Business And Research Statistics

Bringing knowledge out of the realm of uncertainty

Business and research statistics can be very valuable to your business. These analysis methods are a way of analyzing it. They can give you the big picture of where you are now, control processes within your business and forecast where you are going. Consider this section of the website as a way to get free probability and statistics training.

Statistics is an applied science used to discover facts and relations concerning the subject under study.

Statistics take into account the uncertainty factor. Most all of mankind's endeavors have a random factor. A good example is weather forecasting. The weatherman is communicating that uncertainty when he states that there is a 30% chance of rain tomorrow. Statistics is a way of putting numbers to that randomness.

Business and research statistics is relevant to most areas of the business world. Statistics is important to business analysis in the fields of manufacturing, agriculture, pharmaceuticals, retail and in many others.
