Question

1- When we perform ______________, an element of a population always has a chance of being chosen at each point of selection.

Stratified random sampling

Sampling with replacement

Sampling without replacement

Cluster sampling

2-__________ sampling is defined as sampling where we know the chance that each element in the population will be included in the sample.

Judgment

Convenience

Nonrandom

Probability

Answer 1

1) In Sampling with replacement each element of population always has equal chance of selection at each point of selection.

Hence Sampling with replacement is the correct answer.

2) A probability sampling sceme is the one in which every unit in the population has a chance of being selected in the sample and this probability can be accurately determined.

Hence  Probability   sampling is defined as sampling where we know the chance that each element in the population will be included in the sample.
