Question

If a1, a2, a3,…, an​ are \(n\) measured values of a quantity, then the mean value a_m is ______.

Options

• \[\frac{a_1-a_2-\cdots-a_n}{n}\]

• \[\frac{a_1+a_2+\cdots+a_n}{n}\]

• \[\frac{a_1\times a_2\times\cdots\times a_n}{n}\]

• \[\frac{a_1+a_n}{2}\]

Answer 1

If a1, a2, a3,…, an​ are \(n\) measured values of a quantity, then the mean value a_m is \[\frac{a_1+a_2+\cdots+a_n}{n}\].

Explanation:

The mean value is defined as the sum of all measured values divided by the total number of measurements.
