Why is experimental design a key factor in science inquiry?
The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.
What kind of study When performing an experiment to control for confounding variables such as gender the subjects are separated by that possible confounding variable?
The study described is a stratified randomization or stratified design. In this approach, subjects are divided into groups based on the confounding variable (in this case, gender) before random assignment to experimental conditions. This method helps ensure that the potential influence of the confounding variable is balanced across the treatment groups, thereby enhancing the validity of the experiment's results. By controlling for gender, researchers can more accurately assess the effects of the independent variable on the dependent variable.
An experimental design is usually looking to determine?
causation
Why is it necessary to have both an experimental group and a control group?
Having both an experimental group and a control group is essential to establish a baseline for comparison. The experimental group receives the treatment or intervention being tested, while the control group remains unchanged, allowing researchers to identify the effects of the treatment. This design helps isolate the impact of the variable being studied, reducing confounding factors and enhancing the validity of the results. Ultimately, it strengthens the conclusions drawn from the experiment regarding cause and effect.
Should you have more control groups than experimental groups in an experiment?
In an experiment, having more control groups than experimental groups is not a strict requirement; rather, it depends on the specific research question and design. Control groups serve as a baseline to compare the effects of the experimental conditions, so having multiple control groups can help account for variability and confounding factors. However, too many control groups may complicate the analysis and interpretation of results. The key is to balance the number of control and experimental groups to effectively address the research hypothesis while maintaining clarity in the findings.
What is complete randomized design in statistics?
Complete randomized design is a type of experimental design where treatments are randomly assigned to experimental units. This design allows for unbiased comparisons between treatments and is useful for studying the effects of different factors on an outcome of interest. Randomization helps minimize the effects of confounding variables and increases the internal validity of the study.
What is the term when a variable unaccounted for in an experiment effects the results in experimental psychology?
confounding variable
Write short note on experimental reserach design?
Experimental research design involves manipulating one or more variables in a controlled setting to observe the effect on the dependent variable. It allows researchers to establish cause-and-effect relationships by controlling for potential confounding variables. This design is characterized by random assignment of participants to different conditions and the use of control groups to minimize bias and increase the internal validity of the study.
What should an experimental design frame look like?
An experimental design framework typically includes a clear statement of the research question, a detailed description of the experimental procedures to be followed, identification of the variables to be manipulated and measured, a hypothesis to be tested, and a plan for statistical analysis of the data collected. It should also include information on the control group, randomization, and any potential confounding variables that need to be addressed.
What are the strengths of an experimental design?
a strength of an experimental design can be the sample size. having a large sample size eliminates some falty results or fulked results. also controlling all varibles except the independent is importent

Can you give you a sentence using experimental design?
The next car show will have an example of our experimental design.
What should be included in an experimental design because of the way dated analyzed using statistics?
An experimental design should include clearly defined variables, such as independent and dependent variables, to facilitate accurate statistical analysis. Randomization is crucial to minimize bias and ensure that results are not influenced by confounding factors. Additionally, a well-defined sample size is necessary to achieve statistical power, allowing for reliable conclusions. Finally, control groups should be established to compare the effects of the experimental treatment effectively.

How is a quasi-experimental design different from a pure experimental design?
pure -absolute control Quasi -have some control
What are the advantages and disadvantages of ex post facto research?
advantages:its ideal for testing demographic variables which cannot be manipulated. like a non-experimental design it doesn't require much to collect data, but just merely shows effects of a presence or absence of an Independent variable on a Dependent variable.disadvantages:it cannot acquire as much data as an experimental design, the levels of the "IV" are already established. If anything it tries to be an experimental design but it cannot.
