What Should Be The Minimum Sample Size. Some publications using cluster analysis mention O2 m where m is the number of attributes and O is the number of objects or observations as a rule of thumb for the size of the dataset. 7 min read Finding the perfect sample size for statistically sound results is an age old problem.
A good maximum sample size is usually. Using the sample size formula you calculate the sample size you need is which you round up to 211 students you always round up when calculating n. The minimum sample size recommendation of 100 comes from simulation studies eg Anderson.
Why is 30 the minimum sample size.
Some publications using cluster analysis mention O2 m where m is the number of attributes and O is the number of objects or observations as a rule of thumb for the size of the dataset. Which would be rounded up to 97 because the obtained value is the minimum sample size and sample sizes must be integers and must lie on or above the calculated minimum. This minimum sample size calculator computes the minimum sample size. The calculator will spit out your sample size.
