+Describing Data Numerically

Measures of Center – mean, median

Measures of Spread – range, interquartile range, standard deviation

+Numerical Descriptions in a Calculator

= Mean

Sx = Standard Deviation

5 Number Summary: Min, Q1, Med, Q3, Max

Range = Min – Max

IQR = Q3 – Q1

+Shape

Mound shaped & symmetrical

Skewed left (extreme low values)

Skewed right (extreme high values)

Uniform

+Outliers

When you graph a boxplot on your graphing calculator; choose the boxplot that will show OUTLIERS, use the TRACE feature on your calculator to find outliers.

+Center

IF Outliers:Center is the MEDIAN

IF NO OutliersCenter is the MEAN

+Spread

IF Outliers:Spread is the IQR

IF NO OutliersSpread is the Standard Deviation and the Range
