I am interested to know either the data is parametric of non-parametric. Anyway you can use QQ plot to check. Linear regression can also be used as an option.You can use nonparametric alternatives to analyze the data. No need to stuck for normality. Good Luck

What does your data look like? Do you need normally distributed data? If so you can check whether you have outliers that you can remove so your data will become normally distributed.

Yaser Hasan

it would be helpful if you could provide more details about your data.
