Statistics at this time has been very influential to the problem of science, industry, or social, first began to learn from the population. The meaning of the population in statistics means that the population can live objects, dead objects, or abstract objects. Population can also be a measurement process in the different, which is known by the term time line.
Perform data collection (data collection) called all the population census. A census of the time and require a high cost. Therefore, statistics are often done in the sampling (sampling), ie, a fraction of the population, which can represent the entire population. Analysis of data from the sample will then be used to colligate entire population.
If the sample is taken quite representative, inferensial (decision making) and the knot that is made from the sample can be used to describe the population as a whole. Methods of statistics on how to take the appropriate sampling technique called sampling.
Many use statistical analysis as the concept of probability respectively. While mathematics is a branch of statistics applied mathematics that uses probability theory and mathematical analysis to obtain the basics of the theory of statistics.
There are two kinds of statistics, namely descriptive statistics and statistics inferensial. Descriptive statistics regarding the description of data, for example, from the average and varians from the raw data; mendeksripsikan using the table-a table or graph so that the raw data more easily "read" and more meaningful. While statistics inferensial more than that, for example, a test hypothetical, make predictions of the future observations, or create a regression model.
Two statistics:
1) Descriptive Statistics (deductive) or simple, the process-level statistics include the method of calculating, or set up, manage, present, and analyze data in order to provide a brief description of a situation.
2) Statistics Inferensial, which provides that the rules or the way that you can use a tool in order to deduce the nature of a general data has been compiled and processed.
