8. P4 “All about that dot/line plot”
On a number line
Uses • or x to show frequency
Used to graph numerical data

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

10. 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

11. Mean –
Median-
Mode-
Range-

12. 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

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

14. 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

15. 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=

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

17. 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)

18. P11 Continued

19. P12 “All about that histogram”
Bar Graph Histogram

20. 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

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

22. P16 “all about that variable”

23. P17 “all about that variable”
