Question

A line midway between two parallel straight lines close together and enclosing all output versus measurand values, on a calibration curve is termed as ______________

(a) analog signal

(b) best fit straight line

(c) ambient condition

(d) none of the mentioned

I got this question in an online interview.

I want to ask this question from Measurement of Temperature topic in section Engine Electronics of IC Engine

Answer 1

The correct answer is:

(b) best fit straight line

In the context of a calibration curve, the best fit straight line refers to a line that best represents the relationship between the output and the measurand values, typically minimizing the errors in the measurements. This line is often drawn midway between two parallel straight lines that enclose the output values, providing the most accurate and reliable representation of the measurement data.
