What's included

  • Data Cleaning Report

    I will deliver a report detailing the data cleaning process, outlining the steps taken to clean the data, including handling missing values, outlier detection and treatment, data transformation, and any other necessary data cleaning techniques. The report will include any assumptions made and decisions taken during the cleaning process.

  • Cleaned Dataset

    I will deliver a cleaned dataset, ready for further analysis and modeling, in a suitable format, with properly labeled columns and rows.

  • Exploratory Data Analysis (EDA) Report

    I will deliver an EDA report that explores the cleaned dataset, including descriptive statistics, visualizations, and key insights gained from the data analysis. This analysis will help stakeholders understand the characteristics, patterns, and relationships present in the data.

  • Data Quality Assurance

    I will provide an assessment of the data quality after cleaning, including metrics such as the percentage of missing values, data completeness, consistency, and data integrity. I may also offer recommendations for data quality improvement if applicable.

  • Extract Transform Load (ETL) Report

    I will provide an ETL report to include extraction methods if external data sources are used, a source-to-target mapping data transformation table, and notes and/or queries used to load data into databases or other storage. This documentation ensures reproducibility of the work done.

  • Data Analysis Models

    I will deliver data analysis models developed using the cleaned dataset, in a persisted format. As applicable to the client's individual project needs, this may include predictive or diagnostic models, classification models, clustering algorithms, or any other relevant analytical techniques. I will also provide documentation or code explaining the model's implementation and insights gained from the analysis.

  • Visualizations and Dashboards

    I will create visualizations and/or interactive dashboards that effectively communicate the insights and patterns found in the data and enable stakeholders to explore and interact with the data.

  • Recommendations and Actionable Insights

    **PREMIUM FEATURE** I will provide an executive summary of key findings and provide actionable insights based on the data analysis, plus offer recommendations or suggestions on how the insights can be used to drive decision-making or solve specific business problems.

  • Presentation or Workshop

    **PREMIUM FEATURE** I will conduct a presentation, conference call, or workshop to share the results, insights, and recommendations with stakeholders. This allows for a collaborative discussion and ensures that the findings are clearly understood and can be applied effectively.
