Statistical Analyses

Statistics involves collection, analyses and summarizing of data. Sampling is one of the most important techniques used in statistics that allows a researcher to perform test on a small number of participants whereas, the results of these tests represent the whole population, therefore less work is required and results are achieved quickly (Norusis, 2007).
Before data can be analyzed, data needs to be obtained and the process of obtaining data also involves some measurement processes. Different measurement methods are used and the results obtained are assigned to relevant measurement scales before they can be tested. The data obtained is then classified into different categories as per there class. The result sometimes gets distorted due to a faulty process of obtaining data, which involves the grouping effect where results from data after grouping are different form results obtained before grouping while they both were expected to be same.The second error that sometimes occur is spatial effect in which participants are selected in a way that the result of the group differs from the actual results of the total population.

History of Statistics

The field of statistics is young as compared to other scientific fields and has been studied for almost 150 years however,major works have been carried out during the past century. Many notable statisticians have served it such as Pascal. Historically statistics had been used only on information of a state’s population to decide economic policies, andafterwards they were usedin analyzing temperature records. Researchers of different fields have been using statistical models to further study there relevant fields, therefore it can be said that different statistical concepts have affected broad ranges of fields of science.The main benefit of statistical models is that it allows the designing of experiments; therefore the results obtained are not distorted.
