Difference between calculating the sample mean and the population mean?
The same basic formula is used to calculate the sample or population mean. The sample mean is x bar and the population mean is mu. Add all the values in the sample or population and divide by the number of data values.
If the formula is used to find the mean of the following sample what is the value of n 2 63 88 10 72 9?
n=6
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.
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.

If the formula is used to find the mean of the following sample what is the value of n 2 63 88 10 72 9?
n=6
Why is the sample standard deviation used to derive the standard error of the mean?
the sample mean is used to derive the significance level.
How much error between sample mean and population mean?
The answer depends on the underlying variance (standard deviation) in the population, the size of the sample and the procedure used to select the sample.
What is a numerical value used as a summary measure for a sample called such as a sample mean?
sampl statistics
A numerical value used as a summary measure for a sample such as sample mean is known as a?
This is called a sample statistic. They are often used to give a general picture of a more specific whole.
Are Greek letters used for statistics or for parameters?
Greek letters are used for population parameters. Eg: µ is the population mean English letters are used for sample statistics. Eg: x-bar is the sample mean
What happens to the sample mean as the sample size increases?
With a good sample, the sample mean gets closer to the population mean.

What is the difference between the population mean and sample mean?
The population mean is the mean calculated over every member of the set of subjects being studied. It is usually not available and a survey is used to find an estimate for the population mean. The mean value of the variable in question, calculated from only the subjects included in the sample (or survey) is the sample mean. Provided some basic statistical requirements are met, the sample mean is a "good" estimate of the population mean.
