Statistics is a branch of mathematics that deals with collection of data, analysis of the collected data and using results to give the out information which can used to draw inferences on the premises of their quantifiable probability or likelihood. Statistics is a general term used to outline a procedure that a mathematician or analyst can use to portray an information set. On the off chance that the information depends on a bigger population, then the analyst can develop deductions onto the population in view of the factual results from the sample. Being a statistician allows you to work in any field – psychology, biology, economics, astronomy, genetics, engineering, medicine, public health, marketing, sports, and education among many others.
Statisticians give important information in figuring out what data is solid and which forecasts can be trusted. They frequently hunt for clues of information to the solution of a logical puzzle and at times keep others from being deluded by false impressions.
Branches of statistics
All statistics students ought to be aware of the branches of statistics to effectively comprehend statistics from a more all encompassing perspective. Regularly, the sort of occupation or work one is involved with tends to conceal parts of statistics, however it is essential to know the general idea behind statistical examination to completely understand its significance. The two principle branches of statistics are
1) Descriptive statistics and
2) Inferential statistics.
They are both used in scientific analysis of data and are equally important for the student of statistics.
1. Descriptive statistics
Works with the concept that statistics concentrates on gathering, outlining, and presenting data or an arrangement of information. This is the primary part of a statistical investigation. It is normally not as easy as it sounds, and the analyst should know about planning tests, picking the right method of gathering data and avoid being biased so as to affect the experiment. Different fields of study require different types of analysis utilizing descriptive statistics. For example the mean age of voters who choose the Senator, the average length of novels or the mass variation of say packets of cereal from the production line of a plant. This is the branch of statistics that most people are acquainted with since numerous examples emerge in ordinary life.
2. Inferential Statistics
With this branch of statistics, it analyzes sample data then one goes on to draw conclusions about the whole population from the sample data. Also as the name proposes, it includes making the right conclusions from the statistical examination that has been performed utilizing descriptive statistics. The derivations make study vital and this aspect is managed in inferential statistics.
While making inferences, one should be extremely cautious so as not to draw the wrong or one-sided conclusions. Despite the fact that this seems like a science, there are routes in which one can control studies and results through different means. For instance, information digging is progressively turning into an issue as computers hold lots of data and it is simple, either deliberately or accidentally, to utilize the wrong inferential method. When you utilize inferential statistics, you begin with a theory or hypothesis and hope to see whether the information correlate to that theory or hypothesis.
Both descriptive and inferential statistics go side by side and one can’t exist without the other. Reliable scientific methods should be followed in both these statistical examination and both these branches of statistics are critical for the researcher.
