# What is Statistics?

Statistics is the process of gathering, organizing, presenting, analyzing, and interpreting data. This is done in order for the data to be used for making more sound decisions. This whole discipline of statistics is the fundament of many current and future businesses.

The whole idea behind statistics and statistical analysis is to provide a more conceptual framework. What this means is that it enables various structured ways of thinking. But this is not all. It also offers practical skills so that the students will be better furnished for the future.

Statistics helps us make educated guesses of the unknown and get useful information in the ocean of data. Statistics can be divided into several areas: sampling methods, descriptive statistics, and inferential statistics.

In sampling methods, we cover the way we collect data. This is the most vital element of statistics. It is necessary as it ensures that we organize our data the right way. And, then we can make valid conclusions as time goes on. It is also helpful for giving us insights into the quality of the information for later analysis.

There are two fundamental ideas of statistics. These are uncertainty and variation. In life, there are many situations in which we cannot tell the outcome of certain conditions. This happens in science, as well. The reason for this uncertainty is typical because the result that we have in question is not determined. For example, we do not know for sure if there will be rain tomorrow. In other cases, uncertainty occurs because we don't know about it. An example would be uncertainty about the grade of an exam.

On the other hand, the variability typically refers to a large number of values one quantity has. This includes time, different locations, and other instances such as the collection of various varying reservoirs and the average porosities. A probability distribution can measure this concept in statistics. This projection represents the probability of the indefinite quantity's actual value in our state of knowledge. Variability is measured by the descriptive statistics of multiple quantities generated from observational data.

In definition and analysis, distortion of facts can create subtle yet severe mistakes, mild in the way that even professional people make these mistakes, and profound in the meaning that they can result in severe decision errors. Public policy, the practice of medicine, and the reliability of frameworks like roads, for example, rely on the appropriate use of data.

When statistical methods are interpreted correctly, the conclusions may be hard to comprehend for those lacking experience. The statistically significant difference of a data trend, which calculates the extent to which a pattern may be induced by average variance in the study, may or may not agree with an intuitive understanding of its importance. The collection of fundamental statistical abilities (and pessimism) that individuals need to deal with information in their regular lifestyle effectively refers to statistical literacy.

Using proper diagrams and avoiding bias are methods of preventing exploitation of statistics. When conclusions are overgeneralized and claimed to represent more than they are, misuse may occur, often by ignoring selection bias deliberately or unintentionally.
