is ........

median =

The mode is the value that occurs with the highest frequency in a data set.

One advantage of the mode is that it can be calculated

The .............. is a better measure when a data set includes outliers.

The mean is the most-used measure of central tendency, followed by the median

the mean, median, and mode are identical, and they lie at the center of the distribution.

The measures of central tendency, such as the mean, median, and mode, donot reveal the whole picture of the distribution of a data set

The mean, median, or mode by itself is usually a sufficient measure to reveal the shape of the distribution of a data set.

The measures that help us learn about the spread of a data set are called the measures of .......

The range is the simplest measure of dispersion to calculate

Range =
