True Error Solution

Follow our step by step solution on how to calculate True Error?

FIRST Step Consider the formula

ε x = X - x

Next Step Substitute values of Variables

∴

ε x = 480 - 159

Next Step Prepare to Evaluate

∴

ε x = 480 - 159

LAST Step Evaluate

∴

ε x = 321

How to Evaluate True Error?

True Error evaluator uses True Error = True Value-Observed Value to evaluate the True Error, The True Error is defined as the difference between true value and observed value. It is considered as an unmeasured quantity since true value doesn't exist. True Error is denoted by ε_x symbol.

How to evaluate True Error using this online evaluator? To use this online evaluator for True Error, enter True Value (X) & Observed Value (x) and hit the calculate button.
