Social media are computer-mediated technologies that facilitate the creation and sharing of information, ideas, career interests and other forms of expression via virtual communities and networks.

A field of applied statistics of human research surveys, survey methodology studies the sampling of individual units from a population and the associated survey data collection techniques, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys.

Survey methodology includes instruments or procedures that ask one or more questions that may, or may not, be answered.

An opinion poll, sometimes simply referred to as a poll, is a human research survey of public opinion from a particular sample.

Opinion polls are usually designed to represent the opinions of a population by conducting a series of questions and then extrapolating generalities in ratio or within confidence intervals.

Analysis of data, also known as data analytics, is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, suggesting conclusions, and supporting decision-making.

Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, in different business, science, and social science domains.

In mathematical modelling and statistical modelling, there are dependent and independent variables.

The models investigate how the former depend on the latter.

The dependent variables represent the output or outcome whose variation is being studied.

The independent variables represent inputs or causes, i.e. potential reasons for variation.

Models test or explain the effects that the independent variables have on the dependent variables.

Sometimes, independent variables may be included for other reasons, such as for their potential confounding effect, without a wish to test their effect directly.
