Astrostatistics is an interdisciplinary field that combines statistical methods with astrophysics and astronomy. The goal of astrostatisticians is to develop and apply statistical techniques to analyze astronomical data. This is essential because astronomical datasets are often vast and complex, involving large-scale surveys, time-series data from telescopes, and simulations of cosmic phenomena. Astrostatisticians work on various topics, including: 1. **Data analysis**: Extracting meaningful information from noisy and high-dimensional data.

Biostatisticians are professionals who apply statistical methods and principles to the field of biology, medicine, and public health. Their work includes designing studies, analyzing data, and interpreting results in a way that informs health-related decisions, advances scientific knowledge, and contributes to the development of new medical treatments and public health policies.

Computational statisticians are professionals who apply computational techniques and algorithms to solve statistical problems. Their work often involves the development and implementation of statistical methods using programming and computational tools, allowing them to analyze complex datasets and perform simulations that would be impractical or impossible using traditional analytical methods. Key responsibilities of computational statisticians may include: 1. **Data Analysis**: Implementing statistical models to analyze large datasets, often in fields such as bioinformatics, machine learning, or social sciences.

Data miners, in the context of data science and analytics, refer to professionals or automated systems that extract useful and actionable insights from large sets of data. The process of data mining involves various techniques from statistics, machine learning, and database systems to identify patterns, correlations, and trends within data that can inform decision-making, predict future outcomes, or reveal hidden relationships.

Pollsters are individuals or organizations that conduct surveys and polls to gather information about public opinion on various issues, candidates, or events. They often use statistical methods to design their surveys, select representative samples of the population, and analyze the results to provide insights into how people think and feel about certain topics. Pollsters play a significant role in political campaigns, market research, and social science research by helping to gauge voter preferences, identify trends, and inform decision-making processes.

Spatial statisticians are professionals who specialize in the analysis of spatial data, which refers to data that has a geographical or spatial component. This field combines statistical methodology and geographical concepts to analyze patterns, relationships, and phenomena that vary across space. Key aspects of what spatial statisticians do include: 1. **Data Collection and Management**: They often work with various types of spatial data, including point data (e.g., locations of incidents), areal data (e.g.

Sports statisticians are professionals who specialize in the collection, analysis, and interpretation of data related to sports and athletic performance. Their work involves a variety of tasks, including: 1. **Data Collection**: Gathering statistics from games, matches, and competitions. This can include player performance metrics (e.g., points scored, assists, rebounds), team statistics (e.g., win-loss records, scoring averages), and game situational data (e.g., time of possession, shots on goal).

Survey methodologists are specialists who focus on the design, implementation, and analysis of surveys. They employ statistical principles and research methodologies to ensure that data collected through surveys are reliable, valid, and representative of the population being studied. Their work involves several key areas: 1. **Survey Design**: This includes selecting appropriate methodologies (e.g., online surveys, telephone interviews, face-to-face interviews) and developing effective questionnaires that minimize bias and lead to high-quality data collection.
