The two main branches of statistics are descriptive statistics and inferential statistics.

Statistics is the science deals with collection, classification, summarizing, organizing and interpretation of data to make inference and draw conclusions based on data. While statistic (as a singular) is a single measure of some attribute of a sample.

Consider statistics as a problem-solving process and examine its four components: asking questions, collecting appropriate data, analyzing the data, and interpreting the results.

Descriptive statistics is used to summarize and describe data, while inferential statistics is used to make inferences and predictions about a population based on a sample of data.
