Inference


Statistical inference refers to methods that provide the analyst with the
necessary tools to making decisions under uncertainty.



Examples

1. A manager wants to know the behavior of individuals towards the consumption
of electronics. The manager would like to know how much on average individuals
spend in electronics, and a range of expenditures involving about 95% of the
population.

2. Another manager is interested in estimating the purchasing decisions of men
and women of, say, cereal breakfast. The question that statistical inference
would allow to answer refers to whether there are significant differences in
purchases of ceral breakfast for men and women.
