Strategies for Determining Sample Size Sample Size for finite population For finite population sample size is given byWhere. When this formula is applied to the above sample we get Equation 6.
In the case of small-scale running events with N By adding the required minimum sample size for each category of running events 2323 2 351 2 363 2074 a grand total sample size of.
This formula was used to calculate the sample sizes in Tables 2 and 3 and is shown below. The sample size for the chosen parameters should be 16641 which is a very large sample. Therefore the sample size is an essential factor of any scientific research. A 95 confidence level andP5are assumed for Equation 5.
