What statement best describes an independent variable Weegy?

What statement best describes an independent variable Weegy?

The factor that’s changed by the experimenter and impacts the dependent variable best describes an independent variable.

What is the best description of a dependent variable?

The dependent variable is the variable that is being measured or tested in an experiment. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.

What is the dependent variable in the graph?

The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).

Can you have two independent variables?

Can I include more than one independent or dependent variable in a study? Yes, but including more than one of either type requires multiple research questions. Each of these is a separate independent variable. To ensure the internal validity of an experiment, you should only change one independent variable at a time.

What is independent variable in quantitative research?

Independent variables (IV) are those that are suspected of being the cause in a causal relationship. If you are asking a cause and effect question, your IV will be the variable (or variables if more than one) that you suspect causes the effect.

Are independent variables qualitative or quantitative?

Some examples of quantitative variables are height, weight, and shoe size. In the study on the effect of diet discussed above, the independent variable was type of supplement: none, strawberry, blueberry, and spinach. The variable “type of supplement” is a qualitative variable; there is nothing quantitative about it.

Do all types of quantitative research make use of independent variables?

The foundations of quantitative research are variables and there are three main types: dependent, independent and controlled. The researcher will manipulate an independent variable in an effort to understand its effect on the dependent or controlled variable.

How do you identify quantitative research?

Identifying Quantitative Research – Example

1. the goal of the study was examining relationships between several variables.
2. the researchers used statistical methods (logistic regression models)
3. subjects completed questionnaires.
4. the study included a large number of subjects.

What is the aim of quantitative research?

What is the purpose of quantitative research? The purpose of quantitative research is to generate knowledge and create understanding about the social world. Quantitative research is used by social scientists, including communication researchers, to observe phenomena or occurrences affecting individuals.

Where is quantitative research used?

Quantitative Research is used to quantify the problem by way of generating numerical data or data that can be transformed into usable statistics. It is used to quantify attitudes, opinions, behaviors, and other defined variables – and generalize results from a larger sample population.

Why is quantitative research expensive?

Quantitative research is difficult, expensive and requires a lot of time to be perform the analysis. So, as to achieve in-depth responses on an issue, data collection in quantitative research methodology is often too expensive as against qualitative approach.

What are characteristics of quantitative research?

Characteristics of Quantitative Research

• The data is usually gathered using structured research instruments.
• The results are based on larger sample sizes that are representative of the population.
• The research study can usually be replicated or repeated, given its high reliability.

What are the 6 kinds of quantitative research?

The following precedes the different types of Quantitative research types with the description of each.

• Survey Research. Survey Research is the most elementary tool for all sorts of quantitative research techniques.
• Descriptive Research.
• Experimental Research.
• Correlational Research.
• Casual-Comparative Research.
