7 Απρ 2020 · This calculator finds the probability of obtaining a certain value for a sample mean, based on a population mean, population standard deviation, and sample size. Simply enter the appropriate values for a given distribution below and then click the “Calculate” button.
Use this tool to calculate the standard deviation of the sample mean, given the population standard deviation and the sample size.
Since the sample mean follows a normal distribution, calculating probabilities for $\bar{x}$ simply involves converting to the standard normal distribution. The formula for converting from normal to standard normal involves subtracting by the mean and dividing by the standard deviation: $z=\frac{x-\mu}{\sigma}$.
Use this calculator to find the probability distribution of a sample statistic. This mean of sampling distribution calculator also calculates the characteristics of sample distribution such as expected value and standard error of a mean along with the graphical representation. What is Sampling Distribution?
Sample Mean Calculator. Data: Digits: Calculate. Clear. Load last run. Enter comma , space or Enter after each data value. The tool doesn't count empty cells or non-numeric cells. What is the sample mean? The sample mean is the average of the sample data that represents the middle of a set of numbers.
Our sample distribution calculator determines the sample mean, through related parameters like a population mean, standard deviation, and sample size. It derives the probability distribution of sample statistics that lie within a specified range. What is Sampling Distribution?
