P4 “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

P5 “All about that stem-and-leaf” Key 2 3=23 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

Mean – Median- Mode- Range-

Is the data symmetrical? P6 Describe data: shape, center, spread S H A P E C N T R D Is the data symmetrical? Yes=mean No=median Mean and Median measure center, depends on the distribution of data Range

P7 “it’s all about that shape” (Turn page long way so pictures will fit)

P8 “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

P9 “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=

P10 “All About that IQR” IQR = Interquartile Range = Q3-Q1

P11 “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….. Picture

P12 “All about that histogram” Bar Graph Histogram

P13 “All about that histogram” Graphs numerical data in intervals that show the frequency within that interval Bars ALWAYS touch Use a frequency table to gather data before graphing. Describe the shape and spread of the graphs below

P14 “All about that Relative frequency” Relative Frequency is the percent value of a category. Convert fraction, part/whole, into a percent

P16 “all about that variable”

P17 “all about that variable”
