How do a control sample and an experimental sample differ from each other?
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
What is a sample of control risk?
risk control is when cows are born in the ocean risk control is when cows are born in the ocean
What are two ways that researcher can avoid a biased sample?
experimental and control groups
What is the Relationship between Acceptable risks of assessing control risk too low and sample size?
Acceptable Risk of Assessing Control Risk too Low (ARACR) is inversely related to Sample Size. Consider this: If we do not want to allow any room for error in judgment (meaning we lower the ARACR), we must increase the sample size to ensure our results have a smaller margin of error. (Source: "Auditing and Assurance," 14th ed., Arens Elder Beasley, 491)
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
What does control as an experiment means?
A control sample or control group is used to compare with the experimental group or sample. The control sample ideally, should be exactly the same as the experimental sample except that you don't give your experimental treatment to the control sample. Afterwards you compare the 2 samples to see if your experimental treatment had any kind of effect. The control is like a reference point.

Why is water used as the control sample?
Water is often used as a control sample because it is a neutral substance that does not interfere with the experiment. By comparing the results from the experimental samples to the control sample of water, researchers can more accurately determine the effects of the variables being tested. Additionally, water is readily available, inexpensive, and easily controlled for consistency.
What does the term control sample mean?
A 'control' is a sample with a known outcome. By testing the control at the same time, with the same operator, under the same conditions as the 'test sample' one builds validity into the test result, assuming of course, that the result gives the expected outcome.
What is a sample that is treated exactly like all other experimental groups that the variable is not applied to it is a?
Again another of my homework questions and i think its control
Why do you need to perform each of the tests on a known sample as well as on your unknown sample?
it is need so as a control.
What is a sample of control risk?
risk control is when cows are born in the ocean risk control is when cows are born in the ocean
Why control sample kept one years after expiry?
awesome
Why is a control group necessary in a scientific investagation?
A control group is needed to see how the sample responds under normal conditions
What is the difference between quota and stratified sampling?
The main difference between the quota and stratified sampling is that in the stratified sampling the researcher can not select the individuals to be included in the sample (he doesn't have control over who will be in the simple), but in the quota sampling the researcher has control over who will be in the sample (he can contact certain people and include them in the sample).
What are two ways that researcher can avoid a biased sample?
experimental and control groups
What is the purpose of a control sample that is known to be from bighead carp in Edna surveillance?
to see if samples contain the target DNA
