**Is it meaningful to calculate standard deviation of two**

Estimating Standard Deviation. Q: I need an estimate of the standard deviation of the weights of a production lot of large and bulky parts, but I don't have time or facilities to measure a bunch of parts.... To calculate control limits for each SPC chart requires we estimate the standard deviation. This estimate of the standard deviation depends on the sampling program. Click on This estimate of the standard deviation depends on the sampling program.

**Is it meaningful to calculate standard deviation of two**

At 4:30 of this video the author decided to estimate the standard deviation of the population with sample standard deviation (sample size was $100$). In the next video, the author mentioned that it was reasonable because the sample size greater than $30$.... How do I get the sample size used if I know the (standard deviation 15), A 95% confidence interval for a population mean was reported to be 152 to 160. 0 May 31, 2018 at 10:52 am - Log in to Reply

**Calculating standard deviation from a confidence interval**

If you can get up to 3 data points, the multiplicative factor on the sample standard deviation to get a two-sided confidence interval goes down from 12.71 to 4.30. That's a 66% savings. And if you act in the next 15 minutes, I'll give you some additional "savings" in the form of n-1 vs. n not dinging you as badly in the denominator of the formula for sample standard deviation when n = 3 vs. 2. how to find your g spot To calculate control limits for each SPC chart requires we estimate the standard deviation. This estimate of the standard deviation depends on the sampling program. Click on This estimate of the standard deviation depends on the sampling program.

- Use the standard deviation of the population parameter given in the problem or estimate the standard deviation. If it is not given, use the standard deviation from a similar study. If neither is available, roughly estimate a standard deviation such that it will be approximately 34 percent of the population.

- As such, the "corrected sample standard deviation" is the most commonly used estimator for population standard deviation, and is generally referred to as simply the "sample standard deviation." It is a much better estimate than its uncorrected version, but still has significant bias for small sample sizes (N 10).
- At 4:30 of this video the author decided to estimate the standard deviation of the population with sample standard deviation (sample size was $100$). In the next video, the author mentioned that it was reasonable because the sample size greater than $30$.
