sampling
what is a census - correct answers ✔✔data collected from
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
the entire population
||\\||\\ ||\\||\\ ||\\||\\
define population - correct answers ✔✔the whole set of ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
items that are of interest ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
define sample - correct answers ✔✔some subset of the ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
population intended to represent the entire population ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
, whats a sampling unit - correct answers ✔✔each
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
individual to be measured ||\\||\\ ||\\||\\ ||\\||\\
whats a sampling frame - correct answers ✔✔a list of
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
thing to be sampled from
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
what is simple random sampling - correct answers ✔✔-
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
assign each item a number ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
-use a RANDOM NUMBER GENERATOR to pick numbers
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
-sample from the items that are assigned the picked ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
numbers
what are the advantages of simple random sampling -
||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\ ||\\||\\
correct answers ✔✔-bias free ||\\||\\ ||\\||\\ ||\\||\\
-cheap and easy ||\\||\\ ||\\||\\
-each item has an equal chance of being selected
