Hello
This is presumably why we have invented standard scores expressed as
whole integers, such as IQ, SAT, T-score and GRE rather than use the
original Z score. It is much easier to conceptualize an IQ score of 117
rather than an IQ of 1.13. I once designed a clipboard with an imprint
that included a conversion table. Since Z is never used, it only
included IQ, T and %tiles:

You might find it handy as a tool illustrating the relationship of
statistics to clinical testing practice.

I hate to say this, but thank you.
I have often wondered why so many students would be baffled by the decision
process. [if p<.05, reject the null hypothesis]. It seems so easy… but, if you
are not comfortable with the numbers between 0.00 and 1.00, then it is a real
problem.
