This question aims to assess your relevant experience and how it aligns with the organization's mission.

How to Answer

Discuss specific projects or roles where you analyzed public health data, emphasizing your contributions and the impact of your work.

Example

“In my previous role at a public health agency, I analyzed data from the Behavioral Risk Factor Surveillance System to identify trends in chronic diseases. My analysis helped inform local health initiatives, leading to a 15% increase in community engagement in health programs.”

2. Describe a time when you had to clean and manage a large dataset. What challenges did you face?

This question evaluates your data management skills and problem-solving abilities.

Statistical Analysis

3. Can you explain the difference between descriptive and inferential statistics?

This question tests your foundational knowledge of statistics.

How to Answer

Provide clear definitions and examples of both types of statistics.

Example

“Descriptive statistics summarize data from a sample using measures like mean and standard deviation, while inferential statistics use a random sample to make inferences about a population. For instance, I used descriptive statistics to summarize survey results, and inferential statistics to predict health trends based on that data.”

4. How do you approach hypothesis testing?

This question assesses your understanding of statistical methods.

How to Answer

Outline the steps you take in hypothesis testing, including formulating hypotheses, selecting a significance level, and interpreting results.

Example

“I start by formulating a null and alternative hypothesis based on the research question. I then choose an appropriate test, such as a t-test, and set a significance level, typically 0.05. After conducting the test, I interpret the p-value to determine whether to reject the null hypothesis, ensuring I contextualize the results within the study's framework.”

Software Proficiency

5. What statistical software are you proficient in, and how have you used it in your previous roles?

This question gauges your technical skills and familiarity with relevant tools.

How to Answer

Mention specific software and provide examples of how you utilized them in your work.

6. Describe your experience with SQL. Can you provide an example of a query you wrote?

This question assesses your database management skills.

How to Answer

Discuss your experience with SQL and provide a specific example of a query you wrote, explaining its purpose.

Example

“I have used SQL extensively to extract and manipulate data from relational databases. For instance, I wrote a query to join multiple tables to analyze patient demographics and health outcomes, which allowed us to identify at-risk populations for targeted interventions.”

Communication Skills

7. How would you explain a complex data analysis to a non-technical audience?

This question evaluates your ability to communicate effectively.

How to Answer

Discuss your approach to simplifying complex concepts and ensuring understanding.

Example

“I focus on using clear visuals and relatable analogies. For example, when presenting data trends, I use graphs to illustrate changes over time and explain the implications in straightforward terms, ensuring the audience understands the significance without getting lost in technical jargon.”

8. How do you handle criticism of your data analysis?

This question assesses your ability to receive feedback and improve.

How to Answer

Explain your approach to constructive criticism and how you use it to enhance your work.

Example

“I view criticism as an opportunity for growth. When I receive feedback, I take time to reflect on it and assess how I can improve my analysis. For instance, after a presentation, I received feedback on my data visualization techniques, which prompted me to take a course on effective data storytelling, significantly enhancing my future presentations.”
