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.

Mutually Exclusive In logic and probability theory, two propositions (or events) are mutually exclusive or disjoint if they cannot both be true (occur). A clear example is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.

Mode The mode of a set of data values is the value that appears most often. It is the value x at which its probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled. {6, 3, 9, 6, 6, 5, 9, 3}

outlier an observation that lies an abnormal distance from other values in a random sample from a population.

Measures of Spread describe how similar or varied the set of observed values are for a particular variable (data item). Measures of spread include the range, quartiles and the interquartile range, variance and standard deviation.

Grouped Frequency Table is a statistic method to organize and simplify a large set of data in to smaller "groups." When a data consists of hundreds of values, it is preferable to group them in a smaller chunks to make it more understandable.
