How Do You Check For Nearly Normal Conditions? If you have raw data, graph a histogram to check to see if it is approximately symmetric and sketch the histogram on your paper. If you do not have raw data, check to see if the problem states that the distribution is approximately Normal. How do you
How Do You Test For Normality? The two well-known tests of normality, namely, the Kolmogorov–Smirnov test and the Shapiro–Wilk test are most widely used methods to test the normality of the data. Normality tests can be conducted in the statistical software “SPSS” (analyze → descriptive statistics → explore → plots → normality plots with tests).
How Do You Test If Data Is Normally Distributed? The most common graphical tool for assessing normality is the Q-Q plot. In these plots, the observed data is plotted against the expected quantiles of a normal distribution. It takes practice to read these plots. In theory, sampled data from a normal distribution would fall along
