The …….. In the ………….. Value and …………. Value of a quantity is called …………..

Answer

To solve the fill-in-the-blank question, we need to identify the correct terms that fit into the provided structure. The question is structured as follows:

"The …….. In the ………….. Value and …………. Value of a quantity is called ………….."

### Step-by-Step Solution:

1. **Identify the first blank**: The first blank refers to the type of difference we are discussing. In the context of measurements, we often refer to the difference between the true value and the measured value. Therefore, the first blank should be filled with "difference".

2. **Identify the second blank**: The second blank refers to the "true value" of the quantity. The true value is the actual value that we are trying to measure. Thus, the second blank should be filled with "true".

3. **Identify the third blank**: The third blank refers to the "measured value" of the quantity. This is the value that we obtain through our measurement process. Therefore, the third blank should be filled with "measured".

4. **Identify the fourth blank**: The fourth blank refers to what we call the difference between the true value and the measured value. This is commonly known as "error". Thus, the fourth blank should be filled with "error".

### Final Answer:
The complete sentence is:
"The difference in the true value and measured value of a quantity is called error."
