▶︎ In this statistics video tutorial we will learn the normal distribution definition, and the concept of standardizing and Z-score and using z table. Here we will also learn about the empirical rule or the (very handy) 68,95,99.7 rule or 1,2,3 standard deviation rule.
▶︎ The normal distribution is a very important probability distribution used in statistics, and it is important that you build a solid understanding of the concept and its properties. Standardizing and creating a z-score is simply a unit-conversion.
▶︎ We will work through some of the calculations for normal distribution and z scores, although we will focus on the concept of normal distribution and z-scores, not the calculations, as the calculations as simply mechanical, and can usually be done using software.
