Statistical Data Analysis

The purpose of statistical analysis is to determine data trends. There are two statistical methods: descriptive and inferential statistics.

Descriptive statistics: A statistic is a number that is obtained from data, for example, an average or a standard deviation. It can be very helpful when examining data to get a suitable group of relevant descriptive statistics. Especially, it can be very interesting to study statistics obtained from different (but related) columns, or between levels of a factor. This gives an idea of the similarities or differences between the data.

Inferential statistics: After data exploration, with the help of visualization and description techniques, one will need to determine what formal statistical analysis technique is required to investigate the data further and to come to general conclusions. A large number of statistical techniques have been developed to deal with many different types of data and create relationships between them.

A subject specialist will ensure a robust study design.
