Question 698563
Examine the intelligence quotient, or IQ, as it is defined by the formula: 
“intelligence quotient = 100 * (mental age/chronological age)”
Justify why it is reasonable for the mean to be 100. 
-----
If your mental age is equal to your chronological age you are
an average person, neither smarter or dumber than other people.
----
In that case your IQ = 100*(your mental age your chron age) = 100*1 = 100
