Cross Validated is a question and answer site for people interested in statistics, machine learning, data analysis, data mining, and data visualization. It only takes a minute to sign up. My understanding was that descriptive statistics quantitatively described features of a data sample, while inferential statistics made inferences about the populations from which samples were drawn. However, the wikipedia page for statistical inference states:. For the most part, statistical inference makes propositions about populations, using data drawn from the population of interest via some form of random sampling. The "for the most part" has made me think I perhaps don't properly understand these concepts. Are there examples of inferential statistics that don't make propositions about populations?

Statistics analysis provides you with the best information on methods to collect data. Data collection helps you make informed decisions in the workplace while rendering evidence that's beneficial in achieving your goals.

A descriptive statistic in the count noun sense is a summary statistic that quantitatively describes or summarizes features from a collection of information , [1] while descriptive statistics in the mass noun sense is the process of using and analysing those statistics. Descriptive statistics is distinguished from inferential statistics or inductive statistics by its aim to summarize a sample , rather than use the data to learn about the population that the sample of data is thought to represent. This generally means that descriptive statistics, unlike inferential statistics, is not developed on the basis of probability theory , and are frequently non-parametric statistics. For example, in papers reporting on human subjects, typically a table is included giving the overall sample size , sample sizes in important subgroups e. Some measures that are commonly used to describe a data set are measures of central tendency and measures of variability or dispersion.

Statistics is concerned with developing and studying different methods for collecting, analyzing and presenting the empirical data.

Он почувствовал неимоверный жар, бегущий вверх по руке. Нестерпимая боль пронзила плечо, сдавила грудь и, подобно миллиону осколков, вонзилась в мозг. Клушар увидел яркую вспышку света… и черную бездну. Человек ослабил нажим, еще раз взглянул на прикрепленную к спинке кровати табличку с именем больного и беззвучно выскользнул из палаты.
