sample size is required for a two-tailed test than for a one-tailed test. Different sample size formula are required depending on the research underlying statistical test, for example a t-test for comparing two means, a z-test for comparing two proportions or a log-rank test in time to event analyses. The sample size formula provided in this paper. For larger research jobs, a survey sample can range from 30 to for a population of 30 lakhs to 1 million, although samples can be bigger than this. The determination of a sample size is dependent on the study parameters and expected confidence with which the results need to be obtained. How to Calculate a Sample Size It is fairly easy to determine your desired sample size. Formulas found in textbooks often appear very intimidating. However, they can be broken down and simplified if you are familiar with the above terms. Scott Smith, Ph.D., presents a rather simpler version. His formula for size calculation goes as follows.

A crucial issue that affects sampling of data for research is determination of sample size. A larger sample will be a better depiction of the target group. Sample size estimates are based upon assumptions that might not always be correct. The numbers collected need to be tested statistically once the sample is completed by comparing sample.

The sample size for the chosen parameters should be 16,, which is a very large sample. To make it a more realistic number, you might consider reducing your confidence level and margin of error. If you reduce it to 95% confidence level and 5% margin of error, you get a more manageable participants, which you round up to

Sampling: The Basics

Sample is a smaller version of the entire population that your dissertation research is about. Sample size is the number of subjects in your study. Although these two terms can be simply and easily defined, there are many important sampling questions that you will have to consider as you plan your dissertation research.
