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?
Standard error calculator uses Residual standard error = Standard Deviation/sqrt(Number of Samples) to calculate the Residual standard error, The Standard error formula is defined as the mathematical tool used in statistics to measure variability. It enables one to arrive at an estimation of what the standard deviation of a given sample is. Residual standard error is denoted by RSE symbol.
How to calculate Standard error using this online calculator? To use this online calculator for Standard error, enter Standard Deviation (σ) & Number of Samples (N_{s}) and hit the calculate button. Here is how the Standard error calculation can be explained with given input values -> 0.665 = 1.33/sqrt(4).
