What is Statistics?
Statistics is the term used in mathematics to describe the study numerical data collection, organization, and interpretation. Regardless of the group size, statistics requires analytical and inference skills to draw accurate conclusions about the quantitative and observed data. Due to the complexity of looking at data with many variables, characteristics, or traits specific to an item, statisticians rely on differential and integral calculus, linear algebra, and probability theory.
Descriptive and inferential statistics are the two major areas used to study and analyze the properties of the sample and quantitative or qualitative data population. These properties are then used to test hypotheses, analyze variables, interpret outcomes, and draw conclusions. Statistics rely on multiple levels of measurement to quantify the results. Once collected and analyzed, data can be presented in various ways, including bar graphs, pie charts, line graphs, pictographs, histograms, and frequency distribution charts.
Statistics are used in a wide variety of professions and career fields, as well as in everyday life. Statistics are applied whenever data is collected, organized, and interpreted. The information provided through the use of statistics gives insight into how and why things work. Using statistics in the way of research, evaluation, and analysis of outcomes helps everyone, from government and investment agencies to weather forecasters to geologists, make sound decisions.
As with all forms of mathematics, statistics is complex and relies on knowing and understanding various other skills. These skills include the principles of probability and the testing of hypotheses, reiterating that having a strong foundation in mathematical practices will further develop a deeper understanding of statistics.
