What are statistics?

Statistics – the math and science of data collection, analysis, visualization, and interpretation. Typically paired with the study of probability, the study of likelihoods for a particular event, statistics can also be described as the study of events given a series of probabilities. A statistic on the other hand, is the result that is yielded after data is analysed. A statistic can be described as descriptive or inferential. Descriptive statistics provide general summaries such as the distribution, spread and centre of a dataset. Inferential statistics involves data analysis on just a sample of the population to make inferences on the larger population as a whole.

Statistical thinking will one day be as necessary a qualification for efficient citizenship as the ability to read and write.
H.G. Wells

As suggested by Wells, Statistics math and probability math are both important topics you will likely encounter or require further on in life. At the very least, statistics are paramount in helping make major decisions that will have some effect on you. Governments are frequently tasked with collecting statistics from the population to inform them on the status of issues and how they can better serve the public. Academically speaking, be it in this course, an introduction to statistics course, probability and statistics or introduction to probability class, the purpose and study of statistics is to equip with you with strong mathematical induction and deduction skills when faced with data. Furthermore through exposure of the best practices in data collection, data analysis, data representation, and interpretation, the study of statistics aims to improve your analytical and problem-solving skills.

    This website saved my butt last semester. I am using it againthis semester. Dennis is the best online tutor... I also like that I can watch videos over and over until I really understand the concept. If you want to save time, sign's only ten bucks and it saved me hours of study time. Thanks, Dennis!

  • Aaron M.
    high school student

    I get a whole library of videos that covers everything from basic to complex mathematics for a very low monthly price. Excellent videos, easy-to-understand and most of all they work. My math test results are 10 points higher than last semester.
