Back in January I shared my favorite way to average plot data in R, but some of my lab mates don't use R and are looking for an alternative. They keep averaging their plot data by highlighting 10 cells at a time and using the AVERAGE function, which is rather inefficient and introduces human error.… Continue reading Averaging Plot Data in Excel

Averaging Plot Data in R
In agronomy research, its very common to collect 10 plants from a single plot, take measurements on them, and average those measurements. The plot average is the value we run statistics on, whether that means building a regression or running an ANOVA. I've recently seen a lot of my fellow grad students averaging measurements by… Continue reading Averaging Plot Data in R
Random Forest
Machine learning algorithms are cool because the can handle continuous and categorical variables and have few assumptions about data distribution. As the name machine learning would imply, it's a highly automated process. Sometimes they take a while to compute, but the computer can be unsupervised during that time. One machine learning algorithm I use in… Continue reading Random Forest
Basic Statistics Fact Sheet
This might be an older fact sheet (originally published in 2008), but it's still an incredibly helpful guide: Highlighted Fact Sheet I like it for a few reasons. Firstly, it's written in plain English. There's not a single equation in it, and the whole paper is only 3 pages. Secondly, and probably more importantly, it… Continue reading Basic Statistics Fact Sheet
