A friend claims that education (years of school) is normally distributed. You believe she's wrong. A reasonable argument for your point of view is that:

about 50% of individuals have greater than 12 years of schooling.

education outcomes are uniformly distributed (all numbers of years are equally likely).

education has several modes (for example, at 12 and 16 years).

the standard deviation for years of schooling is less than the mean.

None of these are reasonable arguments.

for this to make sense, you have to look at an 'adult' population

perl · Answer

for a young population like age 1-6 , you will have a different 'average' number of years of education

perl · Answer

i think (assuming we are looking at adults), you have different modes

perl · Answer

you have adults that are high school graduates , then you have adults who are 4 year college graduates
