March 27, 2007
Students were asked the following clicker question (Classroom Performance System, einstruction.com) near the beginning of their learning cycle:
[0.3 points.] The number of significant figures measures:
(A) accuracy.
(B) precision.
(C) determinacy.
(D) significancy.
For many students "accuracy" and "precision" are synonymous, but there is an important distinction between them!
Correct answer: (B).
Student responses
Sections 0906, 0907
(A) : 11 students
(B) : 15 students
(C) : 0 students
(D) : 2 students
N.B. This was the very first clicker question of the semester!
