Several strategies can be employed to ensure proper sub group representation:
Random Sampling: Using random sampling techniques helps in achieving a representative sample of the population. Stratified Sampling: This involves dividing the population into sub groups and then sampling from each to ensure all groups are represented. Oversampling: In cases where certain sub groups are underrepresented, oversampling can be used to ensure their adequate representation. Weighting: Statistical weighting can adjust for any over- or under-representation in the sample.
