Transcription: The branch of mathematics concerned with collecting and interpreting data is called statistics. The data are often collected by interviewing a sample group of people who are meant to represent the whole population. If the sample group has been put together carefully, the findings should be fairly accurate for the entire population. The information gained from the sample group can be very useful to government agencies and businesses, helping them find out tastes, opinions, and the probable outcome of events.
