Many scientific studies are full of statistical jargon, tables of averages and other statistics, and results of statistical tests which purport to prove a certain hypothesis. The purpose of this course was to review some of the basic sampling and experiment designs used by ecologists and to understand exactly what can and cannot be extracted from a set of data. With the advent of modern statistical packages, the analysis of data is fairly easy, but it is far too easy to get nonsense results. This course also reviewed common pitfalls in the analysis of data.
Prerequisites: A “basic” knowledge of statistics, i.e., usually a single course somewhere in your background. A working knowledge of “R” software. If you are new to “R” then we have a 1/2 day Intro to “R” Software course taking place the day before this course! See HERE for more details.

Preparation for the course
About 2 weeks before the course you will be sent a web link where you can download pre-reading, a course manual, a set of practice exercises to load on your computer before the class, and instructions on where and how to get the course software.
You will need to bring your own laptop pre-loaded with the required software and downloaded files.
Consider bringing along an external monitor and an external keyboard if you have a small laptop.
You will need to make your own hotel booking, and remember to ask for the rates we’ve arranged for people attending this course (see below).
** The course starts at 8:30 a.m. sharp, you will need to arrive before that so you can set up your computer.
Registration includes catered breaks provided by La Baguette and there is an option to add in bagged lunches for $13/day. Registration for the preceding half-day Introduction to R software course may be done at the same time as registration for this course (see link below).
CMI Member: $675.00*
*NOTE: You can purchase your $40 membership at the same time as you register. See more about membership here.
Where to stay?
We have set up a room-block at the Stoke Hotel with a special room rate of $89.99 + tax / night, includes continental breakfast, and new outdoor hot tub. Rooms held until XXX 2019 after which they will be available on first come first serve basis. To receive this rate you must call the hotel directly at 1-877-837-5221 and state that you are with the “CMI group.” This hotel is located across on the west side of the highway but is still an easy walking distance to the college. Ask them to direct you to the river-side path that will take you under the highway bridge.
If you are wanting to camp, we recommend the Lamplighter Campground which would only be about 10-15 mins walk from the college. This campground is well-maintained and has all the amenities. 250-837-3385.
