The design of a study defines the study type (descriptive, correlational, semi-experimental, experimental, review, meta-analytic) and sub-type (e.g., descriptive-longitudinal case study), research problem, hypotheses, independent and dependent variables, experimental design, and, if applicable, data collection methods and a statistical analysis ...
Google+. Google+ (sometimes written as Google Plus, stylized as G+ or g+) was a social network that was owned and operated by Google until it ceased operations in 2019. The network was launched on June 28, 2011, in an attempt to challenge other social networks, linking other Google products like Google Drive, Blogger and YouTube.
The design of experiments ( DOE or DOX ), also known as experiment design or experimental design, is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation. The term is generally associated with experiments in which the design introduces conditions ...
Design: A set of experimental runs which allows you to fit a particular model and estimate your desired effects. Design matrix: A matrix description of an experiment that is useful for constructing and analyzing experiments. Design Point: A single combination of settings for the independent variables of an experiment.
Web-based experiments. A web-based experiment or Internet-based experiment is an experiment that is conducted over the Internet. In such experiments, the Internet is either "a medium through which to target larger and more diverse samples with reduced administrative and financial costs" or "a field of social science research in its own right."

A longitudinal study (or longitudinal survey, or panel study) is a research design that involves repeated observations of the same variables (e.g., people) over long periods of time (i.e., uses longitudinal data ). It is often a type of observational study, although it can also be structured as longitudinal randomized experiment.
Design science (methodology) Design science research (DSR) is a research paradigm focusing on the development and validation of prescriptive knowledge in information science. Herbert Simon distinguished the natural sciences, concerned with explaining how things are, from design sciences which are concerned with how things ought to be, [1] that ...
Design-based research (DBR) is a type of research methodology used by researchers in the learning sciences, which is a sub-field of education. The basic process of DBR involves developing solutions (called "interventions") to problems. Then, the interventions are put to use to test how well they work. The iterations may then be adapted and re ...
