A sample frame is the list of people from which a sample for the study are selected. It is only carried out on the target population that the researcher is interested in studying. For example finding data on just school children would not involve the the whole population only children in schools.

What is the difference between sampling frame and sampling uinit?
Samplig frame is the source material from which the sample is drawn. If you have a 'list' of names of all inviduals from which you could draw a sample, the list is a sampling frame. A samplig unit is the sample being chosen.
What is the difference between Sampling error and non sampling error?
In stats, a sampling error is simply one that comes from looking at a sample of the population in question and not the entire population. That is where the name comes from. But there are other kinds of stats errors. In contrast, non sampling error refers to ANY other kind of error that does NOT come from looking at the sample instead of the population. One example you may want to know about of a non sampling error is a systematic error. OR Sampling Error: There may be inaccuracy in the information collected during the sample survey, this inaccuracy may be termed as Sampling error. Sampling error = Frame error + Chance error + Response error.
What sampling method does not require a frame?
Systematic sampling doesn't require a frame. This method takes in every data from a sample, rather than restricting it by any particular means.
What are the advantages and disadvantages of mixed sampling?
avantages and disadvantages of mixed sampling are explained by example given below : if we want to take sample of trees in the forest of India for this we will selected the forests by the simple random sampling and after this we will selected the trees by the systematic sampling we can not used simple random sampling here due to not availability of frame of trees.So this is adavantages of mixed sampling. Now if we want to check the relability of whole procedure then we will not check it .So this is disadavantages of mixed sampling.
Why is a frame necessary to obtain a simple random sample?
because it is the list that is used for assigning numbers to individual in the population.

Define sampling design?
Sampling is a method of selecting experimental units from a population so that we can make decision about the population. Sampling design is a design, or a working plan, that specifies the population frame,sample size, sample selection, and estimation method in detail. Objective of the sampling design is to know the characteristic of the population.
What is a sample frame?
A list of all eligable sampling units from which the sample can be drawn (eg telephone directories, electronic registers, company lists, club membership lists etc)
What is Sampling frame?
A sampling frame is defined as the complete list or a map that contains all the "n" sampling units in a population
What is the difference between Taurus firearm 66 frame and 606 frame?
a 540 difference

What is bias sample?
Sampling bias occurs when the sampling frame does not reflect the characteristics of the population which is being tested. Biased samples can result from problems with either the sampling technique or the data-collection method. Essentially, the group does not reflect the population which is supposed to be represented in the given survey or test. For example: If the question being asked in a survey was "do American's prefer Coca-Cola or Pepsi?" and all people asked were under 18 and from California, there would be a sampling bias as the sampling frame would not accurately represent "American's".
What is the difference between chassis and frame?
A frame is the skeleton of a car without the mountings, were as a chasis is a mounted frame.
What is the definition of a systematic type of sampling in biology?
As the wikipedia article on this subject suggests, systematic sampling is most readily applied when potential sample elements are linearly ordered either in time or space. For example, one could choose to include every fifth customer arriving at a store in one's sample, which would be an instance where sample elements are ordered in time. The difficulty with many research situations in biology is obviously that sample elements are not linearly ordered. A herd of buffalo in a grassy field, for example, or a collection of microorganisms on a microscope slide. Remedies depend on circumstances. Suppose you want to apply systematic sampling in a small forest where you want to estimate the fraction of trees infested with a certain species of insect. You decide on, say, a one in five sample and that you will include 500 trees in your sampling frame in order to get a sample size of 100. To begin you walk enough parallel transects through the forest, marking sufficiently large trees as you go, to get your 500-tree sampling frame. Then you take a second trip through along transects to identify infested trees.
How do you explain the meaning and purpose of a sampling frame in random sampling?
The term "sampling frame" may have no meaning at all in "random" sampling, since the "frame" by nature sets the parameters of the sampling, thus rendering the sampling somewhat "non-random". Having said that, you might want to study the quality of corn in your area and, depending on which aspects or determining factors you are studying, you might set your sampling frame as "all the farmers in Waterloo region" or "all the farmers in a particular area growing Gold Harvest F1 Hybrid". These two examples will obviously give you different results as they are intended to study different aspects of corn.
