When performing an experiment it is very important to have a control set. It is important to have a control set because it ensures that the experiment can be repeated as many times as necessary.
all subjects receive treatment's
Observation and record keeping are important as you will need to redo an experiment many times to prove that it actually works.
why is it important to identify errors in an experiment
Test groups should be as large as possible to eliminate the influence of undetected differences in the test subjects.

In Solomon Asch's experiment, approximately 75% of the subjects conformed to the group's incorrect answer at least once, showing the powerful influence of group pressure on individual decision-making.
all subjects receive treatment's
an experiment where the subjects know what is going on. they are not tricked or fooled with any tactics to increase validity such as placebos etc.
Observation and record keeping are important as you will need to redo an experiment many times to prove that it actually works.
science is a really fun subject, you get to experiment!
why is it important to identify errors in an experiment
More than likely not but it depends on how many credits you had before you entered the 10th grade and how many subjects you had during the 10th grade. More important than how many subjects you failed is how many you passed.
Test groups should be as large as possible to eliminate the influence of undetected differences in the test subjects.
the control group
The matched subject because the experiment involves pairs which halves the df.
Because then the grouping is (technically) not random. In order for an experiment to yield proper results, the grouping must be random. If the researcher assigns subjects to groups in the order in which they arrive, then the randomness of the experiment is not present. cw: There are experiments on experiments that show that the first half of subjects are different from the second half of subjects. Why is another question. So you should randomize the allotment of subjects to treatments (groups).
