Standard error Solution

STEP 0: Pre-Calculation Summary
Formula Used
Residual standard error = Standard Deviation/sqrt(Number of Samples)
RSE = σ/sqrt(Ns)
This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Residual standard error - Residual standard error is the estimate of variance from the data.
Standard Deviation - The Standard Deviation is a measure of how spread out numbers are.
Number of Samples - The Number of Samples of a continuous-time signal is the total samples in the output sample signal.
STEP 1: Convert Input(s) to Base Unit
Standard Deviation: 1.33 --> No Conversion Required
Number of Samples: 4 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
RSE = σ/sqrt(Ns) --> 1.33/sqrt(4)
Evaluating ... ...
RSE = 0.665
STEP 3: Convert Result to Output's Unit
0.665 --> No Conversion Required
FINAL ANSWER
0.665 <-- Residual standard error

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 (Ns) 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).

FAQ

What is 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 and is represented as RSE = σ/sqrt(Ns) or Residual standard error = Standard Deviation/sqrt(Number of Samples). The Standard Deviation is a measure of how spread out numbers are & The Number of Samples of a continuous-time signal is the total samples in the output sample signal.
How to calculate 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 is calculated using Residual standard error = Standard Deviation/sqrt(Number of Samples). To calculate Standard error, you need Standard Deviation (σ) & Number of Samples (Ns). With our tool, you need to enter the respective value for Standard Deviation & Number of Samples and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Residual standard error?
In this formula, Residual standard error uses Standard Deviation & Number of Samples. We can use 2 other way(s) to calculate the same, which is/are as follows -
  • Residual standard error = sqrt(Residual sum of squares/(Number of Observations in data-2))
  • Residual standard error = F statistic*Residual sum of squares/Total sum of squares
