What is statistics?
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied.
How to Calculate Standard error of difference of sample mean?
Standard error of difference of sample mean calculator uses Standard Error = sqrt(((Standard Deviation^2)/Sample Size 1)+((Standard deviation 2^2)/Sample size 2)) to calculate the Standard Error, The Standard error of difference of sample mean formula is defined as statistical term that measures the accuracy with which a sample distribution represents a population by using standard deviation. In statistics, a sample mean deviates from the actual mean of a population; this deviation is the standard error of the mean. Standard Error is denoted by Error_{Standard} symbol.
How to calculate Standard error of difference of sample mean using this online calculator? To use this online calculator for Standard error of difference of sample mean, enter Standard Deviation (σ), Sample Size 1 (n1), Standard deviation 2 (SD2) & Sample size 2 (n2) and hit the calculate button. Here is how the Standard error of difference of sample mean calculation can be explained with given input values -> 0.827258 = sqrt(((1.33^2)/100)+((10^2)/150)).
