There are quite a number of sampling methods that can be employed in research and these include simple random sampling‚ systematic sampling‚ stratified sampling

What is Research? People undertake research in order to find things out in a systematic way‚ thereby increasing their knowledge (Jankowicz‚ 1995). “Systematic” suggests that research is based on logical relationships and not just beliefs (Ghauri and Gronhaug‚ 2010). To “find things out” suggests there are a multiplicity of possible purposes for your research (Becker‚ 1998). It is therefore an activity which has to be finished at some point to be of use. The results of research really are all around

In statistics‚ a simple random sample from a population is a sample chosen randomly‚ so that each possible sample has the same probability of being chosen. One consequence is that each member of the population has the same probability of being chosen as any other. In small populations such sampling is typically done "without replacement"‚ i.e.‚ one deliberately avoids choosing any member of the population more than once. Although simple random sampling can be conducted with replacement instead‚ this

If your answer to these questions is ’yes’‚ then you will need a hypothesis‚ but if it is ’no’ then you will need a research question. This is because a hypothesis is a statement that is tested by experiment(s) to confirm or deny the phenomenon Turning now to a research question‚ if you are incorporating

Related Literature ( Student - Athlete) Athletics have come to play a major role in the life of high schools and universities across the U.S. today (Griffith‚ 2004; Hamilton‚ 2005; Knox‚ 2007; Mock‚ 2003; Tublitz‚ 2007). Students who are involved in high school athletics tend to have higher academic achievement and better earnings later in life (see for example Broh‚ 2002; Guest & Schneider‚ 2003; Lipscomb‚ 2006; Marsh‚ 1992; and McNeal‚ 1995). High school students that participate in sports have

Ans.1: Non-Probability Sampling: When the units of a sample are chosen so that each unit in the population does not have a calculable non-zero probability of being selected in the sample‚ this is called Non-Probability Sampling. Also‚ Non-probability sampling is a sampling technique where the samples are gathered in a process that does not give all the individuals in the population equal chances of being selected. In contrast with probability sampling‚ non-probability sample is not a product
