Distinguish between random sampling and systematic sampling with example . Pls Fastt

Random sampling: If you choose all of your samples randomly, like sampling every 3rd person to walk into a room.

Systematic sampling: If you only sample certain people, like only blonds, or only guys. Stuff like that.

The difference between these types of samples has to do with the other part of the definition of a simple random sample. To be a simple random sample of size n, every group of size n must be equally likely of being formed. A systematic random sample relies on some sort of ordering to choose sample members.
