1. Types of Graphs

2. FREQUENCY CHART A table that lists each data item with its frequency.

3. Frequency

4. LINE PLOT Used to display data by placing an “x” for each response along a number line.

5. BAR GRAPH A graph used when comparing amounts. (parts to parts)

6. LINE GRAPH A graph used to show changes over time.

7. HISTOGRAM A type of bar graph that displays the data in intervals.

8. WeeklyTV Viewing 60 40 Number of People 20 0-2 3-5 6-8 Hours

9. HISTOGRAM Calories of Soup-in-a-Cup

10. LINE PLOT The following grades were made on the last test. Display them in a line plot. 7 26 13 85 54 98 9

11. Items Sold at Football Game Concession Stand

12. CIRCLE GRAPH A graph used to show parts of a whole.

13. SCATTERPLOT A graph used to show that there is a relationship between two different sets of information.

14. Arm Span verses Height • Measure your height in inches • Measure the distance of your arm span. • Record the data in your graphing calculator in List 1 for arm span, List 2 for height.

15. Box and Whisker • Shows the distribution of data along a number line • Related to medians, which divide data into two equal parts • Good to make comparisons between items

16. Box and Whisker Plots 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

17. Measures of Variation • Are used to describe distribution of data.

18. Quartiles • Values that divide a set of data into four equal parts. • **Remember that the Median separates a set of data in two equal parts

19. Lower & Upper Quartiles • The median of the lower half of a set of data is the lower quartile or LG • The median of the upper half of a set of data is the upper quartile or UQ.

20. Interquartile Range • This is the range of the middle half of the data. It is the difference between the upper quartile and the lower quartile.

21. Outliers: data that is more than 1.5 times the value of the interquartile range beyond the quartiles

22. Box and Whisker Plots Interquartile Range Lower Quartile Upper Quartile 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

23. Four Color Activity for Box and Whisker Plots • Sort the four color cards into groups where you have a match of statistics, data, graph, conclusion. • Record your groups on the recording sheet.

24. Stem and Leaf Plot • Shows data items in order
