============
tab name if HoursPWeek > 90
will give you all observations which are greater than 90, which includes all missing values. Tab "help missing".
You may want to do:
tab name if HoursPWeek > 90 & HoursPWeek<.

> I have 10032 observations.
> Like 200 of them have announced to be working more than 90 Hours per Week.
> (There are also 3000 missing values). I can see that doing "tab HoursPWeek".
>
> The strange thing, is that if I call another variable, for example:
> "tab name if HoursPWeek > 90", then the answer is about 3000 observations.
> How can that be?
>
> Another strange thing:
> If I say "tab name" if HoursPWeek==99.9 there are "no observations"
> although I can clearly see in the data, there are some.
