In statistics, information is often inferred about a population by studying a finite number of individuals from that population, i.e. % What proportion of exam scores are between 82 82 and 89.2 89.2 points? You can also copy and paste lines of data from spreadsheets or text documents. Get started with our course today. The confidence interval depends on the sample size, n (the variance of the sample distribution is inversely proportional to n, meaning that the estimate gets closer to the true proportion as n increases); thus, an acceptable error rate in the estimate can also be set, called the margin of error, , and solved for the sample size required for the chosen confidence interval to be smaller than e; a calculation known as "sample size calculation.". For an explanation of why the sample estimate is normally distributed, study the Central Limit Theorem. Values must be numeric and may be separated by commas, spaces or new-line.

However, sampling statistics can be used to calculate what are called confidence intervals, which are an indication of how close the estimate p is to the true value p. The uncertainty in a given random sample (namely that is expected that the proportion estimate, p, is a good, but not perfect, approximation for the true proportion p) can be summarized by saying that the estimate p is normally distributed with mean p and variance p(1-p)/n. the commitment trust theory of relationship marketing pdf; Lavetta Cribbs Increasing the difference between hypothesis and true mean will.
