What is a representative sample?
A representative sample is a small number, part, or subset of a larger set or entity of cambodia phone number people, and has the same properties as the larger population of which it is representative.

For example, a class of 30 students with 15 males and 15 females might generate a representative sample that included six students: three males and three females.

Samples are useful in statistical analysis when the population size is large because they contain smaller, more manageable versions of the larger group.

A representative sample reflects, as accurately as possible, a larger group. So we can apply, for example, an online survey to a sample seeking to make it as representative as possible of our target population.

We will not have better results if, for example, we send a survey without taking into account representativeness and we do not know who answers it, and if the results really represent the opinion of our audience.
