How Are Statistics Used to Make Decisions in the Real World? Statistics are those mathematical equations that can be used to analyze what is happening in the world today. If used correctly, statistics can tell us what happened beforehand and what can happen in the future with some mathematical predictions. There are many areas where statistics are essential. Weather Forecasting - First and foremost, statistics is used for forecasting future weather. The forecasters analyze the previous weather conditions and perform statistical analysis for the weather forecast in the future. Prediction of Diseases - Statistics also assist in predicting different diseases. In other words, through statistics, you can find out which disease caused the most damage to the people. Medicinal practitioners use that information to devise an appropriate treatment for the patient. Consumer Goods - Another most important use of statistics is for consumer goods. Huge retail brands like Walmart keep track of everything with the help of statistics. It helps them counteract with the increased number of clients they deal with daily. Stock Market - Stock Market is another area where statistics help stockbrokers, where statistical computer models analyze and forecast the situation of a country's economy. These worksheets and lessons help students determine the validity of the decisions based on probabilities. We teach them how to interpret the numbers and make a highly qualified decision based on the values.
