...Introduction to Statistics (Measures of CentralTendency)
CentralTendency: In a representative sample, the value of a series of data have a tendency to cluster around a certain point usually at the center of the series is usually called centraltendency and its numerical measures are called the measures of centraltendency or measures of location.
Different...
...Week Five Discussion

This Discussion will give you the opportunity to calculate or identify the three measures of centraltendency. You will be asked to select an appropriate real life situation in which one measure would be more appropriate than the other two measures of center.
1. Select a topic of interest to you and record the topic in your posting, for example: “What is the average number of hours people watch TV every week?” Make sure the question...

...1 Measures of CentralTendency
“Measures of centraltendency (averages) are statistical constants which enable us to figure out in a single effort the significance of the whole.” (Prof Bowley)
The main objectives of measure of centraltendency are
To reduce data in a single value.
To make easy comparisons between data.
There are different types of averages; each has its own business applications.

CentralTendency
Measures of CentralTendency
There are many ways of describing of a
given set of data. A good number of descriptive
measures exist in statistics whose use depends
largely on the nature of data and the intended
purpose of the description. This measure is the
measures of position or centraltendency, it is
use to see how a large set of raw materials can
be summarized so that the...
