MEAN The average of the data set. Population: Sample:

MEDIAN The middle number after they are put in order

MODE The number that occurs most often. Mode:7

BIMODAL When the data set has more than one mode

INNER QUARTILE RANGE The range between Q1 and Q3

OUTLIER A data entry that is far removed from the other entries in the data set.

WEIGHTED MEAN The mean of a data set whose entries have varying weights. SOURCESCORE, xWEIGHT, wxw Test Mean Midterm Final Computer Lab Homework

MEAN OF FREQUENCY DISTRIBUTION Finding the mean of grouped data. Where x and f are the midpoints and frequency of a class

SYMMETRIC DISTRIBUTION When a vertical line can be drawn through the middle of the graph and the resulting halves are approx. mirror images

UNIFORM DISTRIBUTION When all entries or classes have equal frequencies

SKEWED RIGHT A distribution where the tail extends to the right. (Positively Skewed)

SKEWED LEFT A distribution where the tail extends to the left. (Negatively Skewed)
