Explanation:

For statistics to be representative, a proper - proportioned sample of different population groups is crucial as it reflects the overall population structure. Also, a large - enough sample size reduces sampling error and increases the likelihood of accurately representing the population. Manipulating statistics is unethical and having equal numbers of adults, senior citizens, and children is not always necessary as long as proportions in the population are reflected.

Answer:

• Different groups of a population sample must be in correct proportion.
• The sample size must be large enough.
