A point estimation is a sample statistic that gives a good guess about a population parameter. In the same way‚ a point estimate of the mean overpayment is simply a good guess about what the average overpayment for the population is. Investigating all 1‚000 claims and obtaining the overpayment amount for each would either be impractical‚ unfeasible or both. Thus‚ the auditor deems a sample size of 50 claims to be adequate and sufficiently representative of the entire population. The mean overpayment

is usually done as products leave the factory‚ or in some cases even within the factory. Most often a producer supplies a consumer a number of items and decision to accept or reject the lot is made by determining the number of defective items in a sample from the lot. The lot is accepted if the number of defects falls below where the acceptance number or otherwise the lot is rejected.[1] A wide variety of acceptance sampling plans are available.

companies will show a common factor in safety incidents leading to catastrophic events. Sample Design A non-probability sample design will be used for collecting data. However‚ to select effectively a sample design certain questions must be answered. They include‚ “What is the target population? What are the parameters of interest? What is the sampling frame? What is the appropriate sampling method? What size sample is needed” (Cooper & Schindler‚ 2011‚

this may not be true. Even the slightest element of bias in such an inquiry will get larger and larger as the number of observation increases. Moreover‚ there is no way of checking the element of bias or its extent except through a resurvey or use of sample checks. Besides‚ this type of inquiry involves a great deal of time‚ money and energy. Therefore‚ when the field of inquiry is large‚ this method becomes difficult to adopt because of the resources involved. At times‚ this method is practically beyond

Concept and basics of probability sampling methods One of the most important issues in researches is selecting an appropriate sample. Among sampling methods‚ probability sample are of much importance since most statistical tests fit on to this type of sampling method. Representativeness and generalize-ability will be achieved well with probable samples from a population‚ although the matter of low feasibility of a probable sampling method or high cost‚ don’t allow us to use it and shift us to the

the researcher divides the entire population into different subgroups or strata‚ then randomly selects the final subjects proportionally from the different strata” (Sincero‚ 2012). In surveys‚ the sampling frame is the list of cases from which the sample is selected. Easily obtained sampling frames would include telephone directories and lists of electors. These have obvious problems in terms of non-representativeness -for example‚ telephone directories only list people with telephones who are responsible
