Survey follow-up: Breakdown by region

Let me see, I'm fairly confident that nothing bad has ever come from comparing one country against another, right?  Good, then I feel completely comfortable reporting on this geographical comparison from the PD survey results, as some have asked me for.  I'll highlight only those comparisons in which there were significant differences in the mean rankings between the US (n = 67), Canada (n = 57) and the UK (n = 65).  There were not enough respondents from the other regions to allow meaningful statistical comparisons.  The results below are the results of one-way ANOVA with 'region' as the between-groups variable and mean ranking (where a higher number is rated as more preferable/important) as the dependent variable.  Significant main effects were further explored using Tukey's post-hoc test.  One caution though, with this many comparisons being done it is entirely possible some of these results were significant by chance (that's an alpha error, for those that remember their stats courses).  With that said...

The US and Canada respondents ranked 1-2 day in-person courses significantly more preferable than the UK respondents (US = 1.6/7, Canada = 1.3/7, UK = 2.5/7)

The UK (3.5/7) respondents indicated they were significantly more likely to participate in  'reading scientific literature' than the US (4.4/7) and Canada (4.9/7) groups.

The UK (3.9/7) respondents indicated they were significantly more likely to participate in  'reading summaries of scientific literature and answering comprehension questions' than the US respondents (4.6/7).

The US respondents (5.9/7) ranked an instructor's social media presence as significantly more valuable than either the Canada (6.7/7) or UK (6.4/7) groups.

The UK respondents ranked the instructors global reputation as significantly more important than the Canada respondents (3.7 vs. 4.4/7).

The Canadian respondents ranked 'receiving a certificate upon course completion' as significantly more important than the UK respondents (7.1 vs. 7.8/10)

The UK respondents ranked 'the course materials clearly show the information is supported by scientific evidence' as significantly more important than the US respondents (3.9 vs. 4.6/10)

The UK respondents ranked 'distance you have to travel' as significantly more influential on their PD decisions than the US respondents (2.2 vs. 2.8/7).

The UK (6.1/7) ranked 'the amount of additional materials you have to purchase' as significantly less influential on their PD decisions than either of the Canada (5.1/7) or US (5.2/7) groups.

There you have it, those are the only items on which there were any statistical differences in mean importance/preference rank between the regions.  For the record, the item asking respondents to choose their preference between a 2-day live in-person course or equivalent 2-day online course at half the price of the in-person course did not show a significant difference in proportion of responses via chi square test (US: 82.1% favor in person, Canada 77.6% favor in person, UK 75.4% favor in person).

I'm just glad we weren't comparing hockey or soccer superiority between regions.  That would have been professional suicide.
