What are the disadvantages of stratified sampling?
Stratified sampling can be complex and time-consuming to implement. It requires detailed knowledge of the population.
Can you explain why it requires detailed knowledge?
Yes, you need to identify and define the strata accurately to ensure that each subgroup is represented properly.
Are there any other drawbacks?
Another drawback is that if the strata are not homogeneous, it can lead to increased variability within the samples.
How does that affect the results?
Increased variability can make it harder to draw reliable conclusions, potentially skewing the results.
Is stratified sampling still worth using despite these disadvantages?
Yes, it can still be beneficial when the population is diverse, as it helps ensure representation of all subgroups.
