Which APA Style Rules Are the Most Challenging to Learn?
Many of you are probably wondering what error reached Number 1 in our Top 60 list. Great question! Well, the most common APA Style error is the incorrect use of numbers. Even though we examined manuscripts written by authors who used the fifth edition of the APA Publication Manual (because the sixth edition of the APA manual is so new), all of the APA Style rules violated still apply in the sixth edition.
Falling into this category are (a) numbers expressed in numerals (APA, 2010, section 4.31), (b) numbers expressed in words (section 4.32), and (c) combining numerals and words to express numbers (section 4.33; see pp. 111–112).
