About the Transformed Data in a Basketball Game Analysis

"... How and why can we transform data from a basketball game analysis ..."

As we studied at the eBA Basketball Statistics Clinic ONLINE, sometimes, we transform data from a basketball game analysis, for example, to make fit the number of turnovers from one team to the steal of the other in relation to the total of possessions adding it to the statistics of the "team player".

I've never been a "fan" of transforming data, because you need a reason for log transformation. There are many types of transformations too.
but now, if you decide to do a transformation, then you should do the hypothesis test using transformed data.

The reason I don't like transforming data, is because interpreting the results is always problematic: telling a head coach about the log of the data points will always get you a puzzled look, and this is not good.

If the data are skewed badly enough, then you may want to consider:
a.- finding probable causes for the "outliers" and removing them, or
b.- using a nonparametric method.

However, if there's a really, really good reason, then there are virtually unlimited ways to transform data, as we studied at the eBA Basketball Statistics Clinic - just make sure you pick the one that meets your analytical needs....

See in our forum the transformed data topics and the exposition "Basketball Statistics and Statisticians" at eBA ONLINE.

All the terms in this answer are explained widely at The Global Basketball Encyclopedia and in eBA ONLINE.
