It allows a population to be sampled at a set interval called the sampling interval. Stratified Sampling - Describes stratified random sampling as sampling method. But the method has some disadvantages. This is because less time is used to gather data. Cluster Sampling It's often used to collect data from a large, geographically spread group of people in national surveys. pros: easier to choose all members randomly from smaller clusters to represent the pop. We tolerate this kind of Organic Food Pros graphic could possibly be the most trending topic later than we share it in google lead or facebook. Simple: It is easy to implement k-means and identify unknown groups of data from complex data sets. Stratified random sampling has advantages when compared to simple random sampling. An element of randomness is introduced by introducing random numbers to pick up the unit with which to start. When the members of the population are convenient to sample. Convenience sampling pros 1. There are various pros and cons for cluster sampling - from data collection to difference in clusters. The United States Census Bureau alone conducts more than 130 surveys a year to ensure communities are receiving the resources and services they need to thrive. Not suitable for large sample Pros of Sampling. Stratified Random Sampling helps minimizing the biasness in selecting the samples. Such type of sampling is known as systematic sampling.
