There are two general branches of Statistics: Descriptive statistics is the branch of statistics used in describing the data (via graphs, tables or sample stats like mean) and Inferential statistics is the branch that deals with inferring/estimating population characteristics from sample data. The fomer can be summaries as, "You have a pile of data and you want to summarize it appropriately," while the latter can be summarized as "The idea is if a sample accurately represents the population it came from then analyzing the sample will lead to important conclusions about the population as a whole."
