In chemistry, memorizing formulas for different acids will make it easier to make sense of information about those acids. And in physics, memorizing Bernoulli’s or Poisson’s equations supports your understanding of the relationships those equations represent.

A variable is assumed to be normally distributed where: 68% of all values should fall within one standard deviation of the average, 95% of all values should fall within two standard deviations of the average, 99.7% of all values should fall within three standard deviations of the average and 99.9% of all values should fall within four standard devi

the mathematical secret behind finding curves of minimum length, or any other property.

Explanations bind facts together. They make them all the more easily remembered; they help them make more sense. Where this propensity can go wrong is when it increases our impression of understanding.

The core principle underlying the central limit theorem is that a large, properly drawn sample will resemble the population from which it is drawn.

To compute a 95% confidence interval, you need three pieces of data: The mean (for continuous data) or proportion (for binary data) The standard deviation, which describes how dispersed the data is around the average The sample size

standard deviation provides an estimate of the average difference of each value from the mean.
