Question

This technique provides an equal chance for everyone in the universe to be selected for the poll

Answer 1

random sampling - the selection of a random sample; each element of the population has an equal chance of been selected

Answer 2

In random sampling, three methods are most common when conducting surveys. Random number tables, more recently known as random number generators, tell researchers to select subjects at an interval generated randomly. Mathematical algorithms for pseudo-random number generators may also be used. Another method used is physical randomization devices.
