  1. When conducting a focus group for health program evaluation, the ideal group size is typically:

    Answer: 6–10 participants

    Groups of 6–10 participants allow enough diversity of opinion while still enabling meaningful group discussion.

  2. A CHES professional observes a significant difference in test scores (p = 0.03). What does this p-value indicate?

    Answer: There is a 3% probability of obtaining these results if the null hypothesis is true

    A p-value of 0.03 means there is a 3% probability that the observed difference occurred by chance if the null hypothesis were true.

  3. Which ethical principle requires that research participants understand the nature of the study before agreeing to participate?

    Answer: Informed consent

    Informed consent ensures participants are fully informed about study procedures, risks, and their right to withdraw before agreeing to participate.

  4. Construct validity refers to the extent to which an instrument:

    Answer: Accurately measures the theoretical concept it is designed to measure

    Construct validity assesses whether a measurement tool truly captures the underlying theoretical construct it represents.

  5. In the CDC evaluation framework, 'stakeholder engagement' is emphasized because:

    Answer: It ensures that evaluation findings are used and meet the needs of those involved

    Engaging stakeholders ensures the evaluation is relevant, credible, and that findings will be acted upon by those with a stake in the program.

  6. Which sampling method ensures every member of the population has an equal chance of selection?

    Answer: Simple random sampling

    Simple random sampling gives each population member an equal and independent chance of being selected, supporting generalizability.

  7. A health educator uses a pre-validated instrument from a prior study. This practice primarily supports:

    Answer: Measurement reliability and comparability across studies

    Using validated instruments improves reliability and allows meaningful comparison of results with other studies using the same tool.
