When learning statistics, one of the most fundamental yet usually grossed over concepts is that of **variance** (i.e. the square of the standard deviation in normal distribution). As we know, virtually all statistical operations which measure deviations of individual values from the norm involve adding the **SQUARED differences between the two numbers**. However, very few instructors could explain why we have to use squares rather than just the absolute values of the difference (or other even powers such as 4, if the intention is to avoid the negatives). This tutorial shall cover this in a convincing manner. Secondly, while we all know the variance of a SAMPLE is arrived by dividing (n-1) of the sum of squared differences, where n is the number of observations, few can articulate the rationale behind it. This tutorial shall also prove step by step why this is case, so after this you could appreciate the logic behind this ingenious insight instead of just reciting it like a medieval myth.

Tuesday, June 2nd, 5:00–8:30 PM Eastern Central Ohio Chapter Meeting IN PERSON IN COLUMBUS How I Get Private Lenders and Partners to Fund My Deals If you can’t fund it, you don’t have a deal. And right now, funding is where more investors are getting stuck. Private lenders are more cautious. Partners are asking better questions. And deals that look good on paper still fall apart when the money doesn’t show up. That’s why we’re bringing in a panel of investors who are actually getting their deals funded right now. You’ll hear how they’re finding money, structuring deals, and building relationships that lead to repeat funding. Here’s what you’ll learn: * Where they’re finding private lenders today * How they start conversations that lead to funding * What makes lenders and partners say YES * How they structure deals to be fundable * The biggest mistakes investors make when raising money * How to build repeat funding relationships **Early Session (6:00–7:00 PM Eastern):** **Having Trouble Finding Tenants? How Community Shelter Board Can Help** Nicholas Brenner will walk you through programs designed to help rapidly rehouse tenants, including financial support that can stabilize your rentals. **The Deal Room (7:00–7:30 PM Eastern)** Bring deals, funding needs, buyers, and problems. This is where connections turn into action. This meeting is for serious real estate investors nationwide, and we’re known for our high-content, real-life education and our nationwide community of dealmakers. Members and non-members at all levels are welcome. Register below to reserve your seat.

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
