What is a sample study?
sample is the population we make our study about them.
What is the purpose of using measures of central tendency and dispersion?
Given that the study manager wants the QC efforts to be focused on selecting outlier values, whose method is a better way of selecting the sample
What effect does non-random sample have on what you can say about the results of a study?
It means that the results of the study cannot be claimed to hold for the entire population from which the sample was drawn. The researchers can only claim that their results hold for the individuals selected into their sample.
Does the size of a sample affect the values of the frequency table?
Yes. If the sample is a random drawing from the population, then as the size increases, the relative frequency of each interval from the sample should be a better estimate of the relative frequency in the population. Now, in practical terms, increasing a small sample will have a larger effect than increasing a large sample. For example, increasing a sample from 10 to 100 will have a larger effect than increasing a sample from 1000 to 10,000. The one exception to this, that I can think of, is if the focus of the study is on a very rare occurrence.

An experiment involves selecting a random sample of 256 middle managers for study One item of interest is annual income The sample mean is computed to be 35420 and the sample standard deviation is 205?
The deviation would be how much off it would be off. Since this is a sample, it is impossible to get completely accurate results.
What is a sample of a population that has been selected using a pattern?
A sample of a population that has been selected using a pattern is when a researcher selects every 10th person from a list or sampling frame. For example, if a researcher wants to study the attitudes of employees in a large company, they may select every 10th employee from the company directory. This method ensures a systematic pattern in selecting the sample.
What is the difference between a panel study and a cohort study?
A panel study uses a representative sample, whereas a cohort study uses a sample with predetermined common characteristics.
