Provide a brief description of a real-world example in which one measure of central tendency provides useful information while another measure of central tendency provides meaningless (or even misleading) information.
There are three most common forms of measure of central tendency and they are:
mean, median and mode.
The mean is an average rating. It takes the average of a group of numbers to summarize it into one figure.
The median is the number right in the middle of a set of numbers.
The mode is the most common number in the set.
The first example I will give can be a useful measure.
Lets say that you want to examine the weight of new born babies. The mode is useless, since knowing the most common value gives very little valuable insight. A good measure would be to use the median. This is the number that is ...
This posting looks at three measures of central tendency: mean, median and mode, explains each term, and gives real life examples of how they are used. It also explains how the data can be misleading in some situations.
