Please Doctor Omar, when the values do not follow the normal distribution, we writte them with mean and standard deviation or with median and quartile
Dear Mehri First try to transform you data to become normally disctributed, if this is not successful then your data are nonparamteric and you will use non parametric test. Again, this depend on the type of data categorial or continous. If you will stick to nonparametric data then use Box Plot is the one. Have a look at the videos on my channel. ruclips.net/video/pHevXpMMTMo/видео.html ruclips.net/video/cBAxAqdYuxs/видео.html There are many videos for data transformation.
@@StatisticsTutor Dear Dr Omar , I saw your excellent video, and I applied it to my data, the result of all the transformations are not normally distributed. can you please give me your email
