Biostatistics (also known as biometry) is a branch of statistics that applies statistical methods to a wide range of topics in biology.
It encompasses the design of biological experiments, the collection and analysis of data from those experiments and the interpretation of the results..
Data are pieces of information about individuals organized into variables.
By an individual, we mean a particular person or object.
By a variable, we mean a particular characteristic of the individual..
Data types are crucial because statistical procedures can only be applied to specific data kinds.
Continuous data must be analyzed differently from categorical data, or else the analysis will be incorrect.
Knowing what kind of data you're working with allows you to select the best technique of analysis..
Many other plots are used in biostatistics for depicting data distributions, time trends in observations, relationships between two or more variables, exploring goodness-of-fit to hypothesized data distributions and drawing inferences by comparing data sets.
We will get introduced to select other plots in subsequent modules in this series.
