- Data Collection and Cleaning: Gathering data from various internal and external sources, followed by cleaning processes to ensure data accuracy and consistency. This includes filtering errors, handling missing values, and maintaining the reliability of analyses.
- Exploratory Data Analysis (EDA): Using statistical tools to understand data distributions, detect patterns, relationships, and anomalies, and conduct descriptive statistics to gain an initial understanding of the dataset.
- Statistical Analysis and Modeling: Applying advanced techniques such as hypothesis testing, regression, clustering, and trend analysis to derive meaningful insights and uncover hidden relationships within the data.
- Data Visualization and Reporting: Creating clear and compelling visualizations to communicate complex data insights effectively to various stakeholders through charts, graphs, dashboards, and comprehensive reports.
- Business Insight and Recommendations: Interpreting analytical outcomes and converting them into actionable business strategies and recommendations that aid departments in optimizing performance and decision-making.
