What is the definition of nonprobability sampling?
Non-probability sampling is a type of sampling technique whereby all the units of a population do not have an equal chance of being selected in the sample.it may further be divided intoConvenience: Sampling units are selected as per convenience of the researcherPurposive: The units selected in a sample are selected because they posses some requires characteristic e.g., clinical knowledge etc
What is synoptic sampling?
Synoptic sampling is the collection of samples from many locations during a short period of time, typically a few hours.
What is the definition of 'at that time'?
"at that time" = "then"
Definition of a?
The definition of a is used when referring to someone or something for the first time in a text or conversation.
What is the definition of disorientated?
confused about time or place
What kind of errors arise in sampling?
sampling is a waste of time
Definition of sampling method in research methodology?
sampling is a process of getting information about a population by asking questions from a potion of people who belong with that population
Is it sampling time and sampling interval same?
Nope. Sampling time - is the amount of time it takes to obtain the sample. Sampling interval - is the period of time between samples. For example - it may take 10 seconds to obtain a sample. Obtaining a sample once a day is a sampling interval of 24 hours.
How would you define the sampling universe and why you chose this sample definition?
The sampling universe is the totatility of items/events from which you can select or sample for statistical analysis and description.
Advantages and disadvantages of simple random sampling?
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
What is the instantaneous sampling?
Instantaneous sampling is one method used for sampling a continuous time signal into discrete time signal. This method is called as ideal or impulse sampling. In this method, we multiply a impulse function with the continuous time signal to be sampled. The output is instantaneously sampled signal.
What is the Different between sampling and quantization?
Sampling Discritizes in time Quantization discritizes in amplitude
When to apply sampling?
you can use sampling when your population under study is large, expensive and time time consuming to study.... in a nut shell, when studying entire population is expensive we go for sampling...
What is sampling and holding time?
sampling time is the number of samples per second taken from a continuous signal to make it discrete and holding time is the time between two samples..
What is the definition of a systematic type of sampling?
Systematic sampling occurs when you have a list of people, then you select every 10th person on the list. No bias will occur as long as the order of the people on the list is not important.
How does the sampling oscilloscope increase the appearent frequency response of an osciloscope?
A: A sampling scope is not real time scope but rather a hi frequency rate of sampling which benefit the observer
What are the reasons for choosing random sampling method for ones research work and what is random sampling method anyway?
because it is the simplest sampling technique which requires less time and cost.
