    sampling:
    A Every individual in the population has an equal chance of selection. Correct Answer Incorrect Answer
    B The population is divided into homogeneous groups, and a random sample is taken from each. Correct Answer Incorrect Answer
    C The population is divided into heterogeneous groups (clusters), and a random sample of clusters is chosen, surveying all within them. Correct Answer Incorrect Answer
    D Samples are selected at regular intervals from a list. Correct Answer Incorrect Answer
    E The researcher uses their judgment to select representative units. Correct Answer Incorrect Answer

    Solution

    Cluster sampling divides the population into heterogeneous clusters (e.g., city blocks, schools) that each mirror the population. A random sample of clusters is selected, and then all units within the chosen clusters are surveyed. It's cost-effective for geographically dispersed populations.
