Process of Data Analytics: How Does Data Analytics Work?

For data to be converted into meaningful information, there are various sub-processes that have to be undertaken. The data analytics process typically involves the following key steps:

1. Data Collection: Gather important data from diverse sources such as databases, APIs or sensors.

2. Data Cleaning: Remove inconsistencies, errors and outliers within the data collected for accuracy necessitation.

3. Data Processing: Refashion the cleaned data into a suitable format for analysis.

4. Data Analysis: Use statistical and computational methods to scrutinize the processed data and bring out patterns, trends and correlations which can be used to draw conclusions.

5. Data Visualization: Represent analyzed information using graphical display on charts, graphs or dashboards for ready understanding and interpretation by others.

6. Data Interpretation: Elucidate Decision Making resulting from Data Presented Graphically .

This lifecycle enables businesses to tap into data analytics for ongoing optimization and innovation. The process requires coordination across teams to ensure alignment between technical and business goals.

Types of Data Analytics

There are three main types of data analytics:

1. Descriptive Analytics: Summarizes what happened in the past using historical data. Metrics and reports are used to understand performance.

2. Diagnostic Analytics: Analyzes past data to understand why something happened. Drills down into factors behind metrics.

3. Predictive Analytics: Uses statistical and machine learning models to forecast future outcomes and trends. What could happen next?

4. Prescriptive Analytics: Combines predictive insights with business goals to recommend data-driven decisions. What action should be taken?

5. Automated Analytics: Uses AI and ML models to automatically analyze data and take actions such as predicting churn or blocking fraudulent transactions.

Each type provides additional business value and continues progressing up the analytical maturity curve.
