1. 7 th Grade Math Vocabulary Word, Definition, Model Emery Unit 4

2. UNIT 4 Definition: A representation that makes use of the quartiles, median, minimum and maximum in reporting data. Model: Box Plots

3. UNIT 4 Definition: A measure or description of spread or range of data. Model: Data Distribution

4. UNIT 4 Definition: When you take new knowledge and combine with existing knowledge to come to a conclusion. Model: If one student is sick and is in ISS with 10 other students, How many students will most likely be sick the next day? Inferences

5. UNIT 4 Definition: The range between the upper quartile (75% mark) and the lower quartile (25% mark) Model: Interquartile Range

6. UNIT 4 Definition: The point where 25% of the data is below and 75% of the data is above. Model: Lower Quartile

7. UNIT 4 Definition: The mean is the arithmetic average. It is determined by dividing the sum of the values in a set of data by the number of values in the set. Model: Mean

8. UNIT 4 Definition: A way to describe the variability of data. The average distance every element is from the mean of the data. Model: Mean Absolute Deviation

9. UNIT 4 Definition: The mark on a set of data that divides it into 4 parts or quarters. 0-25%, 26- 50%, 51-75%, 76-100% of the data. Model: Quartiles

10. UNIT 4 Definition: Values that describe the middle of a set of data. Mean, Median, and mode are most common. Model: Meaures of Center

11. UNIT 4 Definition: Measures that describe the amount and degree of change within a set of data. Model: Three measures of variability: range, variance and standard deviation Measures of Variability

12. UNIT 4 Definition: 2nd Quartile, 50th percentile or arithmetic mean of middle two values in an ordered set. Model: Median

13. UNIT 4 Definition: The entire group from which data could be gathered. Model: Population

14. UNIT 4 Definition: A sample in which every element in the set has an equal chance of being selected. Model: Random Sample

15. UNIT 4 Definition: A subset of a statistical population that accurately reflects the members of the entire population. Model: Whole Population organized population representative sample Representative Sample

16. UNIT 4 Definition: The gathering, organizing and interpreting of data. Model: Statistics

17. UNIT 4 Definition: The median of the upper half of the data. It delineates the 75% mark within the data. Model: Upper Quartile

18. UNIT 4 Definition: How much something (like a set of data) changes from element to element. Model: Variation/Variability
