Is it correct to calculate the standard deviation using duplicate analysis?
No it is not correct.
What is a coded-deviation method in statistics?
Differing from standard deviations, the coded deviation method finds the mean of grouped data from the assumed mean using unit deviations. This is a shorter way to find the mean.
How do you calculate the parameter to a 99.9 confidence interval using mean and standard deviation?
Did you mean, "How do you calculate the 99.9 % confidence interval to a parameter using the mean and the standard deviation?" ? The parameter is the population mean μ. Let xbar and s denote the sample mean and the sample standard deviation. The formula for a 99.9% confidence limit for μ is xbar - 3.08 s / √n and xbar + 3.08 s / √n where xbar is the sample mean, n the sample size and s the sample standard deviation. 3.08 comes from a Normal probability table.
How do you find graph median by using standard deviation?
You cannot because the median of a distribution is not related to its standard deviation.
Which measure of variation is appropriate when using the mean?
The variance or standard deviation.
How do you calculate standard deviation using median?
You cannot because the standard deviation is not related to the median.
Is it correct to calculate the standard deviation using duplicate analysis?
No it is not correct.
How do you calculate the standard deviation of the mean using Excel?
=stdev(...) will return the N-1 weighted sample standard deviation. =stdevp(...) will return the N weighted population standard deviation.
What is the standard error of the sampling distribution equal to when you do not know the population standard deviation?
You calculate the standard error using the data.
How do you properly incorporate the calculation of standard deviation into a lab report?
To properly incorporate the calculation of standard deviation into a lab report, first calculate the standard deviation of your data set using the appropriate formula. Then, include the standard deviation value in the results section of your report, along with any relevant interpretations or implications. Additionally, consider discussing the significance of the standard deviation in relation to the overall findings of your experiment.

You cannot because the median of a distribution is not related to its standard deviation.
Can standard deviation be calculated for non normal data?
Standard deviation can be calculated using non-normal data, but isn't advised. You'll get abnormal results as the data isn't properly sorted, and the standard deviation will have a large window of accuracy.
Which measure of variation is appropriate when using the mean?
The variance or standard deviation.
What is standard deviation stretch?
The standard deviation stretch is used to stretch the output values using a normal distribution. The result of this stretch is similar to what is seen by the human eye.
Is a standard deviation of 18 considered high?
The standard deviation, in itself, cannot be high nor low. If the same measurements were recorded using a unit that was a ten times as large (centimetres instead of millimetres), the standard deviation for exactly the same data set would be 1.8. And if they were recorded in metres the sd would be 0.018
