Another way is to put a pencil on the trend line. If the data points are plotted on the trend line, then the data is normal. There are 2 ways of checking data normality – Visual Check & P-valueĭata is plotted on Normality Plot in Minitab with data points being displayed on the trend line. However, it is not a difficult task and Minitab provides all the tools you need to do this. In practice, checking for assumptions 2, 3 and 4 will probably take up most of your time when carrying out a Pearsons correlation.

Key statistical tests include t tests, one and two proportions, normality test, chi-square, and equivalence tests.
#Minitab normality test software
There are multiple ways of checking normality of data, with the most commonly used being Anderson Darling test. This can be done using the Shapiro-Wilk test for normality, which you can carry out using Minitab. Only Minitab offers a unique, integrated approach by providing software and services that drive business excellence from anywhere with the cloud. Parametric tests are Mean based tests where Mean is used while Non-Parametric tests are Median based tests using median.
#Minitab normality test how to
Based on this result, it is decided which type of tests are to be performed on the data – Parametric or Non-Parametric, hence How to check data normality in Minitab is very important. Normality Check is one of the most important tests performed to check whether data is normal or not normal. How to check data normality in Minitab is an important knowledge to acquire for practitioners.
