Web13 de dez. de 2024 · The QQ Plot allows us to see deviation of a normal distribution much better than in a Histogram or Box Plot. 3.2. Interpretation. If our variable follows a normal distribution, the quantiles of our variable must be perfectly in line with the “theoretical” normal quantiles: a straight line on the QQ Plot tells us we have a normal distribution. WebNormality test. One of the most common assumptions for statistical test procedures is that the data used must be normally distributed. For example, if a t-test or an ANOVA is to be calculated, it must first be tested whether the data or variables are normally distributed. If the normal distribution of the data is not given, the above procedures cannot be used and …
