Would you agree to the statement on random sampling methods. Please explain why. In probability samples “each population element has a known (non-zero) chance of being chosen for the sample.” (StatTrek 2020). Some examples of probability samples are, simple random sampling, stratified sampling, cluster sampling, multistage sampling, and systematic random sampling. Simple random sampling is the population and sample consists of “N” objects, and an example is when people play the lottery. Stratified sampling is based on some type of...

Measuring all individuals within randomly selected groups from the population. C. Assigning a different number to each member of the population. D. Randomly selecting an integer between 1 and k and sampling at k intervals.

Probability Sampling techniques represent the most rigorous category of sampling because they employ a random selection technique, which ensures that each element has an equal probability of being selected. Which of the following are examples of probability sampling techniques (check all that apply)?
