5 * This method is like `_.mean` except that it accepts `iteratee` which is
6 * invoked for each element in `array` to generate the value to be averaged.
7 * The iteratee is invoked with one argument: (value).
8 *
9 * @static
10 * @memberOf _
11 * @since 4.7.0
12 * @category Math
13 * @param {Array} array The array to iterate over.
14 * @param {Function} [iteratee=_.identity] The iteratee invoked per element.
15 * @returns {number} Returns the mean.
16 * @example
17 *
18 * var objects = [{ 'n': 4 }, { 'n': 2 }, { 'n': 8 }, { 'n': 6 }];
19 *
20 * _.meanBy(objects, function(o) { return o.n; });
21 * // => 5
22 *
23 * // The `_.property` iteratee shorthand.
24 * _.meanBy(objects, 'n');
25 * // => 5
