This assignment provides you an opportunity to utilize the functions a This assignment provides you an opportunity to utilize the functions and tools of Excel to solve a basic analytics scenario: data validation. The purpose of this assignment is to use Excel to quickly identify the possible errors within the database, and not to visually examine all 6,000+ database records. The HR tab in Hospital.xlsx file contains the employee records downloaded from the Human Resource database of a fictitious hospital. As with any acquired data, you must be aware of the limitations of your dataset. The sourcing database for Hospital.xlsx has a limit of twenty (20) characters for the Address 1 and Address 2 fields. Therefore, truncated addresses are not considered errors. The only errors in the Address fields that can be easily identified in Excel would be a missing address or an address of insufficient length to contain a deliverable address. Six characters is the minimum length for an address (e.g. “1 U Stâ€.) To accurately identify the possible errors in the Address 1 field, through Excel, you would need to create a parsing algorithm to correctly determine the components of an address including the primary address number, pre-directional, street name, suffix, post-directional, secondary address identifier, and secondary address. Compound this with the Address 1 truncation issue and the creation of such an algorithm would be way too advanced for this course. Therefore, there are NO Address 1 fields errors except a missing address or an address of insufficient length to contain a deliverable address. Data is required in all fields except Address 2 and Phone. If a phone number is entered it must adhere to the format. No rules concerning cases exist for any field. Both five-digit zip codes and zip+4 zip codes are allowed in the Postal Code field. Also, remember that a zip code may have more than one authorized city or spelling. Only one US zip code in Arizona (85142) crosses county

Introduction The purpose of this analysis is to conduct data validation within the Hospital.xlsx dataset, particularly focusing on identifying errors in the employee records, such as missing or insufficient addresses, incorrect postal codes, and invalid phone numbers. Effective data validation enhances the accuracy and reliability of hospital data, which is essential for operational efficiency and patient care. Methodology The approach involves using Microsoft Excel's functions, including lookup, reference, logical, and text functions, to systematically identify record errors. Filtering and sorting capabilities in Excel were employed to manage the large dataset of over 6,000 records. Additional reference material from Zipcode.xlsx was used to validate postal codes and associated cities. Data Validation Procedures Address Validation Given the limitations of the Address 1 and Address 2 fields, the primary validation was to check for missing addresses and addresses with less than six characters. A formula was created using the LEN function to identify records with addresses shorter than six characters, indicating potential errors. =IF(LEN([Address1]) Furthermore, due to the limitations of parsing algorithms at this level, the addresses were not further dissected into components. Instead, the focus was on detecting missing data which could compromise delivery or address validation. Postal Code Validation Postal codes were validated against known zip codes using lookup functions like VLOOKUP to cross-reference with Zipcode.xlsx. An incorrect or invalid zip code was flagged if it did not match entries in the reference file. =IF(ISNA(VLOOKUP([PostalCode], Zipcode Range, 1, FALSE)), "Invalid ZIP Code", "Valid") It was also noted that some zip codes correspond with multiple cities; this was cross-verified manually where necessary, especially for the Arizona zip code 85142 crossing county lines. Phone Number Validation Phone numbers were checked to ensure they adhered to the
