Unit 4: Inferences about Populations Box Plots Measures of Variability Data Distribution Median Inferences Population Interquartile Range Random Sample Lower Quartile Representative Sample Mean Statistics Mean Absolute Deviation Upper Quartile Quartiles Variation/Variability Measures of Center

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

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

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?

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

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

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:

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:

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%, 76-100% of the data. Model:

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

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

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

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

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

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

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

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

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

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).

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.

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

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.
