No. Unless there are other reasons, the proportion of each stratum that is sampled (the sampling fraction) should all be equal.

What things might influence the prediction while taking a sample?

Some factors that might influence the prediction while taking a sample include the size of the sample, the representativeness of the sample compared to the population, the variability within the sample, and the method of sampling used. These factors can impact the accuracy and reliability of the prediction based on the sample.


What is sample method?

Data gathered in two different samples in such a way that there is a matching of the first sample data drawn and a corresponding data value in the second sample data. For example, compare two sample means, one for the first exam of the semester and the second for the second exam of the semester, match via the student taking each test.


What is the Difference between attribute and variable sampling?

The main difference in taking the samples is that for a variable sample, measurements of a characteristic of interest are taken, and for an attribute sample, one counts the number of units having or not having specific properties (mostly good/bad or number of flaws). Generally, attribute samples are much larger than variable samples and to be useful, need to be very large, when the proportion of bad units (or flaws) is very small.

Can a company take a urine sample tell you that they are testing for blood sugar and instead test for drugs such as Marijuana?

Explain how you could create a distribution of means by taking a large number of samples of four individuals each?

As the sample size increases, and the number of samples taken increases, the distribution of the means will tend to a normal distribution. This is the Central Limit Theorem (CLT). Try out the applet and you will have a better understanding of the CLT.


Taking blood samples from a central line?

yes


What is Dependent Sampling method?

Data gathered in two different samples in such a way that there is a matching of the first sample data drawn and a corresponding data value in the second sample data. For example, compare two sample means, one for the first exam of the semester and the second for the second exam of the semester, match via the student taking each test.


Does getting your iron tested show any medications you are taking?

Not usually. The testing laboratory gets hundreds of samples per day - they normally only test samples for the specific component the doctor has requested. However - if a sample gives an abnormal result, re-testing might show up other components - which will be reported back to your doctor.
