Hello,
I am carrying out two-ways ANOVA analysis on different random variables and I need your comments please to make sure that I am (being not statistician or probability guy) not doing an error
1- Should these random variables be normally distributed in order for ANOVA analysis and the following regression analysis applied on these variables to be valid
2- I have a random variable (water depth below the ground) with Mean value of 1 m and Minimum value of 0 and maximum value of 2.5 m . Since I don't have sufficient data on the variability of this variable(other than the minimum and max values) I am trying to represent this variable ( with above mean and min and max values ) by a normally distributed function. Is that assumption valid,,?
If yes how can I calculate the standard deviation of this variable
Thanks
