Introduction to Statistics

Statistics is the branch of mathematics that deals with collecting, organizing, analyzing, interpreting, and presenting data. It helps us make sense of information and draw meaningful conclusions from observations.

Key Concepts:

  • Data: Information collected through observation or measurement
  • Population: The entire group being studied
  • Sample: A subset of the population used for analysis
  • Variable: A characteristic or attribute that can vary

Example:

If you want to know the average height of students in your school, you could:

  • Population: All students in the school
  • Sample: 50 randomly selected students
  • Variable: Height (in centimeters)
  • Data: The measured heights of the 50 students
