P2 CATEGORICAL VS NUMERICAL Categorical (qualitative) categories Eye color Food Months Numerical (quantitative) Numbers Temperature Age Height

PG. 349

P3 “ALL ABOUT THAT DOT/LINE PLOT”  On a number line  Uses or x to show frequency  Used to graph numerical data

Mean- Median- Mode- Range- Number of people that live in your home

P4 “ALL ABOUT THAT STEM-AND-LEAF”  Displays data organized by place value  Leaf: last digit of the number (goes to the right on the table)  Stem: first digit or digits (goes on the left)  Separated by vertical line Ex: Number of minutes to get ready this morning Key 2 3=23

Mean – Median- Mode- Range-

P5 DESCRIBE DATA: SHAPE, CENTER, SPREAD SHAPECENTERSPREADSHAPECENTERSPREAD Mean and Median measure center, depends on the distribution of data Is the data symmetrical? Yes=mean No=median Range

P6 “IT’S ALL ABOUT THAT SHAPE” (TURN PAGE LONG WAY SO PICTURES WILL FIT)

P7 “ALL ABOUT THAT BOX PLOT”  Organizes data into four parts (quartiles)  Use the minimum, Q1, median, Q3, and maximum to create the four parts  Q1=quartile 1= median of lower half of data  Q3=quartile 3=median of upper half of data  Box= created with Q1, Q3, line through median  “Whiskers”= connect box to the min and max of data

P8 “ALL ABOUT THAT BOX PLOT” Make a Box plot using the following data: 2, 5, 3, 3, 4, 1, 6, 2, 2 Min= Q1= Median= Q3= Max=

P9 “ALL ABOUT THAT IQR” IQR = Interquartile Range = Q3-Q1

P10 “ALL ABOUT THAT OUTLIER” Outliers are observations (data) that do not fit the overall pattern of the data set. Outlier affects the Mean If the outlier is larger then majority of the data then the Mean will seem larger (skewed right) If the outlier is smaller then majority if the data then the Mean will seem smaller (skewed left) Continued…..
