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 does control and monitoring mean?
monitering and control is an ICT term monitering and control is an ICT term
What does the convince sample mean?
Nothing, since there is no such term. Check your notes and resubmit your question.
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.
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 happens to the sample mean as the sample size increases?
With a good sample, the sample mean gets closer to the population mean.
What does the term coefficient of variation mean?
The Coefficient of Variation is a ratio showing the degree to which individual points of data in a sample deviate from the mean. It is calculated by taking the standard deviation of the sample and dividing that by the mean of the sample. It can be useful for comparing different data sets because it is a ratio (or percentage) and not an absolute number.
Why is water used as the control sample?
It serves as the negative control
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
When using the distribution of sample mean to estimate the population mean what is the benefit of using larger sample sizes?
The variance decreases with a larger sample so that the sample mean is likely to be closer to the population mean.
A Numerical Measure from a Sample Such as a Sample Mean Is Known?
sample statistic
What does the term pip on cable-vision remote control mean?

What is the difference between calculating the sample mean and the population mean?
You calculate the actual sample mean, and from that number, you then estimate the probable mean (or the range) of the population from which that sample was drawn.
