    "content": "## Missing Values Analysis\n\nBased on the analysis of the sales_pipeline table (the largest table in the dataset with 8,800 rows), three columns contain missing values:\n\n### Sales Pipeline Table\n\n1. **close_date** and **close_value**: Both have 2,089 missing values (23.74% missing)\n   - These columns are perfectly correlated in their missingness, which makes sense — deals that haven't closed yet would naturally have neither a close date nor a close value\n\n2. **engage_date**: 500 missing values (5.68% missing)\n   - A much smaller percentage, suggesting most opportunities have an engagement date recorded\n\nThe other tables in the dataset (accounts, sales_teams, products, and data_dictionary) have no missing values in any of their columns.\n\n### Interpretation\n\nThe 23.74% missing rate for close_date and close_value is expected in a sales pipeline dataset — these represent opportunities that are still in progress (deal_stage likely shows 'Prospecting', 'Engaging', or 'Qualified' rather than 'Won' or 'Lost'). The small percentage of missing engage_date values (5.68%) may represent very early-stage opportunities that haven't yet had formal engagement."
