What sampling techniques does not need sampling frame?
Non-probability sampling techniques do not require a sampling frame. Examples include convenience sampling, where subjects are selected based on availability, and purposive sampling, where participants are chosen based on specific characteristics or criteria relevant to the research. These methods rely on the researcher's judgment rather than a complete list of the population. However, they may introduce bias and limit the generalizability of the findings.
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 2 types of biased sampling methods?
The two types of biased sampling methods are convenience sampling and judgmental sampling. Convenience sampling involves selecting individuals who are easiest to reach, which can lead to unrepresentative samples, while judgmental sampling relies on the researcher’s subjective judgment to choose participants, potentially introducing bias based on personal beliefs or preferences. Both methods can compromise the validity of the results by not accurately reflecting the larger population.
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and 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 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.
What are the important sampling methods Explain briefly?
Important sampling methods include simple random sampling, stratified sampling, systematic sampling, and cluster sampling. Simple random sampling ensures every member of the population has an equal chance of selection, while stratified sampling divides the population into subgroups and samples from each to ensure representation. Systematic sampling involves selecting every nth member from a list, and cluster sampling involves dividing the population into clusters and randomly selecting entire clusters for study. Each method has its advantages and is chosen based on the research objectives and population characteristics.
What are the sampling procedure in research methodology?
Sampling procedures in research methodology refer to the techniques used to select individuals or units from a larger population to gather data. Common sampling methods include random sampling, where each member has an equal chance of being selected; stratified sampling, which involves dividing the population into subgroups and sampling from each; and convenience sampling, where participants are chosen based on availability. The choice of sampling procedure impacts the representativeness of the sample and, consequently, the validity of the research findings. Proper sampling is crucial for reducing bias and enhancing the reliability of the study.
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.
