The simple random sampling describes a simple sampling technique where a portion of the population can be selected while giving every member of the population an equal chance of being selected. Hence, the true statements from the option are :
- sample of size n from the population has an equal chance of being selected.
- Every member of the population has an equal chance of being included in the sample
The simplest method of selection is used to create a representative sample
The simple random sampling techniques is easy, starignforward and effective, it is arguably the simplest method of selecting a truly representative sample.
Every single member of the population is given an equal chance of being selected in this sampling procedure, which also means that a sample of size also has an equal chance of being selected.
Therefore, only statements
- sample of size n from the population has an equal chance of being selected
- Every member of the population has an equal chance of being included in the sample
- The simplest method of selection is used to create a representative sample
are true of simple random sampling technique.
