I was wondering if anyone could answer what is probably quite an obvious question...

I've got a dataset with 9 variables, of which I am looking to combine 8 paris... (after standardization) so that I end-up with a dataset of 5 variables.

One of the variables (which I intend to combine) is positively skewed. I'm planning to do a Log transformation to sort this out... but is it then okay to sandardize the new Log score in to a Z score (ie. to standardize it)???

I've looked in a few books (Howell, Field), but none seem to talk about transformation followed by standardization...

I'd be really grateful for any help.
