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.
How does randomization in an experiment combat response bias?
Response bias cannot be eliminated, but it should cancel out between the treatment and control groups.
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.
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
Randomization in an experiment reduces bias between the treatment and control groups?
True
What are the main concepts of experimental design?
The main concepts of experimental design include randomization (assigning subjects randomly to groups), control (keeping all variables constant except for the one being tested), replication (repeating the experiment to ensure results are consistent), and blocking (grouping subjects with similar characteristics to reduce variability). These concepts help ensure that experiments are valid, reliable, and capable of drawing meaningful conclusions.

What is a experimental sample?
An experimental sample is an experiment that is just a sample of what you are looking for.
What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
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 .
Why must controls be used in fertilizer experiment?
to elliminate soures of error
