Observed Value given True Error Solution

STEP 0: Pre-Calculation Summary
Formula Used
Observed Value = True Value-True Error
x = X-εx
This formula uses 3 Variables
Variables Used
Observed Value - Observed value is the value which the observer notes during surveying.
True Value - True value is the actual value of any process done in survey.
True Error - True error is the difference between the true value of a quantity and its observed value.
STEP 1: Convert Input(s) to Base Unit
True Value: 480 --> No Conversion Required
True Error: 320 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
x = X-εx --> 480-320
Evaluating ... ...
x = 160
STEP 3: Convert Result to Output's Unit
160 --> No Conversion Required
FINAL ANSWER
160 <-- Observed Value
(Calculation completed in 00.004 seconds)

Theory of Errors Calculators

Mean Error given Specified Error of Single Measurement
​ LaTeX ​ Go Error of Mean = Specified Error of a Single Measurement/(sqrt(Number of Observations))
Probable Error of Mean
​ LaTeX ​ Go Probable Mean of Error = Probable Error in Single Measurement/(Number of Observations^0.5)
Mean Error given Sum of Errors
​ LaTeX ​ Go Error of Mean = Sum of Errors of Observations/Number of Observations
True Error
​ LaTeX ​ Go True Error = True Value-Observed Value

Observed Value given True Error Formula

​LaTeX ​Go
Observed Value = True Value-True Error
x = X-εx

What is a True Value?

The true value of a measurement can never be found, even though such a value exists. This is evident when observing an angle with a one-second theodolite; no matter how many times the angle is read a slightly different value will always be obtained.

How to Calculate Observed Value given True Error?

Observed Value given True Error calculator uses Observed Value = True Value-True Error to calculate the Observed Value, The Observed Value given True Error formula is defined as the true error and true value of the surveying. It is calculated from the instrument directly. Observed Value is denoted by x symbol.

How to calculate Observed Value given True Error using this online calculator? To use this online calculator for Observed Value given True Error, enter True Value (X) & True Error x) and hit the calculate button. Here is how the Observed Value given True Error calculation can be explained with given input values -> 160 = 480-320.

FAQ

What is Observed Value given True Error?
The Observed Value given True Error formula is defined as the true error and true value of the surveying. It is calculated from the instrument directly and is represented as x = X-εx or Observed Value = True Value-True Error. True value is the actual value of any process done in survey & True error is the difference between the true value of a quantity and its observed value.
How to calculate Observed Value given True Error?
The Observed Value given True Error formula is defined as the true error and true value of the surveying. It is calculated from the instrument directly is calculated using Observed Value = True Value-True Error. To calculate Observed Value given True Error, you need True Value (X) & True Error x). With our tool, you need to enter the respective value for True Value & True Error 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 Observed Value?
In this formula, Observed Value uses True Value & True Error. We can use 2 other way(s) to calculate the same, which is/are as follows -
  • Observed Value = True Error/Relative Error
  • Observed Value = Residual Error+Most Probable Value
