1. Question: What is the purpose of using biostatistical

methods in public health research?

Answer: Biostatistical methods enable researchers to

analyze and interpret data to draw meaningful conclusions

about public health issues. By using these methods, public

health professionals are able to make evidence-based

decisions and implement effective interventions.

2. Question: Explain the concept of statistical significance

and its significance in public health research.

Answer: Statistical significance refers to the probability

that observed differences or relationships in data are not

due to chance. In public health research, statistical

significance helps determine the validity of study findings

and provides evidence to support or reject hypotheses.

3. Question: How do confidence intervals contribute to the

interpretation of study results in public health research?

Answer: Confidence intervals provide a range of values

within which the true population parameter is likely to fall.
