Randomization in an experiment reduces bias between the treatment and control groups?
True
A condition applied to the experimental units involved in an experiment?
A treatment
What are positive and negative controls in an experiment?
Positive controls : an experimental treatment that will give the desired result Negative controls: An experimental treatment that will NOT give the dersired result.
What is a repetition of an experiment?
A repetition of an experiment is used to provide reliability. Just in case your result was a coincidence or caused by another factor not your treatment. Examples of repetition can be having more than one thing in each treatment. E.g. Having four plants with high clay soils in case something unexpected happens. Like one doesn't germinate. Another example could be that you do the experiment a couple of times so that you are sure that your results is because of the variable/treatment you are testing. Hope this helps.
Is the dependent variable in an experiment the factor that may be influenced by the experimental treatment?
yes It sounds like you have a good handle on this based on the question..
Randomization in an experiment reduces bias between the treatment and control groups?
True
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.
What is the difference between factor and treatment in a experiment?
treatment is a factor in which a researcher will apply to an experimental unit and collect the data from the same. factor is a material used by researcher in an experiment in the field .
What statement of no difference in experimental treatment?
When setting up an experimental procedure one prepares a control treatment as well as one or more experimental treatments. At the end of the experiment, if there is no difference between the experimental and control groups the experiment is typically said to be not conclusive. With a typical set-up, this result generally fails to lead to a rejection of the null hypothesis.
In a controlled experiment what group recevies some type of treatment?
An experimental group is the group in an experiment that receives some type of treatment. The control group in an experiment receives no treatment. And, in conclusion, sometimes it might not work so be careful!!! :)
What is group that receives no treatment in an experiment?
the control.
What is the difference between experimental group and controlled group?
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.

What are constants in experiment?
they are the things that don't change in an experiment/ that don't receive any special treatment.
Which treatment of allergic responses involves gradually developing immunity to offending allergens?
immunotheraphy
Entries for each outpatient record form should contain which one what responses?
The date of treatment
In an experiment a group that receives treatment is called what?
Experimental group
