What else can I help you with?
In an experimental design the variable the researcher has control over and that is different for the treatment and control groups is called the?
Explanatory variable apex
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.
The goal of using replication control randomization and blindness in experimental design is to compeletey eliminate bias from an experiment?
False
What would most likely occur if an experimental design specifies only test group?
The experiment would lack a control group
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.
How is a quasi-experimental design different from a pure experimental design?
pure -absolute control Quasi -have some control
The purpose of blocking in experimental design is?
the control for multiple variables in a experiment
In an experimental design the variable the researcher has control over and that is different for the treatment and control groups is called the?
Explanatory variable apex
What is expost facto research design and the different conditions in using it?
It involves assignment of subjects to experimental group and control group. it also involves subjecting the experimental group to experimental treatment. it can be defined as an "After the fact design". it is a form of design in which a particular characteristics of a given group is investigated so as to identify it anticidents.
What principles of experimental design ensures that the explanatory variable and not some variable over which the experimenter has no control is causing observed changes in the res?
Control
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.
The goal of using replication control randomization and blindness in experimental design is to compeletey eliminate bias from an experiment?
False
Can you give you a sentence using experimental design?
The next car show will have an example of our experimental design.
Are the control and experimental groups are designed to be identical?
In an ideal experimental design, the control and experimental groups are designed to be as similar as possible, with the only difference being the specific treatment or intervention that the experimental group receives. This helps to isolate the effect of the treatment and minimize the impact of other variables on the outcome of the study.
Which term describes a type of independent variable used to compare differences in dependent varables?
experimental control

Why is experimental control needed in experiments?
The experimental control is what you compare your experimental data with. Without the control, you can't tell if the variable you are testing is what is causing your results.
