Teaching Tools | Web Apps

-

Hello! Here's a list of my current web apps with fun tools for teaching topics such as histograms, normal distribution, mean shift and spread, scatter plots, and boxplots. I continue to work on more fun apps that will support the Lean Six Sigma practitioner and other teachers alike in their content delivery.

I hope you'll enjoy the experience! Click on the titles to open the apps.

The Mathematical Significance of Wisdom Over Time

-

My oldest daughter Maya turned 15 yesterday, Aug 21, 2022. I took some time and went to see her at the end of her special day. Amongst other things, we were discussing wisdom, and how we mature over time. Indeed, a natural process for all of us. I was telling Maya that as she grows older, she will learn things. She will learn things in school, and she will learn things in life. Perhaps more in life than in school. Then we caught ourselves discussing a more numerical type of analysis (Maya has always been amazing with numbers). We realized that, when she was at her year zero (of course, this is a figure of speech) I was 30. She was a baby whom only knew how to cry for food while I knew a little bit about life and things. Now she is 15, she knows a little bit more than what she knew when she was 0, or 5, or 10. I'm 45, I also know a little bit more than what I knew when I was 30 (or 0, or 5, or 10). We decided to graph the data, looking into the "wisdom rate of growth" over...

Binary Logistic Regression for Raccoon Visits to My Backyard

It's that time of the year! No, I don't mean April showers bring May flowers, I mean the time when our fellow wild life animals like to visit our backyards often in search for food. Our raccoon friends have become a bit of an annoyance though since they like to sometimes use our deck as latrine. So, I've been collecting some data and have decided to run a binary logistic regression with the help of SigmaXL statistical package to predict the probability that these masked bandits may (or may not) show up. For that, I've been using a safe and natural repellent (I won't broadcast but, it's coyote urine) to help me in discouraging the presence of the poopy animals around our property. The Data Here's a snapshot of the data I've been collecting. As you can see, the outcome (Y: Raccoon Appearance) expected is a binary (dichotomous) variable. I'm trying to figure out if Mr. Coon and friends will show up or not given certain predictors. I've been trackin...

Gage R & R Full Example with ProcessMA

-
Image
Gage R&R (Repeatability & Reproducibility) is a Measurement Systems Analysis (MSA) technique that uses ANOVA to assess the accuracy of measurements given variation found in parts and operators measuring parts. We start by looking into the setup of the example. The data contains: Three operators: 1, 2, and 3. Three trials: 1, 2, and 3. Ten parts: 1 through 10. This means 90 responses: each operator measures each part 3 times (3 operators x 10 parts x 3 times = 90 responses). Here's a snapshot of the dataset (first 30 rows): To perform a Gage R&R in ProcessMA, select GageRnR (Crossed) under the option Gage RnR  as shown in the screenshot below. The following fields should be selected accordingly for the study: Study variation: 6 * the standard deviations of each source of variation Hit OK. The first table of results showcases the ANOVA output. Recall from the ANOVA significance tests that we are looking into two or more factors and their interactions; in this example: pa...
