Types of data analytics

Data analysis is a wide range of fields. There are four main types of data analysis; each type has different goals and locations for the data analysis process. 

Data Science

Descriptive analysis: These procedures summarize extensive datasets and define the results to stakeholders. These strategies track success or failure by forming key performance indicators (KPIs). Indicators like ROI (return on investment) are utilized in many industries. Detailed metrics have been designed to track the performance of a specific sector. This procedure demands gathering relevant data, processing the data, interpreting the data, and visualizing the data. This process provides critical insights into the past interpretation.

Diagnostic analysis: These techniques complement the more fundamental descriptive analysis. They take findings from descriptive analysis and go more in-depth to find the cause. KPIs are further analyzed to determine the reason behind their performance. This usually happens in three steps; Firstly, data anomalies are identified. These can be metrics or unexpected changes in a particular market. Then data related to these anomalies will be compiled. Lastly, statistical techniques are used to see relationships and trends that define these anomalies.

Predictive analytics: These techniques employ historical data to determine trends and if they are likely to recur. Predictive analytics tools provide practical insights into what will happen in the future, including different statistical and machine learning approaches like neural networks and regression.

Prescriptive analytics: You can make data-driven decisions employing predictive analytics insights. It allows corporations to make educated decisions in the face of uncertainty. Their techniques depend on machine learning techniques to discover patterns in enormous datasets. You can assess the potential for various outcomes by analyzing past choices and events.

Core skills for analytics

A / B testing:  Simply, it is a statistical approach that compares two variable versions in a controlled environment. It is used to specify which variable version is functioning better than the others.

Programming: A data analyst must have brilliant programming skills in languages ​​like Python and R.

Domain knowledge: It can be considered a specialty, like you know the industry, if you have a lot of work background and necessary expertise, especially in the retail sector.
