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.
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 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.
What is a data cluster in math?
one big group of information

What are sutiable sampling techniques other than stratified sampling?
Suitable sampling techniques other than stratified sampling include simple random sampling, where each member of the population has an equal chance of being selected; systematic sampling, which involves selecting every nth individual from a list; and cluster sampling, where the population is divided into clusters, and entire clusters are randomly selected. Convenience sampling, though less rigorous, involves selecting individuals who are easily accessible. Each method has its own advantages and limitations, depending on the research goals and population characteristics.

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.
How many types of random sampling?
There are several types of random sampling, with the most common being simple random sampling, stratified sampling, cluster sampling, and systematic sampling. Simple random sampling gives each member of the population an equal chance of being selected. Stratified sampling involves dividing the population into subgroups and sampling from each subgroup. Cluster sampling selects entire groups or clusters, while systematic sampling involves selecting members at regular intervals from a randomly ordered list.
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.

They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
