Inductive statistics

The goal of inductive statistics is making conclusions about population based on information extracted from random sample.

Inductive statistics handles two types of tasks:
1. Parameter estimates.
2. Hypothesis tests.

How many variables do you want to analyze at a time?
(What are variables?)

a) Single variable

Example: Is the average waiting time in a doctor's office greater than one hour?

b) Two variables

Example: Is there any relationship between gender (X) and year income (Y)?

c) Three and more variables

Example: Is there any relationship between number of products sold by commercial representative (Y) and his/her age (X₁), gender (X₂) and education (X₃)?
