Example 9.10 Selecting Equal-Sized Samples from Different Groups
Randomly select the same number of observations from different groups in a data set. Do not allow an observation to be selected more than once. This method is commonly referred to as stratified random sampling without replacement and with equal allocation.
Additionally, create replicate samples by repeating the process of randomly selecting the same number of observations from different groups.
