normalization of distribution of an interval variable with non normal distribution

[layeghpa]

hi , when an interval variable has not normal distribution , can we always be able to use the compute command in spss for transforming this variable by LG10 or SQRT for normalization of distribution ? thanks for your help

You can probably always use them, but it may not make them normal. Using these transformations on very skewed data does not always make them normal.

They also require the data to be non-negative (for sqrt) or positive (for log)
