Statistics is the branch of mathematics that deals with collecting, organizing, analyzing, interpreting, and presenting data. It is customary to start with a statistical population or model to be investigated when applying statistics to a scientific, industrial, or social problem. Populations can include many people or things, such as “all individuals living in a country” or “every atom in a crystal.” Statistics is concerned with all aspects of data, including data collection planning in terms of survey and experiment design.

When census data is unavailable, statisticians use unique experiment designs and survey samples to obtain data. Representative sampling ensures that inferences and conclusions drawn from the sample may be extrapolated to the entire population. An experimental study is collecting measurements of the system under investigation, changing it, and then taking more measurements using the same technique to see if the modification has changed the measurements’ results. An observational study, on the other hand, does not entail any experimental modification.

In data analysis, there are two major statistical methods: descriptive statistics, which use indices like the mean or standard deviation to describe data from a sample, and inferential statistics, which derive inferences from data susceptible to random fluctuation (e.g., observational errors, sampling variation). Descriptive statistics are most often concerned with two properties of a distribution (sample or population): central tendency (or location) seeks to characterize the distribution’s central or typical value, whereas dispersion (or variability) seeks to characterize the extent to which members of the distribution depart from its center and each other. Probability theory, which deals with examining random occurrences, is used to make inferences based on mathematical statistics.
