Uhh, no. In the example you provided, the samples are selected based on school.
WHat is the sampling unit in my example (it seems we will have to go VERY basic for you) quote:
pparently it means grouping samples of students based on school - rather than based on random selection.
Look up the concept of nesting as it relates to randomization and get back to me champ. BTW, these are intro level stats questions. The fact you have such difficulty with them is astoundign for a PhD in astrophysics.

A school's worth of students. Which you select not at random - but based on which school a student attends.

Continuing to show off your superficial understanding of statistics isn't going to help you with your fundamental misunderstandings - or, as I feel the case probably is - your inability to admit you were wrong.

You don't even understand what constitutes a random sample.
