# Standard Error Of A Single Proportion

0 otherwise. The standard deviation of any variable involves the confidence interval of proportion expression . Let's suppose there are m 1s (and n-m 0s) among the n subjects. Then, and is equal to (1-m/n) for m observations and 0-m/n

for (n-m) observations. When these results are combined, the final result is and the sample variance (square of the SD) of the 0/1 observations is The sample proportion is the mean of n of these observations, so the standard error of the proportion is calculated like the standard error of the mean, that is, the SD of one of them divided by the square root of the sample size or Copyright © 1998 Gerard E.

Estimation Requirements The approach described in this lesson is valid whenever the following conditions are met: The sampling method is simple random sampling. The standard error sample is sufficiently large. As a rule of thumb, a sample is considered "sufficiently large" if it includes at least 10 successes and 10 failures. Note the implications of the second condition. If the population proportion were close to 0.5, the sample size required to produce at least 10 successes and at least 10 failures would probably be close to 20. But if the population proportion were extreme (i.e., close to 0 or standard error of 1), a much larger sample would probably be needed to produce at least 10 successes and 10 failures. For example, imagine that the probability of success were 0.1, and the sample were selected using simple random sampling. In this situation, a sample size close to 100 might be needed to get 10 successes. The Variability of the Sample Proportion To construct a confidence interval for a sample proportion, we need to know the variability of the sample proportion. This means we need to know how to compute the standard deviation and/or the standard error of the sampling distribution. Suppose k possible samples of size n can be selected from the population. The standard deviation of the sampling distribution is the "average" deviation between the k sample proportions and the true population proportion, P. The standard deviation of the sample proportion σp is: σp = sqrt[ P * ( 1 - P ) / n ] * sqrt[ ( N - n ) / ( N - 1 ) ] where P is the population proportion, n is the sample size, and N is the population size. When the population size is much larger (at least 20 times larger) than the sample size, the standard deviation can be approximated by: σp = sqrt[ P * ( 1 -

relationship between two or more categorical variables. Note: This section addresses the first two areas -- see the chi-square test for a discussion of the latter. Confidence Intervals and Significance Tests for a Single Proportion Given a simple random sample of size n from a population, the number of "successes" X divided by the sample size n provides the sample proportion , an estimate of the population proportion p. This proportion follows a binomial distribution with mean p and variance (p(1-p))/n. Since the binomial distribution is approximately normal for large sample sizes, tests of significance and confidence intervals for a single proportion use a z statistic. Example A marketing team wishes to evaluate the popularity of a new product in a particular city. A random survey of 500 shoppers indicates that 287 shoppers favor the new product, 123 shoppers dislike the product, and the remaining 90 shoppers have no opinion. Is there evidence that more than 50% of shoppers like the product? The sample proportion of shoppers who favor the product is 287/500 = 0.574. What is a 95% confidence interval for the proportion? Is the proportion significantly different from 0.5? To find a confidence interval for a proportion, estimate the standard deviation sp from the data by replacing the unknown value p with the sample proportion , giving the standard error sp = . An approximate level C confidence interval for p is + z* where z* is the upper (1-C)/2 critical value from the standard normal distribution. Example In the example above, the sample proportion is 0.574. The standard error sp is equal to sqrt((0.574(1-0.574))/500) = sqrt((0.574*0.426)/500) = sqrt(0.245/500) = sqrt(0.00049) = 0.022. The critical value for a 95% confidence interval is 1.96, so the confidence interval for the proportion is 0.574 + 1.96*0.022 = (0.574 - 0.043, 0.574 + 0.043) = (0.531, 0.617). To test the null hypothesis H0: p = p0 against a one- or two-sided alternative hypothesis Ha, replace p with p0 in the test statis
