    Additional types of sampling
    Cluster Sampling:
    Cluster sampling is like picking groups or clusters of individuals from a larger population instead of selecting individuals one by one. Imagine you have a big box of candies, and instead of picking candies individually, you divide the candies into small bags (clusters) first. Then, you randomly choose a few bags, and all the candies in the selected bags become your sample. It's an efficient way to sample when it's hard or expensive to reach individuals directly.
    2.Judgmental Sampling (Purposive Sampling):
    Judgmental sampling is when you choose specific individuals or groups deliberately based on your judgment or knowledge of the population. For example, if you want to study the opinions of experts in a field, you might handpick experts you know and include them in your sample. This method can be useful when you need specialized insights, but it may introduce bias if your judgment is subjective.
    3. Snowball Sampling:
    Snowball sampling is a method used when it's challenging to identify or reach individuals directly. It's like starting with a small snowball and rolling it downhill, and as it rolls, it picks up more snow and becomes bigger. Similarly, you begin by finding a few initial participants (who are part of the target group), and then you ask them to refer others who fit the criteria. This process continues, and your sample grows like a snowball. It's often used in studies involving hard-to-reach or hidden populations.

    1) Exit Poll - Random Sampling
    2) Disease Information - Voluntary Response Sampling
    3) Household expenditures - Stratified Sampling if Women or Voluntary Response Sampling if the situation requires the conclusion from only married people....
    please correct me if am wrong and your valuable feedback would strengthen my knowledge, thanks for the wonderful video.

    Generally we use simple random sampling when we have homogeneous type of data. When we have heterogeneous type of data then we divide these data into varipus statras and then select observations from strats randomly ..then this procedure is called stratified random sampling.

    In stratified random sampling our objective is to make strats homogeneous as much possible then we simply use simple random sampling.

      Yes , your idea is good we can use strata in this case but at last we will have to go with simple random sampling . First strata then random .
