"Biostatistics is a branch of statistics that applies statistical methods to a wide range of topics in biology."
The application of statistical methods to biological research and data analysis.
Probability theory: The study of random events and their likelihood.
Probability distributions: Mathematical models used to represent the behavior of random variables.
Descriptive statistics: The collection, analysis, and interpretation of numerical data.
Inferential statistics: The application of statistical techniques to estimate and test hypotheses.
Sampling theory: The study of how to estimate population parameters based on data from a sample.
Hypothesis testing: The process of evaluating whether a hypothesis is true or false based on statistical evidence.
Confidence intervals: The range of values around a point estimate that is likely to contain the true population parameter.
Regression analysis: A statistical method used to explore the relationship between two or more variables.
Survival analysis: A statistical method used to analyze time-to-event data.
Epidemiology: The study of the distribution and determinants of health and disease in populations.
Biostatistical methods for clinical trials: Methods used to design and analyze clinical trials to test the safety and efficacy of new treatments.
Bayesian methods: A statistical approach that uses prior knowledge and probability distributions to update beliefs about the likelihood of an event.
Genetic association analysis: A statistical method used to identify genetic variants that are associated with a particular disease or phenotype.
Meta-analysis: A statistical method used to combine the results of multiple studies to obtain a more precise estimate of a treatment effect.
Longitudinal data analysis: A statistical method used to analyze data collected over time.
Machine learning: A set of algorithms and statistical models that allow computers to learn patterns in data without being explicitly programmed.
Big Data analytics: Methods for processing and analyzing vast amounts of data.
Data visualization: Techniques for presenting data visually to help understand patterns and relationships in the data.
Statistical software packages: Tools for implementing statistical methods and analyzing data, such as R, SAS, and STATA.
Ethical issues and principles in biomedical research: The principles of bioethics, including informed consent, confidentiality, and respect for human subjects, are critical for data collection in biostatistical research.
Descriptive Biostatistics: It is the basic form of biostatistics that describes the characteristics of a population or sample. This type of biostatistics includes measures of central tendency, variability, shape of a frequency distribution, and correlation.
Statistical Inference: It deals with making predictions or drawing conclusions about a population from a sample. It involves hypothesis testing, estimation and confidence intervals.
Regression analysis: It is a statistical method used to examine the relationship between two or more variables. It helps us to estimate the association between variables, and to predict the outcome for a new set of variables.
Survival analysis: It is the study of predicting the time to an event or the probability of an event happening. It is commonly used in clinical trials to predict the survival rate of patients.
Longitudinal analysis: It refers to the analysis of data collected over time from the same sample. It helps to identify the trends and changes in a particular population over time.
Bioinformatics: It is the use of computer algorithms and software to analyze and understand biological data. It is used in genomics, proteomics, and other biological research fields.
Epidemiology: It is the study of the distribution and determinants of health-related events or conditions in populations. It helps in identifying the cause and risk factors of diseases and designing intervention strategies.
Sample size calculations: It is the process of determining the number of participants required in a study to achieve reliable results.
Experimental design: It is a framework for planning experiments that help to identify the effects of different variables on the outcome. It helps in conducting studies that are more controlled and generate more reliable results.
Meta-analysis: It is the statistical analysis of data from multiple studies to generate a combined estimate of the effect size. It helps to examine the overall effectiveness of an intervention or treatment.
