What is The Best Way to Calculate Variance?


The average of the squared differences from the Mean.

To calculate the Variance, take each difference, square it, and then average the result:

variance calc

So the Variance is 21,704

And the Standard Deviation is just the square root of Variance, so:

Standard Deviation
σ = √21,704
= 147.32…
147 (to the nearest mm)

So, using the Standard Deviation we have a “standard” way of knowing what is normal, and what is extra large or extra small.

Rottweilers are tall dogs. And Dachshunds are a bit short … but don’t tell them!

But … there is a small change with Sample Data

Our example has been for a Population (the 5 dogs are the only dogs we are interested in).

But if the data is a Sample (a selection taken from a bigger Population), then the calculation changes!

At present, more than half of the worldwide populace lives in urban regions. With more individuals living in thick conditions, there is more regular contact between more people, enabling malady transmission to effectively happen.

Relocation and worldwide travel – As it turns out to be more typical for individuals to go all through the world, it additionally ends up plainly less demanding for illnesses to go with them.
