What are the disadvantages of sampling?
You do not have all the information and so your conclusions are based on approximations.
Is sampling distribution more compact when is is based on smaller samples?
No: the opposite.
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
What are the sources of sampling errors?
Sampling and Non sampling errors
Types of sampling techniques?
It is a sampling method in which units are selected based on easy access/availability. The disadvantage of convenience sampling is that the units that are easiest to obtain may not be representative of the population. For example products on top of a box of parts may be a different quality from those at the bottom, people who are at home when the market researcher calls may not be representative of the entire population. It is also called as Accidental 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 scope frequency is always greater then signal frequency in the oscilloscope?
In the course of sampling a signal to graph the parts of a repeating event on the display, the sampling must be done faster than the event you want to graph. If the sampling is done slower than the event then you will be displaying several parts of the event in a single dot on the display, highly inaccurate. The signal sampling must be done fast enough to display the event in enough detail. The higher you set the scope frequency, the wider the event appears on the display, possibly losing the sides of the event if you go too high.
When every Member of a population has the chance of being selected based on probability what type of sampling is this?
Simple random sampling.
When every member of a population has the chance of being selected based on the probability or frequency of its representation in that population you are using which type of sampling?
Systematic sampling

Is sampling distribution more compact when is is based on smaller samples?
No: the opposite.
Which diagnostic test is based on a specimen that is obtained between the 8th and 10th weeks of pregnancy?
Chorionic Villus Sampling (CVS)
Sampling is a method of estimating population?
Sampling makes it possible to make assumptions about the larger population based on a small sample. This is beneficial in the study of population and demographics.
Is the film lion king based on a true event?
No it is not based on a true event.
How probability sampling is used?
Probability sampling is used to select a sample from a population in such a way that every individual or element in the population has a known and non-zero chance of being selected. This method ensures that the sample is representative of the population, allowing for generalizations and statistical inferences to be made with greater validity and accuracy. Probability sampling techniques include simple random sampling, stratified sampling, cluster sampling, and systematic sampling.
Difference between restricted and unrestricted sampling?
Difference between restricted sampling and unresticted sampling
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
