This is why abstract ideas such as mathematical formulas are used to help bridge this gap and create a model that can actually be grasped by the human mind and eventually blended with reason to create a useful and practical tool that can help develop even better predictive models that can assist a society or environment in better ways.
The standard deviation formula contains Greek letters and high order mathematical symbols to help create a cohesive model that can be manipulated by calculation. The goal of the formula is to solve for ? (sigma) which aims to demonstrate how far a piece of data strays from the mean or average of a collected larger group of data. The higher the sigma value…
