# What can you measure that will give you a graph of normal distribution?

A pedantic answer would be nothing!

The number of heads from repeated tosses of a fair coin will give an

approximately normal distribution. But if the distribution is truly normal then

there is an infinitesimally small, but non-zero, probability of getting a negative

Similarly, the heights of adult males, for example, is usually assumed to be

normally distributed. Again the distribution should have a very, very tiny - but

non-zero - probability of an adult male having a negative height! Somehow I

don't think so!

Hence the mathematically accurate answer is nothing.

The coin-tossing experiment will generate a very good approximation of a Normal

distribution when the coin is fair, as will men's heights. An even better

approximation will be obtained if you take lots of random samples of 10 men and

observe the sums or means of their heights. Women's heights, their masses,

IQs (whatever that is supposed to measure), will all be normal.

The question that has not been adequately researched is whether it is the IQ

of all people that is normal, or of only normal people.
