4. UNit 5
Box Plots
Definition: A representation that makes use of the quartiles, median, minimum and maximum in reporting data.
Model:

5. UNit 5 Data Distribution
Definition: A measure or description of spread or range of data.
Model:

6. UNit 5
Inferences
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?

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

8. UNit 5
Lower Quartile
Definition: The point where 25% of the data is below and 75% of the data is above.
Model:

9. UNit 5
Mean
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:

10. UNit 5 Mean Absolute Deviation
Definition: A way to describe the variability of data. The average distance every element is from the mean of the data.
Model:

11. UNit 5
Quartiles
Definition: The mark on a set of data that divides it into 4 parts or quarters. 0-25%, 26-50%, 51-75%, % of the data.
Model:

12. UNit 5
Meaures of Center
Definition: Values that describe the middle of a set of data. Mean, Median, and mode are most common.
Model:

13. Measures of Variability
UNit 5
Measures of Variability
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

14. UNit 5
Median
Definition: 2nd Quartile, 50th percentile or arithmetic mean of middle two values in an ordered set.
Model:

15. UNit 5
Population
Definition: The entire group from which data could be gathered.
Model:

16. UNit 5
Random Sample
Definition: A sample in which every element in the set has an equal chance of being selected.
Model:

17. Representative Sample
UNit 5
Representative Sample
Definition: A subset of a statistical population that accurately reflects the members of the entire population.
Model: Whole Population organized population representative sample

18. UNit 5
Statistics
Definition: The gathering, organizing and interpreting of data.
Model:

19. UNit 5
Upper Quartile
Definition: The median of the upper half of the data. It delineates the 75% mark within the data.
Model:

20. Variation/Variability
UNit 5
Variation/Variability
Definition: How much something (like a set of data) changes from element to element.
Model:

21. Stem and Leaf Plots
Definition: A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).

22. Histogram
Definition: a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.

23. Frequency
Definition: The frequency of a particular data value is the number of times the data value occurs. For example, if four students have a score of 80 in mathematics, and then the score of 80 is said to have a frequency of 4

24. Mean
Definition: The mean is the average of the numbers: a calculated "central" value of a set of numbers.
To calculate: Just add up all the numbers, then divide by how many numbers there are.
