For example the percentage may be 50% I have a sample size of 16 and using a stat http://www.excelbanter.com/showthread.php?t=286163 testing program (STATCHCK) I know the margin of error is +/- 25% so my maximum would be 75% and my minimum would be 25%. My problem is I have over 10,000 numbers to check and I want to automate this in excel. I know there is a data analysis add in excel but not sure if it can be used to solve my problem. Any help with my problem would be greatly appreciated. If you think this should be posted somewhere else please let me know.

to Compute the Margin of Error Margin of Error Calculator Enter the sample size n. Enter a value between 0 and 1 for p, or if p is unknown, use p = 0.5. Enter the population size http://www.had2know.com/business/compute-margin-of-error.html N, or leave blank if the total population is large. npN https://blog.udemy.com/confidence-interval-excel/ In statistics, the margin of error represents the approximate amount of variance you can expect in polls and surveys. For example, suppose you conduct a poll that indicates 40% of people will vote 'no' on a proposition, and the margin of error is 3%. This means that if you were to margin of conduct the same poll with another random sample of similar size, you could expect 37%-43% of the respondents in the second survey to also vote 'no.' The margin of error tells you how accurate poll results are; the smaller the margin of error, the greater the accuracy. There are two main formulas for calculating the margin of error, each explained below. In each formula, the sample margin of error size is denoted by n, the proportion of people responding a certain way is p, and the size of the total population is N. For some margin of error formulas, you do not need to know the value of N. 95% Confidence Interval Margin of Error If you have a sample that is drawn from a very large population (N is larger than 1,000,000), then you can compute the "95% confidence interval margin of error" with the formula MOE = (1.96)sqrt[p(1-p)/n]. If you perform 100 surveys with the same sample size drawn from the same poplulation, then 95% of the time you can expect the margin of error to fall within the bound above. As you can see, N does not factor into this equation for margin of error. If the total population is large enough, only the size of the random sample matters, not the total population. If the survey has multiple questions and there are several possible values for p, pick the value that is closest to 0.5. Here is an example: In a random survey of 1,000 Texans, 48% of the respondents liked chocolate ice cream more than vanilla, 46% liked vanilla
2014 by Arpita Bhattacharjee Advanced Excel Functions offer excellent and convenient methods for different statistical calculations and analysis and are of great benefit to statisticians. One such feature is the Confidence Interval which statisticians use to express the degree of uncertainty associated with a sample. Confidence Interval is an interval estimate combined with a probability statement. The Udemy course Confidence Intervals and Sample Sizes Estimations vividly describes the different functions of confidence interval. It explains the concepts of confidence intervals and how to determine sample sizes, how to interpret confidence intervals, how to calculate confidence intervals about the population mean, population proportion, population variance, and population standard deviation. What is Confidence Interval? In any survey and user research, confidence intervals are an excellent way of understanding the role of sampling errors in averages and percentages. For any survey, as we almost always sample a fraction of the users from a larger population, there is always uncertainty in our estimates. There will always be sample errors due to sampling. Confidence interval gives an idea about how much the average value is likely to fluctuate. Significance of Confidence Interval The confidence interval is a range of values that are centered equally from a known sample mean. The higher your confidence level (percentage) the smaller your interval will be and therefore the more accurate your results will be. Population of samples with more variability or greater standard deviation generates wider confidence intervals. There is also an inverse square root relationship between confidence intervals and sample sizes. Smaller sample sizes generate wider intervals and so for better estimates or to cut your margin of error by half, you need to approximately quadruple your sample size. How to Construct Confidence Interval? To construct the confidence interval for a population mean, for a supplied probability and sample size, we need to use the CONFIDENCE function in Excel which uses a Normal Distribution to calculate the confidence value that can be used. Suppose we randomly selected 100 people, measured their weight, and computed their average weight as 155 Pounds. If we now want to know the average weight of the entire population in that particular city, it is highly unlikely that the average for this bigger population will have the same average as our sample of just 100 people. It
