So now we will need to teach students how to read pre-2009 vs
post-2009 indexes of variability. Students are going to enjoy

I just noticed that the APA now indicates that “/s/” should
be used for the “Sample standard deviation (denominator SQRT(/n/ – 1),
while “/SD/” should be used for <population, denominator SQRT(/n/)>
“Standard deviation. The addition of “/s/” to the table of statistical
abbreviations and symbols is new to the sixth edition. Since it is the
statistic rather than the parameter that we almost always report, I
expect that “/SD/” will pretty much disappear from the future literature.
