I am very happy with the service. It is easy to use and very versatile. It is, however, quite expensive for the annual plan. Even if I used this on a daily basis, I'd feel like50 a year is much more reasonable.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Answer: To find a 95% CI with a margin of error no more than ±3.5 percentage points, where the true population proportion is around 42%, you must survey at least 764 people. 10Ã764 = 7640. Presumably the electorate is larger than that.
How do you find the confidence level of a sample size?
ZA/2: Divide the confidence interval by two, and look that area up in the z-table: .95 / 2 = 0.475. E (margin of error): Divide the given width by 2. 6% / 2. use the given percentage. 41% = 0.41. subtract. From 1.
How do you know if a sample size is large enough?
You have a symmetric distribution or unimodal distribution without outliers: a sample size of 15 is large enough. You have a moderately skewed distribution, that's unimodal without outliers. If your sample size is between 16 and 40, it's large enough. Your sample size is >40, as long as you do not have outliers.
How do you determine a good random sample size?
Specify the desired margin of error ME. This is your measure of precision. Specify alpha. Find the critical standard score z. Unless the population size is very large relative to sample size (e.g., 20 times larger), you need to specify the size of the population (N).
How big of a sample size do I need to be statistically significant?
Generally, the rule of thumb is that the larger the sample size, the more statistically significant it is meaning there's less of a chance that your results happened by coincidence.
What is the formula for determining sample size?
Sample Size Calculation: Sample Size = (Distribution of 50%) / ((Margin of Error / Confidence Level Score)Squared) Finite Population Correction: True Sample = (Sample Size X Population) / (Sample Size + Population 1)
What is the formula for calculating sample size?
Sample Size Calculation: Sample Size = (Distribution of 50%) / ((Margin of Error / Confidence Level Score)Squared) Finite Population Correction: True Sample = (Sample Size X Population) / (Sample Size + Population 1)
How do you determine a sample size from a population?
Population size: The total number of people in the group you are trying to study. If you were taking a random sample of people across the U.S., then your population size would be about 317 million. Similarly, if you are surveying your company, the size of the population is the total number of employees.
