The probability distribution for many engineering experiments is approximated by
A) the average (mean) value of the data.
B) a normal distribution.
C) the standard deviation.
D) none of the above.

Question

Quizplus · Accepted Answer

The normal distribution is commonly used to approximate probability distributions in engineering experiments. It is a continuous probability distribution that is symmetrical and bell-shaped, making it a good choice for many experimental data sets. The mean and standard deviation are important parameters for the normal distribution, but they are not always sufficient to fully describe the distribution.
