Question: The temperature is measured as 25°C with an error of 1°C. What is the range of possible true values?

Options:

  1. 24°C to 26°C
  2. 25°C to 27°C
  3. 23°C to 25°C
  4. 26°C to 28°C

Correct Answer: 24°C to 26°C

Solution: 

True value can be in the range of (Measured value - Error) to (Measured value + Error) = 25°C ± 1°C = 24°C to 26°C.

Questions & Step-by-Step Solutions

The temperature is measured as 25°C with an error of 1°C. What is the range of possible true values?
  • Step 1: Identify the measured temperature, which is 25°C.
  • Step 2: Identify the error in the measurement, which is 1°C.
  • Step 3: Calculate the lower limit of the true value by subtracting the error from the measured value: 25°C - 1°C = 24°C.
  • Step 4: Calculate the upper limit of the true value by adding the error to the measured value: 25°C + 1°C = 26°C.
  • Step 5: Combine the lower and upper limits to find the range of possible true values: 24°C to 26°C.
  • Measurement Error – Understanding how to calculate the range of possible true values based on a measured value and its associated error.
