What’s the average number of feet?
No, not two.
The answer is slightly less. Think about it.
The BBC News Magazine is running a really nice series on maths.
If the thought that nearly everyone can be below average makes no sense, you might be muddled by the middle.
“Average” is commonly used to mean something like “ordinary”, “typical”, “normal” or “what’s expected”. Above is good, below is bad.
Organisations can apply a range of techniques to analyse data effectively for business purposes. By using the mean, median and mode, businesses can analyse their sales and costs to make effective business decisions.
For example by knowing both the average (mean), median and mode of sales by outlet or division, they can compare effectively which areas of the business need action.
Relying on one average (such as the mean) can result in ineffective decisions as sometimes averages can be swayed by a few high figures as explained in the BBC article.
