About Me
I’m Welda Zonor. A Recent UNT Graduate and A Data Enthusiast.
My name is Welda Zonor. I graduated from the University of North Texas with a bachelor’s in information systems. I enjoy studying statistics, and I’m always on the lookout for interesting patterns that might affect people’s lives or the community as a whole. Data has sparked fresh ideas on corporate intelligence and practices. It’s amazing how well it can be used to tell stories. Each data observation contains information on the traits and decisions made by specific individuals, which can be combined and filtered to uncover logical relationships. I want to identify these patterns with you and I appreciate them.
Compiling data can be challenging, but when done effectively, it reveals riches and fascinating stories.
