Dr Nic goes to ICOTS9

I had a great time at ICOTS9. Academic conferences are a bit of a lottery, but ICOTS is two for two for me. Both ICOTS8 and ICOTS9 were winners – enjoyable, interesting and inspiring.  I’ve just returned from ICOTS9 in Flagstaff, Arizona, several kg heavier, with lots of ideas for teaching and our videos, and feeling supported in the work I am doing on this blog, and with our resources and videos. I have met smart, good people who are genuinely trying to make things better in the world, by helping people learn about statistics. Most times when I go to […]

The Golden Rule doesn't apply to teaching

Problems with the Golden Rule The Golden rule is fundamental to most human cultures.

Not long after after we were married, my husband was lying sick […]

Techniques, concepts and attitudes interact in how a student learns and perceives the subject. Sadly it is possible (and not uncommon) for students to master techniques, while staying oblivious to many of the concepts, and with an attitude of resignation or even antipathy towards the discipline. Techniques Often, and less […]

Lies and statistics

One of the most famous sayings about statistics is the line: “There are three types of lies, lies, damned lies and statistics.” This was stated by author Mark Twain (Samuel Clements)  and quoted by British statesman Benjamin Disraeli.  There is a book entitled, “How to lie with statistics”. Within high school education students are taught about misleading graphs. It seems clear that statistics and facts are not the same thing. Yet one True/False question many of my students continue to get wrong says “Statistical analysis is an objective science, unaffected by the researcher’s opinions.” The correct response is False, yet […]
