What else can I help you with?
Mention different types of sampling in statistics.?
Simple Random Sample Stratified Random Sampling Cluster Sampling Systematic Sampling Convenience Sampling
Identify which of these types of sampling is used random stratified systematic cluster convenience A market researcher selects 500 drivers under 30 years of age and 500 drivers over 30 years of?
This would be stratified; the two strata are ages of drivers < 30 & ages of drivers drivers >30.
What is a cluster gaps and outliers of a line plot?
A cluster is a group of data, or a bunch. A gap is a huge interval. An outlier is a piece of data that is really small or really big.
How is a transgression defined in mathematics?
A transgression in mathematics mean that there is a relation between elements of the n-th in a cluster of the fibre, and the n+1th cluster of the base of a fibre space.
What is a data cluster in math?
one big group of information

Why do shops cluster together?
Shops cluster together for the convenience of shoppers.
Breifly explain three different examples of sampling?
simple random, stratified sampling, cluster sampling
Which sampling is obtained by dividing the population into groups and selecting all individuals from within a random sample of the groups?
It is called one-stage cluster sampling. If random samples are taken within the selected clusters then it is two-stage cluster sampling.
Which sampling method is based on probability?
There are many such methods: cluster sampling, stratified random sampling, simple random sampling.Their usefulness depends on the circumstances.
Why is quota sampling different from other samplings?
Both being sub-parts of probability sampling, Random sampling differs in the sense as the sample is chosen out of a whole population randomly. whereas cluster sampling is extracted from a population already been selected by the same organization. eg. out of a whole population an area is selected by the management, which is the cluster, and is handed over to you to perform the tests necessary. Stratified sampling on the other hand is extracted according to the the categories the selected sample belongs to. These sectors selected might be on the basis of their nature of work, dealings etc. eg. industrial, commercial, residential and so on.
What is the difference between stratified random sampling and cluster sampling?
Basically in a stratified sampling procedure, the population is first partitioned into disjoint classes (the strata) which together are exhaustive. Thus each population element should be within one and only one stratum. Then a simple random sample is taken from each stratum, the sampling effort may either be a proportional allocation (each simple random sample would contain an amount of variates from a stratum which is proportional to the size of that stratum) or according to optimal allocation, where the target is to have a final sample with the minimum variabilty possible. The main difference between stratified and cluster sampling is that in stratified sampling all the strata need to be sampled. In cluster sampling one proceeds by first selecting a number of clusters at random and then sampling each cluster or conduct a census of each cluster. But usually not all clusters would be included.

What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
Define the four different sampling techniques?
1) Simple random sampling 2) Systematic sampling 3) Stratified sampling 4) Cluster sampling 5) Probability proportional to size sampling 6) Matched random sampling 7) Quota sampling 8) Convenience sampling 9) Line-intercept sampling 10) Panel sampling
What career cluster is for barbers?
Barbers typically fall under the career cluster of Human Services. This cluster includes professions that involve working directly with individuals to address their needs, concerns, or well-being.
