The bell curve, perhaps one of the most discussed concepts in statistics, may need to be redefined. Or shall I say reformed? Perhaps for the first time in human history, an external force, we call technology, may change the shape of the normal curve. How so you may be asking.
This is how. These are the characteristics of the bell curve.
- The mean is always at the center
- It has only one peak
- It’s by definition unimodal
- It may be bimodal in some instances
- But normality is expected
68% of the population falls in the mean. 68% of the population is then normal.
Technology reforms the bell curve by giving people choices. By being able to choose, outliers are then able to gather their own groupies and start their own bell curves. As choices increase, smaller bell curves are then created reducing the normal, increasing the edges and reshaping the curve into a series of other sub curves perhaps forever.
How is the new bell cure going to look like?
This is how, I think. These may be the characteristics of the new bell curve.
- The mean is perhaps to be located at the edges in the long tail
- Multiple peaks may be the new norm
- Unlikely unimodal form
- Bimodal form expected if not multimodal
- Normality is under attack
As the rate of technology innovation increases, normality decreases. If normality then decreases, the new norm falls in the long tail. Outliers are then the new normal. If the former is true, then the concept of the bell cure must be redefined. Technology advances is then the fuel of these reform.
Oh my… It’s 2019. What is next?
