Local control in experimental design refers to techniques used to minimize the effects of variability within the experimental units by controlling for specific factors. This can include randomization, blocking, or using matched pairs to ensure that differences in treatment effects are more likely attributable to the treatments themselves rather than extraneous variables. By focusing on local control, researchers can improve the precision and reliability of their results, leading to more valid conclusions about the treatment effects being studied.
What else can I help you with?
What is the name of research design that uses control group as experimental group after intervention has been finished in first experimental group?
The research design you're referring to is known as a "cross-over design." In this design, participants are exposed to both the experimental and control conditions, with the control group receiving the intervention after the initial phase is completed. This allows researchers to compare the effects of the intervention within the same subjects, enhancing the reliability of the findings while controlling for individual variability.
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
The goal of using replication control randomization and blindness in experimental design is to compeletey eliminate bias from an experiment?
False
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 would most likely occur if an experimental design specifies only test group?
The experiment would lack a control group
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

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

False

The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.
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.
Can you give you a sentence using experimental design?
The next car show will have an example of our experimental design.
Which term describes a type of independent variable used to compare differences in dependent varables?
experimental control
