How to Become a Statistician
If you are a high school student, take all of the mathematics, science, computer and English courses you can.
You will need mathematics to understand the language and theory of statistics. You will use the computer not only for calculations but also to create visual displays of data.
Scientific knowledge will help you understand the technical background of the problems you work on and will make you a more effective problem solver. Command of written and spoken English will help you to effectively communicate the conclusions you have reached.
If you are a college student, consider either a major in statistics or a major in a related field such as economics, biology, finance, etc. supplemented with courses in statistics. Build up your background in mathematics and computer courses. You may even want to consider a double major of statistics and some related field.
