Conditional Probability

Published / by William

Sorry that it’s been a little while since my last post, I was away on vacation for a couple of weeks. While away, I caught up with an old college friend. He’s the owner of West Hartford Roofing Services in West Hartford, Connecticut. While reminiscing of college years, we talked about the statistics class we took together, and both struggled with together. We were talking about how most of what we learned in college has been forgotten, and that most of what we do remember is pretty much useless to us today. And that is the segway into today’s topic of conditional probability. To this day, we still both remember the concepts of conditional probability, but we’re not quite sure if it’s been of much use since the day we finished that class.

As many of you know, conditional probability is used to determine the probability that an event (B) will occur, given that an event (A) has already occurred. Seems simple enough, but it can get confusing. I found this video on YouTube for anyone that is looking for some helpful guidance with understanding the concepts. Enjoy!!

Analyzing Satisfaction Survey Data

Soooo, I never had to analyze satisfaction survey date while in school or in my career thus far. However, I came across this YouTube video on the subject, particularly as it refers to analyzing the data in excel. I found the video to be interesting and I’m sure it will help some of you. If you would like to view this video on YouTube, please click here. Enjoy!!!

Likert Scale

Here’s another good video I found that discusses the Likert Scale and how to analyze questionnaire data. If you’re looking for some information about the Likert Scale in general, here’s a link the Wikipedia page on it; it full of useful information.

I hope you enjoy this video…let me know your thoughts…

Here’s a link to the video on YouTube.

Back to the Basics

I hope you enjoyed yesterday’s post on analysis of variance (ANOVA).

In retrospect, my first post on this subject probably should’ve started with something a bit more basic to help build more of a foundation on statistical analysis. Today, I’d like to share a video I found that provides an introduction to statistics, particularly levels of measurement.

This video can also be found on YouTube by clicking here.

As I mentioned in the “About Me” page, I found several concepts difficult to grasp while in college. One in particular is Analysis of Variance (ANOVA). Here’a video I found on YouTube that is pretty useful.
