ANSWER: Sampling is that part of statistical practice concerned with the selection of an unbiased or random subset of individual observations within a population of individuals intended to yield some knowledge about the population of concern‚ especially for making predictions based on the statistical inference (Ader‚ Mellenberg & Hand: 2008). There are quite a number of sampling methods that can be employed in research and these include simple random sampling‚ systematic sampling‚ stratified sampling

to the amount each item contributes to the profitability of the business‚ without Cost accounting. Before detailing about these methods there are 3 main elements of costs used within the methods‚ which are fixed‚ variable and semi variable costs. Fixed cost are costs that tend not to be affected by fluctuations in activity for example rent for the year of a premises‚ where as a variable cost varies in direct proportion to the level or volume of activity‚ so for instance the greater number of plastic

Types of Sampling In applications: Probability Sampling: Simple Random Sampling‚ Stratified Random Sampling‚ Multi-Stage Sampling * What is each and how is it done? * How do we decide which to use? * How do we analyze the results differently depending on the type of sampling? Non-probability Sampling: Why don’t we use non-probability sampling schemes? Two reasons: * We can’t use the mathematics of probability to analyze the results. * In general‚ we can’t count on a non-probability

Because there is seldom enough time or money to gather information from everyone or everything in a population‚ the goal is to find a representative sample (or subset) of that population. For example‚ a researcher might study the success rate of a new ’quit smoking’ program on a sample group of 50 patients‚ in order to predict the effects of the program if it were
