In descriptive studies, a variable is any characteristic, trait, or feature that can be measured or observed and can vary among subjects or over time. Variables can be classified into different types, such as categorical (e.g., gender, ethnicity) or continuous (e.g., age, income). Descriptive studies often aim to summarize and describe the characteristics of a population based on these variables without manipulating them. This helps in understanding patterns and trends within the data.
A manipulated variable, also known as an independent variable, is the factor in an experiment that is intentionally changed or controlled by the researcher to observe its effect on another variable. This variable is crucial for establishing cause-and-effect relationships in scientific studies. By altering the manipulated variable, researchers can measure how it impacts the dependent variable, which is the outcome being tested.
A valid variable name must start with a letter (a-z, A-Z) or an underscore (_) and can be followed by letters, digits (0-9), or underscores. It cannot contain spaces, special characters, or begin with a digit. Additionally, variable names should not be a reserved keyword in the programming language being used. It's also a good practice to use descriptive names that convey the purpose of the variable.
In research and experimentation, "independent" or "manipulated" refers to the variable that is intentionally changed or controlled by the researcher to observe its effect on another variable. This variable is considered independent because its variation is not influenced by other variables in the experiment. It is crucial for establishing cause-and-effect relationships in scientific studies.
Variables are the basis of a scientific experiment. When the scientist is carrying out his procedure, he is actually altering a variable, called the independent variable. Unless he just likes playing with chemicals, he is likely attempting to get a result, and he does this by using measurements of the dependent variable, which has changed because of the manipulation of the independent variable. Identifying the variables becomes very important when formulating more complicated studies, and becomes the bread and butter of psychological experiments.
The descriptive method of a thesis uses groups of individuals, phenomenon's, and ideas or theories. The main focus of a descriptive thesis is on providing and analyzing facts.
Descriptive studies for case-control.
A variable is a measured quantity In the context of survey research, a descriptive variable is one that is just to be reported on, with no conclusions drawn about influence or causality eg. place of birth may be a descriptive variable where we just thought was something interesting to put in the report.
Descriptive studies can be both qualitative and quantitative in nature. Qualitative descriptive studies focus on exploring and understanding phenomena through words and descriptions, while quantitative descriptive studies involve collecting and analyzing numerical data to describe a phenomenon.
The colour of your hair, the district that you live in, your gender.
Descriptive studies are designed to answer questions related to the "who," "what," "where," and "when" of a phenomenon. They aim to provide a detailed account of characteristics or behaviors within a specific population, such as prevalence rates, demographic information, and trends over time. Unlike experimental studies, descriptive studies do not assess causal relationships but focus on outlining patterns and associations in the data.
A control variable is a variable that is held constant in a research analysis.
The different types of scientific investigations include descriptive studies, experimental studies, observational studies, and theoretical studies. Descriptive studies aim to describe a phenomenon, experimental studies involve manipulating variables to test hypotheses, observational studies involve observing and analyzing data without intervening, and theoretical studies involve developing and testing models or theories.
A variable that is not numerical but descriptive or categoric. Answers to what colour is your car, what is your favourite fruit/ band/ movie, your gender: male/female,
Descriptive statistics label, name, or give information about a variable. Inferential stats are inferred from a smaller data set to be valid for the whole population.

The different types of descriptive research designs used in social science research include observational studies, surveys, case studies, and correlational studies. These designs aim to describe and analyze the characteristics of a population or phenomenon without manipulating variables.
