True Error given Relative Error Solution

STEP 0: Pre-Calculation Summary

Formula Used

True Error = Relative Error*Observed Value
ε_x = R_x*x
This formula uses 3 Variables

Variables Used

True Error - True error is the difference between the true value of a quantity and its observed value.
Relative Error - Relative error is a measure of the error in relation to the size of the measurement.
Observed Value - Observed value is the value which the observer notes during surveying.

STEP 1: Convert Input(s) to Base Unit

Relative Error: 2 --> No Conversion Required
Observed Value: 159 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ε_x = R_x*x --> 2*159

Evaluating ... ...

ε_x = 318

STEP 3: Convert Result to Output's Unit

318 --> No Conversion Required

FINAL ANSWER

318 <-- True Error

Standard Error of Function where variables are Subjected to Addition

Go Standard Error in Function = sqrt(Standard Error in x coordinate^2+Standard Error in y coordinate^2+Standard Error in z coordinate^2)

Most Probable Value with Different Weightage

Go Most Probable Value = add(Weightage*Measured Quantity)/add(Weightage)

Standard Deviation of Weighted Observations

Go Weighted Standard Deviation = sqrt(Sum of Weighted Residual Variation/(Number of Observations-1))

Standard Deviation used for Survey Errors

Go Standard Deviation = sqrt(Sum of Square of Residual Variation/(Number of Observations-1))

Mean Error given Specified Error of Single Measurement

Go Error of Mean = Specified Error of a Single Measurement/(sqrt(Number of Observations))

Standard Error of Mean of Weighted Observations

Go Standard Error of Mean = Weighted Standard Deviation/sqrt(Sum of Weightage)

Probable Error of Mean

Go Probable Mean of Error = Probable Error in Single Measurement/(Number of Observations^0.5)

Variance of Observations

Go Variance = Sum of Square of Residual Variation/(Number of Observations-1)

Mean Error given Sum of Errors

Go Error of Mean = Sum of Errors of Observations/Number of Observations

Most Probable Value with Same Weightage for Observations

Go Most Probable Value = Sum of Observed Values/Number of Observations

Residual Variation given Most Probable Value

Go Residual Variation = Measured Value-Most Probable Value

Most Probable Value given Residual Error

Go Most Probable Value = Observed Value-Residual Error

Observed Value given Residual Error

Go Observed Value = Residual Error+Most Probable Value

Residual Error

Go Residual Error = Observed Value-Most Probable Value

Observed Value given Relative Error

Go Observed Value = True Error/Relative Error

True Error given Relative Error

Go True Error = Relative Error*Observed Value

Relative Error

Go Relative Error = True Error/Observed Value

Observed Value given True Error

Go Observed Value = True Value-True Error

True Value given True Error

Go True Value = True Error+Observed Value

True Error

Go True Error = True Value-Observed Value

Most Probable Error given Standard Deviation

Go Most Probable Error = 0.6745*Standard Deviation

True Error given Relative Error Formula

True Error = Relative Error*Observed Value
ε_x = R_x*x

What is an Indirect Observation?

An indirect observation is one in which the observed value is deduced from the measurement of some related quantities, e.g., the measurement of angle by repetition (a multiple of the angle being measured.)

How to Calculate True Error given Relative Error?

True Error given Relative Error calculator uses True Error = Relative Error*Observed Value to calculate the True Error, The True Error given Relative Error relates the relationship between the relative error and observed value. True Error is denoted by ε_x symbol.
