3.2 NotesMeasure of CenterA measure of center is a value at the center ormiddle of a data set.Mean (or Arithmetic Mean)The mean (or arithmetic mean) of a set of datais the measure of center found by adding all ofthe data values and dividing the total by thenumber of data values.Important Properties of the MeanSample means drawn from the same populationtend to vary less than other measures of center.The mean of a data set uses every data value.A disadvantage of the mean is that just oneextreme value (outlier) can change the value ofthe mean substantially. (Using the followingdefinition, we say that the mean is not resistant.)ResistantA statistic is resistant if the presence ofextreme values (outliers) does not cause it tochange very much.Notationidenotes the sum of a set of data values.x is the variable usually used torepresent the individual data values.n represents the number of data valuesin a sample.
