This article provides background information related to fundamental methods and techniques in biostatistics for the use of postgraduate students.
Using the tools of statistics, biostatisticians help answer pressing research questions in medicine, biology and public health, such as whether a new drug works
Population Parameters Versus Sample Statistics
As noted in the Introduction, a fundamental task of biostatistics is to analyze samples in order to make inferences about the population from which the samples were drawn.
To illustrate this, consider the population of Massachusetts in 2010, which consisted of 6,547,629 persons.
One characteristic (or variable) of potential interest might be the di.
What are other plots used in biostatistics?
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.

What is the difference between data and a variable in biostatistics?
Our goal here is to present the concepts and look at the applications from the point of view of the applied user of biostatistics.
Data constitute the raw material for statistical work.
They are records of measurement or observations or simply counts.
A variable refers to a particular character on which a set of data are recorded.
