The topic for discussion in the Forum of Unit 6 are mathematical models and how good they should fit reality. In this Forum we would like to return to the same topic subject, but consider it specifically in the context of statistical models.
Some statisticians prefer complex models, models that try to fit the data as closely as one can. Others prefer a simple model. They claim that although simpler models are more remote from the data yet they are easier to interpret and thus provide more insight.
What do you think? Which type of model is best to use?
When formulating your answer to this question you may think of a situation that involves inference that you do and need to present to other people. Would the consumers of your analysis benefit more from you having used a complex model of from yo having used a simpler model? What would be the best way to report your findings and explain them to the consumers? (200 words)

Mathematical models are used as tools to describe reality. These
models are supposed to characterize the important features of the
analyzed phenomena and provide insight. The normal distribution is
an example of a random variable that is widely used by researchers
to model real data.
Researchers often model real observations using the normal
distribution, but sometimes the real distribution is a bit
different from the perfect, normal distribution. List some
reasons why researchers might make approximations like this and
describe...

How many siblings do you have? (You may make up a realistic
number if you wish to keep your family information private.)
Which do you think is larger, the mean number of siblings of
people in this class, or the median number of siblings? Why do you
