Practical Applications of Statistics
Statistics can help psychologists
Hi! I’m Ben Owens, math educator at the University of North Texas. In this video for About.com, I’ll talk about some practical applications of statistics. Statistics is the study of numerical information, or data. And believe it or not, it’s everywhere around you: in newspapers, on TV, and in a variety of fields and applications. Take psychology. A regular therapist might see several hundred people in a year. He might see people with ADHD, psycho-social behaviors, anger management issues, and so forth. The therapist could summarize his observations, to develop an awareness of the differences and similarities across all his patients. He could diagnose someone with ADHD, for example, and through his records and experience with other patients, estimate the likelihood this patient might also experience anger management issues. Statistics can help in psychologists see patterns and formulate hypotheses on patients. Statistics is also very important in economics. Say, a country is having financial problems. Economists can gather data on the country’s import, export, jobs, (and so forth), and determine the likelihood of the country getting out of debt. So, statistics can help economists grow in knowledge, and formulate predictions based on gathered data. And even in journalism statistics is very important. Journalists are also known as conveyers of information, and so they need to have a basic understanding of statistics. Say, for example, a town hall meeting is being called on a city’s budget for recycling. In order to effectively write a story, journalists will have to understand the impact of numbers, and be able to calculate and understand budgets and reports. Statistics is also used in advertising. & nbsp;In modern times, companies such as Google and Facebook use the internet to gather data about individuals. They use data, and therefore statistics, to help market products to consumers who are more likely to buy them. So, as you can see, statistics applies to a lot of different fields!
