What else can I help you with?
Randomization in an experiment means that the experimental units or subjects have been assigned to their respective test groups randomly?
True
Is randomization in an experiment means that the experimental units or subjects have been assigned to their respective test groups randomly?
yes, it is.
Why is a variable used in an experiment?
Because it's an experiment not a replication...
In an experiment what is the experimental data compared to?
In an experiment there is one thing that it is compared with experimental data. This is when the end results.The experiment data is compared to one thing. It is compared to the end results.
In a controlled experiment what is the experimental group compared to?
The control group.
Is randomization in an experiment means that the experimental units or subjects have been assigned to their respective test groups randomly?
yes, it is.
Randomization in an experiment means that the experimental units or subjects have been assigned to their respective test groups randomly?
True
Randomization in an experiment means that the experimental units or subjects are selected as a simple random sample from the whole population under study?
False
What principle experimental design reduces errors due to chance by repeating an experiment on different subjects under different conditions?
Replication
Randomization in an experiment ensures that any difference in the responses of the experiment groups is due to the treatment?
true
In science What do you call if someone repeats your experiment and gets a similar result?
When someone repeats your experiment and obtains a similar result, it is referred to as experimental replication. This strengthens the validity and reliability of the original findings.
Randomization in an experiment reduces bias between the treatment and control groups?
True
What are the main concepts of experimental design?
The main concept of Experimental Design (Also known as DOE) is designing of information - gathering exercises where variation is present, whether under full control of the experimenter or not.
What are the three characteristics of a well designed experiment?
Control: The experiment should control for variables that could affect the outcome, ensuring that only the manipulated variable is influencing the results. Randomization: Participants should be randomly assigned to different conditions to minimize bias and ensure results are generalizable. Replication: The experiment should be able to be repeated by other researchers to verify the results and ensure reliability.

What is a experimental sample?
An experimental sample is an experiment that is just a sample of what you are looking for.
Are non experimental and quasi-experimental the same?
No. Non-experimental is NOT experimental . Quasi- experimental is fake or partially experimental . Not following the protocols of a true experiment .
