4. Poster Projects Chapter 3 summary
Use the class data to analyze class trends
Note: you may need to change quantitative data to categorical data by grouping
Create an easy to follow poster with a partner with the following categorical data displays:
1) Relative frequency table (with count and %)
2) Bar chart
3) Pie chart
4) Contingency table (choose something interesting)
5) Segmented bar chart
6) a sentence about the contingency table/segmented bar chart describing the trend and association of the variables (independence)
7) a sentence each describing a marginal distribution and a conditional distribution
Label graphs appropriately!

5. Homework Finish posters Study Chapter 2/3 Quiz

8. Objective
SWBAT show mastery in understanding context, distinguishing between quantitative and categorical data, and reading contingency tables
SWBAT identify, read, and create the four quantitative displays/graphs

9. Quiz
20 min

10. Independence and Distribution Review
Refer to your data table of quiz scores
Let’s make/report
1) a contingency table
2) a marginal distribution
3) a conditional distribution
4) variable dependence
Right now, we know how to make this into a graph…how would you make this into a graph? What graph would you use??

11. Data Displays Refer back to your quiz score data…
If I want to create a display of just your scores, how would I do that?
Note: what type of data are we presenting? Categorical or quantitative?

12. Displaying Quantitative Data
1) stem and leaf
2) dot plot
3) histogram
Relative frequency histogram
4) time plot

13. Stem and Leaf

14. Stem and Leaf
If I told you that this was the amount of time students took to solve math problems:
16,50,54,42,45,43,20
22,31,55,30,34,56,25
How would you display
this with stem and leaf?

15. Use Quiz Data
Make a stem and leaf chart of the class quiz data

16. Dot Plot Essentially a bar chart…
Now make a dot plot for the quiz grades of this class…

17. Histogram frequency and relative frequency
nlk
NOW MAKE A HISTOGRAM OF YOUR CLASS QUIZ SCORES

18. Making a dot plot or Histogram
Vertical axis: ALWAYS FREQUENCY
(or relative frequency- %s)
Horizontal axis: ALWAYS NUMBER LINE
Determine the range of values for axes
Determine the bin width
Add a dot or bar height according to data!

19. Time Plot

21. Practice-RACE We are going to practice displaying data.
You will each receive a page of problems with data. Everyone will begin with problem one.
Everyone will be told the first task (a certain type of graph) to perform with the data of problem one.
When you finish the task, raise your hand to be checked and get your task for the second problem with a different set of data…and so on
As soon as you receive the next task you may begin that task. The first to complete all tasks, wins. Work INDIVIDUALLY and SILENTLY
