Breifly explain three different examples of sampling?
simple random, stratified sampling, cluster sampling
What is systematic sampling use for?
In practice, systematic sampling is used on account of its simplicity and convenience. It's easy to explain to the people doing the actual work. It can be justified theoretically wherever the population from which units are to be sampled systematically are randomly distributed. It can be used for sampling households, sampling callers on a telephone line, sampling plants along a transect in (say) a field, sampling people passing through customs, and so on.
How do you explain sampling techniques in research with reference to quantitative techniques?
sampling techniques? okey, here's what to do... step 1go to google then type whatver you want to rsearch on. step2 read what has come up on wiki answers then i dont know
What is meant by the term logistic regression?
The term "Logistic regression" is referring to the graph of analysis in predictions. There are variables involved and explain probabilities that are a hypothesis of the dependent variable, which is the one being applied to a future prediction.
Explain how a person taking a survey to find the percent of sport fans who chose baseball as their favorite sport might get a biased sample?
Conduct your sampling at a baseball game, a baseball museum or at a meeting of Little League coaches.

Explain the importance of random and stratified sampling?
A sampling method in which all members of a group have an equal and independent chance of being selected.

Explain the need to use sampling techniques to make population estimates when total counts cannot be made?
Sometimes a definite count of individuals within a population is not possible, the population may be constantly moving or distributed over a large area. In such cases, an estimate is made by counting small samples.
How is the validity of theory tested?
-- Does it explain things that have already been observed ?-- Does it make predictions that can be tested, and when tested, are found to be true ?

Explain why cash flow forecasts may be inaccurate?
they are only based on estimates, so they are really unpredictable, especially if the business is new and has no past data to base the estimates on.
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.
We have a population with mean of 100 and standard deviation of 28 take repeated samples of size 49 and calculate the mean of each sample to form a sampling distribution Is it a Normal Distribution?
a) T or F The sampling distribution will be normal. Explain your answer. b) Find the mean and standard deviation of the sampling distribution. c) We pick one of our samples from the sampling distribution what is the probability that this sample has a mean that is greater than 109 ? Is this a usual or unusual event? these are the rest of the question.

What is the nature of hypothesis testing?
A hypothesis must be subjected to rigorous testing before it becomes a theory. A hypothesis is used to explain some phenomenon about the natural world. Once a hypothesis has been created, it can be used to formulate predictions. These predictions in turn are then tested to be accurate through experimentation or observation.
