Learn how to apply the normal distribution to solve problems with step-by-step examples and detailed solutions.

Normal distribution follows the central limit theory which states that various independent factors influence a particular trait. When these all independent factors contribute to a phenomenon, …

To test your data analytically for normal distribution, there are several test procedures, the best known being the Kolmogorov-Smirnov test, the Shapiro-Wilk test, and the Anderson Darling …

The amount of time a student taking statistics spends on studying for a test is normally distributed. If the average time spent studying is 12 hours and the standard deviation is 4 hours, what is …

Most likely you’re fitting some type of statistical model to your data such as ANOVA, linear regression, and nonlinear regression. In these cases, the assumption is that the residuals, the …

Many statistical tests rely on the assumption that data is distributed according to a normal or Gaussian curve, and if the data is not normal these tools won't work. Statisticians can use both …

Now let's look at three concrete examples to see how we can use the properties of the normal distribution to answer questions about our datasets. We'll start with simple questions and work …
