sampling is a waste of time
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.
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
Sampling and Non sampling errors
Sampling has several disadvantages. These include time consuming and tedious. Possibly, members of units are different from one another, thus decreasing its effectiveness.
Advantages of Sampling:; Sampling has some advantages over the complete count. These are: ... Sometimes there is a need for sampling. Suppose we want to inspect the eggs, the bullets, the missiles and the tires of some firm.
definition of time sampling
sampling is a waste of time
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.
Advantages and Limitation of Sampling: 1. Sampling saves time and labour. 2. It results in reduction of cost in terms of money and manhour. 3. Sampling ends up with greater accuracy of results. 4. It has greater scope. 5. It has greater adaptability. 6. If the population is too large, or hypothetical or destroyable sampling is the only method to be used. The limitations of sampling are given below: 1. Sampling is to be done by qualified and experienced persons. Otherwise, the information will be unbelievable. 2. Sample method may give the extreme values sometimes instead of the mixed values. 3. There is the possibility of sampling errors.
Simple, it saves time and resources that could be directed at another hypothesis.
When carrying out a multi-site corporation employee survey, stratified sampling will give good results. Subsets of the employees, called strata, are used to save time and resources.
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming

Sampling Discritizes in time Quantization discritizes in amplitude
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...
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..
