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?
It serves as the negative control
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?

When anazlyzing a water sample for presence of an ion using precipitation reactions why should the entire sample not be used in the process explain?
You must keep a sufficient amount of sample to repeat analyzes if necessary and also to have a control (archive) sample.
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 are two ways that researcher can avoid a biased sample?
experimental and control groups
