Data Cleaning and Outlier Identification

$5/hr Starting at $25

1.Client's Goal for the Project: The client sought a skilled Data Science professional to enhance the quality and reliability of the 'Shoppe.com' dataset through comprehensive data cleaning and outlier identification. The primary objectives included standardizing 'ProductID,' handling missing values in critical columns ('ProductName' and 'Category'), addressing outliers in the 'Price' column, and ensuring data integrity for subsequent analytical and statistical endeavors. 2.Details about My Contribution to the Project: As a dedicated Data Science enthusiast, my contributions to the project were substantial. I successfully implemented the following key steps: A).Data Cleaning: Standardized 'ProductID' by removing non-numeric characters, ensuring a consistent format for product identification. Replaced 'INVALID' entries in 'ProductName' and 'Category' with NaN, enhancing data consistency. Imputed missing values in 'ProductName' and 'Category' based on the most frequent values within corresponding groups, addressing data completeness. Handled empty 'ProductID' entries by replacing them with NaN, ensuring uniformity and reliability in product identification. B).Outlier Identification and Treatment: Identified and addressed outliers in the 'Price' column using the IQR method, contributing to a more accurate analysis of pricing information. Retained missing values in the 'Discount' column, strategically avoiding potential distortions in statistical analysis and maintaining the dataset's integrity. Conducted comprehensive statistical analysis on 'Discount' and 'Price,' providing valuable insights through mean, median, kurtosis, and skewness calculations. C).Duplicate Handling: TotalPrice, ProductName, and Quantity typically do not contain duplicate values because they represent unique aspects of transactions or items, such as total cost, product identity, and quantity purchased or sold. D).Summary and Visualization: Provided detailed statistics on the cleaned data, including mean, median, and descriptive statistics, offering a clear understanding of the dataset's characteristics. Generated insightful visualizations, such as box plots and scatter plots, to illustrate data distribution and highlight potential outliers. 3.Summary of the Project Success: The final clean dataset, denoted as 'df1,' is a testament to the project's success. With 823 rows and 7 columns, the dataset is now well-prepared for diverse analytical and statistical operations. This project's success lies in the elimination of redundancies, meticulous handling of missing values, and strategic treatment of outliers. The result is a reliable foundation for data-driven decision-making, enhancing the dataset's quality and ensuring its suitability for various analytical endeavors.
