A Data Analyst’s primary responsibility is to collect, organise, and model data.
This process begins with gathering raw data, which is often riddled with errors and inconsistencies. Before any meaningful analysis can occur, this data must be cleaned and transformed into a reliable, usable format. Once prepared, analysts apply statistical methods to model the data, uncover trends, and predict outcomes.
These insights are visualised in reports, extracting the actionable insights and trends demonstrated in the data, that organisations can use to make informed, data-driven decisions.
Types of Data Analysis
There are several different types of data analysis to consider, each serving a distinct purpose.
Descriptive analytics – The most common form of data analysis, descriptive analysis is a summary of what happened. It involves compiling past data into dashboards or reports.
Diagnostic analytics – Taking the insights gained from descriptive analysis, diagnostic analysis looks at the reasons why it happened. Looking at the causes of outcomes and making connections between data and identifying patterns.
Predictive analytics – Using previous data to predict what is likely to happen. This analysis requires statistical modelling to make logical predications of the outcomes of events.
Prescriptive analytics – A highly sought after form of data analysis, prescriptive analysis combines the insights from all the other forms of data analysis to determine the correct course of action and improve decision making.
