Statistical data dates back to as early as Ancient Greek time, where it was introduced by John Graunt, William Petty and Pascal in the 16th century. It was then re-introduced by Gottfriend Achenwall in the 17th century. This was a very exciting time for scientists, astronomers and physicists alike as it raised the confidence and knowing that the laws of nature were not of divine intervention. As the years went on, new mathematical discoveries were made such as census data, economy, mortality demographics, and the International Statistical Congresses, which all led to changing its name to “statistics”. Population
Every decade the US government conducts a census on the population. The data provided in this census is then used for reseach purposes, business marketing, planning, and various other sampling needs. This leads to the question of “What is population?” This can be defined as people that occupy a town which is located in specific region within a specific county/state, and their individual characteristic such as sex, age, ethnicity or marital status. The term “population” is made up of all members and/or elements in that defined group. The basic topics covered in population are birth, growth, age and death.
The statistic term Sample
In order to obtain statistical data, there are various factors that need to be collected, analyzed and then summarize to come to an appropriate conclusion. In order to collect a certain amount of data from the population, a sample will need to be performed. The sample techniques that are utilized, are done so to save time. These methods are suitable for different types of data and they can also save money. The main point is to test all the factors in order to obtain accurate and reliable results.
