Listings123 - Exploratory Data Analysis & Presentation

Business Problem

Listings123 is an up-and-coming home-sharing service (similar to Airbnb). The company provides an online marketplace that connects people looking to rent their homes or rooms (hosts) with people who are looking for temporary accommodations (guests). ​

 

The CEO wants to expand to new cities but has a problem with raising money for the marketing campaign. The investors and VCs will not fund the campaign until they are presented with data-based evidence on what traits (qualities and actions) make a successful host specifically for Listings123.

Tools used

Exploratory Data Analysis Process

Cleaning of inconsistent, invalid, duplicate, and missing data including the use of ISNUMBER/SEARCH, COUNT/COUNTIF/COUNTA/COUNTUNIQUE, and split text to columns functions. Using INDEX/MATCH formulas to merge tables. As well as using VLOOKUP to identify specific items in the tables.

Insights & Results

The top three traits identified that make a host successful for Listings123 are:

These data-based recommendations were provided to secure funding for the company’s nationwide marketing campaign.
