1. BAR GRAPH Bar Graph: Uses bars to show quantities or numbers for comparison

2. DATA Data: A collection of information used in graphs or charts for analysis. It can include numbers, measurements or facts.

3. FREQUENCY Digit Times on chart 1 1 2 4 3 4 4 3 5 5 6 4 7 3 8 1 9 3 Data: 2, 5, 6, 8, 2, 3, 4, 5, 7, 2, 9, 3, 5, 6, 7, 3, 4, 5, 5, 1, 6, 7, 4, 9, 9, 2, 3, 6 Frequency: the number of times an item occurs in data

4. FREQUENCY DISTRIBUTION TABLE Frequency distribution table: a table used in statistics as a method of recording the data collected Vehiclefrequency Car llll (4) Truck lll (3) motorcycle llll (5)

5. LINE PLOT Line plot: a number line long enough to encompass all numbers in the sample, showing a dot or mark over the position corresponding to each number often - used with frequency tables

6. GRAPH Graph: drawing or diagram used to record information

7. INTERVAL Interval: the distance between the numbers on a scale or graph interval = 10 50 - 40 - 30 - 20 - 10 - 0

8. LINE GRAPH Line graph: graph that shows how data changes over time

9. AVERAGE or MEAN Average: number found by dividing the sum of a set of numbers by the number of addends; average and mean are synonyms 100, 85, 100,90,95 Step 1: add 100 + 85 + 100 + 90 + 95 = 470 Step 2: divide: 470 5 = 94%

10. MEDIAN Median: the middle value in an ordered set of values 100, 85, 100,90,95 Step 1: ORDER THE NUMBERS 100, 100,, 90, 85 Step 2: CROSS OFF VALUES UNTIL YOU FIND THE MIDDLE VALUE

11. RANGE Range: the difference between the highest and lowest number in a given set of numbers 100, 100, 95, 90, 85 100 – 85 = 15

12. MODE MO de: the number that occurs m ost o ften in a given set of numbers 100, 85, 100, 90, 95

13. PICTOGRAPH Pictograph: Graph which uses pictures to represent quantities

14. PIE CHART Pie Chart: a graph using a divided circle where each section represents part of the total

15. SCALE Scale: the series of numbers placed at fixed distances on a graph scale 50 - 40 - 30 - 20 - 10 - 0

16. STEM AND LEAF PLOT Stem and Leaf Plot: a data display that shows groups of data arranged by place value

17. TABLE Table: mathematical information organized in columns and rows Favorite Zoo Animal Woodpecker 6 Koala 10 Giraffe 9 Elephant 8 Cobra 4

18. TALLY Tally: marks used to record counting

19. TREE DIAGRAM Tree diagram: a diagram shaped like a tree to display sample space by using one branch for each possible outcome

20. VENN DIAGRAM Venn Diagram: diagram that uses geometric shapes to show relationships between sets
