Interview Questions and Answers

Ethical considerations include ensuring data privacy and confidentiality, avoiding conflicts of interest, and accurately reporting results.

Biostatisticians contribute to public health by designing and analyzing studies to understand disease patterns, evaluate interventions, and inform public health policies.

Career opportunities include positions in academia, government agencies (e.g., NIH, CDC), pharmaceutical companies, research institutes, and healthcare organizations.

Confounding occurs when a variable is associated with both the exposure and the outcome, leading to a distorted estimate of the true relationship between the exposure and outcome. It can be addressed through study design (e.g., randomization, matching) or statistical methods (e.g., stratification, regression).

Biostatisticians play a critical role in clinical trials, from designing the trial protocol to analyzing the data and interpreting the results. They ensure the integrity and validity of the trial findings.

Data quality is essential for producing reliable and valid results. Biostatisticians are responsible for ensuring that data are accurate, complete, and consistent.

Bioinformatics is an interdisciplinary field that combines biology, computer science, and statistics to analyze large biological datasets, such as genomic and proteomic data. Biostatistics provides the statistical methods used in bioinformatics.

Survival analysis is a set of statistical methods used to analyze the time until an event occurs, such as death, disease progression, or treatment failure. It is used when the outcome of interest is the time to an event.

Kaplan-Meier curves are graphical representations of survival probabilities over time. They are used to visualize and compare the survival experiences of different groups.

A hazard ratio is a measure of the relative risk of an event occurring in one group compared to another. A hazard ratio of 1 indicates no difference, while a hazard ratio greater than 1 indicates an increased risk, and a hazard ratio less than 1 indicates a decreased risk.

Regression analysis is a statistical method used to model the relationship between a dependent variable and one or more independent variables. It is used to predict outcomes, identify risk factors, and control for confounding variables.

The application of statistical concepts to questions and problems in medicine, public health or biology constitutes biostatistics. The biostatistics discipline offers methods and techniques for gathering and then summarising, analysing and interpreting da

Two main statistical methods are used in data analysis: descriptive statistics, which summarize data from a sample using indexes such as the mean or standard deviation, and inferential statistics, which draw conclusions from data that are subject to rando
