Probability is the study of chance and is a very fundamental subject that we apply in everyday living, while statistics is more concerned with how we handle data using different analysis techniques and collection methods. Inferential Statistics . Mathematics is the abstract science of numbers, quantity and space. The collection of data about states and localities continues, largely through national and international statistical services. When we begin with a sample and then try to infer something about the population, we are using inferential statistics.In working with this area of statistics, the topic of hypothesis testing arises.
