Lesson 11 - PS 3a: Central Tendency (Engl. Terminology)

uniform distribution

A ... ... has no mode and a constant probability. (See lesson 11 PS 3a, 5., 5. quiz)

sample size

A ... is a part of the population chosen for a survey or experiment. (Source: Statistics How To) (See lesson 11 PS 3a, 1., 1. quiz)

even

Approach to find the median: 1. Order the data set from least to greatest. 2. If there is an ... number of items, the median is found by taking the average of the two central numbers. (See lesson 10, 29. quiz; lesson 11 PS 3a, 13., 22. quiz)

odd

Approach to find the median: 1. Order the data set from least to greatest. 2. If there is an ... number of items, the median is the middle number. (See lesson 10, 29. quiz; lesson 11 PS 3a, 13., 22. quiz)

normal

In a ... distribution, the mean, median and mode are approximately equal. It has a single peak and is symmetric. (See lesson 11 PS 3a, 6., 6. quiz)

mode

Which measure of center is described below? - It's not affected by extreme scores (outliers). - It's the most frequently occurring score. - It can be used to describe categorical data, such as gender or country of origin. - It has no equation. (See lesson 10, 30. quiz; lesson 11 PS 3a, 10., 10. quiz)

median

Which measure of center is described below? - It's the exact middle of any distribution (half the data is less than the ..., half is more). - It's not affected by extreme scores (outliers). - It's not affected by change in bin size. (See lesson 10, 30. quiz; lesson 11 PS 3a, 9., 9. quiz)
