Data 101: Understanding Statistical Significance
It has been a while since the last Data 101 episode; things have been busy! For this new post, I want to break down one of the most common (and commonly misunderstood) concepts in data analysis: statistical significance, p-values, And the basic idea behind hypothesis testing What is Statistical Significance? Statistical significance is a way to…
The Predictive Power of YOUR Data
Data, Data, Data… Over the past decade, almost every conversation I’ve had as it relates to food safety seems to revolve around data. The promise is always the same: if we just collect enough of it, we’ll uncover the answers to all our problems. And honestly, data can solve many challenges. But it’s equally important to recognize what data cannot do, and even more critical, to…

Beyond the Buzz: Rethinking AI (Artificial Intelligence)
When most people, including myself, think about Artificial Intelligence (AI), we tend to picture Chatbots like ChatGPT, Microsoft Copilot and other generative AI models that search the internet and generate human-like responses. While this is true, AI holds a far more practical role in day-to-day food safety. AI applications in food safety already extend beyond chat interfaces. They…

Data 101: Data Visualization
Data visualization sits at the heart of compelling data storytelling. Clear charts and thoughtfully designed figures are often the difference between insights that resonate with our audience or something that is just noise and gets no interests. As my PhD advisor reminded many times, the highest quality visualizations speak for themselves, they should be clear and intuitive that words are not…

Data 101: Understanding Summary Statistics: The Foundation of Data Analysis
Data analysis is the process of collecting, cleaning, analyzing and interpreting data. Before we get too technical into the different areas of data analysis, I want to introduce the concept of summary statistics. In data analysis, raw numbers alone often do not provide a clear picture of the underlying patterns or insights. It is important to understand how to summarize the raw numbers to start…
