Who's Normal?
The information Age

I thought this would get your attention. We often like to consider ourselves normal, but some like to be different.

In terms of statistics normality is usually associated with our averages, specifically mean, median and mode. In an age where data is key to decision making, finding out the norm is a powerful tool in business.

What about the extremes then, is there value in knowing that? Of course, when we build things in construction or engineering, we need to know what our inventions have to withstand.


We need to collect and categorise data. This can be done using surveys or projects. There are methods for taking samples, for example using tables. We need to plan carefully, thinking ahead of what we really need to look at.
