What is an advantage of a standardized statistic (e.g. t-statistic) over a statistic that is not standardized (e.g. difference in means)? 

A. It is easier to estimate strength of evidence from a standardized statistic than it is from one that is not standardized. 

B. Standardized statistics allow us to determine p-values, whereas those that are not standardized do not. 

C. Standardized statistics are much easier to calculate than those that are not standardized. 

D. Standardized statistics will always give smaller p-values than those that are not standardized, thus allowing for stronger evidence against the null.
