Central tendency

In statistics, a central tendency (or measure of central tendency) is a central or typical value for a probability distribution. Colloquially, measures of central tendency are often called averages. The term central tendency dates from the late 1920s. The most common measures of central tendency are the arithmetic mean, the median, and the mode. A middle tendency can be calculated for either a finite set of values or for a theoretical distribution, such as the normal distribution. Occasionally authors use central tendency to denote "the tendency of quantitative data to cluster around some central value." The central tendency of a distribution is typically contrasted with its dispersion or variability; dispersion and central tendency are the often characterized properties of distributions. Analysis may judge whether data has a strong or a weak central tendency based on its dispersion. (Wikipedia).

What is Central Tendency – An Introduction to Mean, Median, and Mode in Statistics (5-1)

When we seek to organize our jumbled data, our first question is “what single number best represents our data?” The answer is a measure of central tendency: where does the CENTER of our data TEND to be? There are three measures that we will dig into: mean, median, and mode. Later, we will

Explaining CENTRAL Tendency and Variability for Statistics (5-2)

The first two questions that we will have about any distribution is (1) where is the center of the distribution and (2) how close together or spread out are the scores? We answer the first question with central tendency. Central tendency is a single number that represents all of the other

Measures of Location, Mean, Median, Mode and Central Tendency in Business Statistics (Week 5A)

Three measures of central tendency (i.e. location) tell us mean, median, and mode of data. We choose our measure of location based on the level of the data, such as the mode for nominal, median for ordinal, and mean for scale variables. We may change our measure of location based on the ch
