Descriptive and Inferential Statistics

Traditional Statistics

Besides using Big Data and AI to analyse data and conduct research, descriptive and inferential statistics are also used to analyse data sets. These are commonly used when researching groups of people and provide different outcomes. 

Descriptive Statistics are used to provide information based on raw data collected. This usually includes summaries of the data that make it understandable often using different data point like mean, mode, median. This can be used to identify trends and distributions. It is important to note that descriptive statistics don't make any assumptions based on the data and merely provide information based on concrete data. 

Inferential Statistics however use data from a small sample and use that to make assumptions about a broader population. This type of statistic is useful for making connections between different data points, for example linking poverty with higher crime rates. These statistics are only estimates and differentiate from descriptive statistics which use more concrete data points.
