Question

tate, with an​ explanation, whether the​ mean, median, or mode gives the best description of the following average. The average number of times that people change jobs during their careers

Answer 1

The median is often a better representative of a typical member
of a group. If you take all of the values in a list, and arrange them in
increasing order the number at the center will be the median. The median
is an actual value belonging to some member of the group - depending on the distribution of values, the mean may not be particularly close to the value of any member of the group; and the mean is also subject to skew - as few as one value significantly different from the rest of the group can dramatically change the mean. The median gives you a central member of the
group without the skew factor introduced by outliers. If you have a normal distribution, then the median value will be a typical member of the population.

Now coming to your question

The average no of times that pepole change jobs during the careers

The median is the best because the distribution is probably right dash skewed with a single peak
