I finally understand RCBD!

But sadly, it's 2.42pm here, which is 2.42am in Singapore, and the BlueTempeh is offline, so there's no-one I can share my nerdy joy with...

So some reason, the textbook and various explanations on the web all assume that you can automatically see what the big advantage of blocking is (RCBD is randomised complete block design for you non-stats heads out there), and it was so frustrating to do the analyses without seeing the big picture. Had to revisit the model equation, the SS equations and the math again and again before I finally worked it out...pooooh!

So okay, I can see why one might want to block treatments, but the assumption of no interactions is a little niggling. Hm. Will have to ponder some more.

At first we thought it would be the quickest way, but we went all over Manhattan dropping people off at various hotels and hostels, so it was almost 10am by the time we checked in at Harlem YMCA. Not too bad, except that there was no a/c and NY was experiencing a heatwave!! It was sweltering in the small room. Washed up a little and proceeded to our first destination... The Empire State Building! Well, that's the view from the top. For some reason I don't seem to have a photo of the building itself. Think I was jetlagged and starting to get mild heatstroke....Y...

Does this mean something?

Something struck me while I was preparing tomorrow's lesson plans for Genetics lab and thinking up wicked questions for next week's quiz for my students.. (well, not really, I'm actually a softie at heart who wants her students to do well, hahaha...). For someone who always professed to having a mild phobia to teaching, I've been doing a lot of teaching in the last 6-7 years or so! It started with being a nature guide talking to all those strangers about wildlife and conservation, to conducting sessions on how to be a nature guide, and all those courses on Reef Check and whatnot, plus instructing for educational companies like Creative Kids, where I had to teach primary and secondary students, all the way to trainee teachers and full-time teachers! Recently have also been teaching at NUS and here in Wilmington! I had a 'what are you planning to do with your life after you graduate' talk with my current supervisor recently, and mentioned that I don't really s...
