Statistics as a numerical fact is a piece of numerical information, also known as data, used to describe an event, occurrence or phenomena. Statistics as a discipline uses statistics or numerical pieces of information to solve problems in the everyday world and in academics. Those who work with statistics as a discipline are called statisticians.Know More
The discipline of statistics covers several areas of science and industries, including the environment, health and epidemiology, computer science and astronomy. Statisticians may also work in education, engineering and in other non-science sectors such as business. Work is done primarily in an office setting, but they may also travel to sites to collect data to analyze later.
Statisticians may work for government or in the private sector. Statistician positions generally require a graduate degree in mathematics or statistics, but some jobs may only require a bachelor's degree. Statisticians present their data through several graphs and plots such as pie or chart graphs, bar graphs and stem and leaf plots.
Statistics may be descriptive or inferential. Descriptive statistics describe features of the population or sample being studied and includes measurements such as mean, median and mode. Inferential statistics involve inferring something about the population studied. This process is done through hypothesis testing.Learn more about Statistics
The type of math scientists use to analyze data is called statistics. It enables researchers to learn from numbers by measuring, controlling and communicating degrees of certainty and uncertainty, as explained by the American Statistical Association.Full Answer >
Inferential statistics is a branch of statistics that can be used when researchers and mathematicians want to attempt to extrapolate on and reach conclusions that extend beyond the raw data itself. While a study only uses a small sample of the total population it is studying, inferential statistics can be used to attempt to estimate traits and thought patterns of behavior among the population as a whole.Full Answer >
The purpose of statistics is to allow sets of data to be compared so that analysts can look for meaningful trends and changes. Analysts review the data so that they can reach conclusions regarding its meaning. Statistics allow people to see how things are or are not correlated and how a change in one variable might affect another.Full Answer >
Experts use statistics to understand large and complex sets of data. Statistics are also helpful with surveys, which legislators use to affect policy. Knowing how statistics work is important for fully understanding news reports.Full Answer >
