+ Steps for Graphing on a Calculator Step 3:to see graph ZOOM  9:ZoomStat

+ Describing Data Numerically Measures of Center – mean, median Measures of Spread – range, interquartile range, standard deviation

+ Numerical Descriptions in a Calculator Step 1: STAT  Edit  Enter all data into L1 Step 2: STAT  CALC  1: 1-Var Stats = Mean S x = Standard Deviation 5 Number Summary: Min, Q1, Med, Q3, Max Range = Min – Max IQR = Q3 – Q1

+ Describing Distributions Shape Outliers Center Spread

+ 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 Outliers Center is the MEAN

+ Spread IF Outliers: Spread is the IQR IF NO Outliers Spread is the Standard Deviation and the Range
