Statistics Two main statistical methods are used in data analysis: descriptive statistics, which summarizes data from a sample using indexes such as the mean or standard deviation, and inferential statistics, which draws conclusions from data that are subject to random variation (e.g., observational errors, sampling variation).

Types of Regression Models. Regression analysis is an important tool for modelling and analyzing data. Here, we fit a curve / line to the data points, in such a manner that the differences between the distances of data points from the curve or line is minimized. I’ll explain this in more details in coming sections.

The 3 Basic Types of Descriptive Research Methods Descriptive research methods are pretty much as they sound — they describe situations. They do not make accurate predictions, and they do not determine cause and effect. There are three main types of descriptive methods: observational methods, case-study methods and survey methods.

- Item Analysis describes the statistical analyses which allow measurement of the effectiveness of individual test items. An understanding of the factors which govern effectiveness (and a means of measuring them) can enable us to create more effective test questions and also regulate and standardise existing tests. There are three main types of Item Analysis: Item Response Theory, Rasch Measurement and Classical Test Theory. Classical Test Theory (traditionally the main method used in the United Kingdom) utilises two main statistics-Facility and Discrimination. The main problems with Classical Test Theory are that the conclusions drawn depend very much on the sample used to collect information.

- Qualitative analysis gives an indication of the identity of the chemical species in the sample, and quantitative analysis determines the amount of certain components in the substance. The separation of components is often performed prior to analysis. Analytical methods can be separated into classical and instrumental.
