Delete: On page 217, in the course
description for STAT 225:
Prerequisite: MATH 192.
Add: On page 217, in place of deleted
entry:
Prerequisite:
MATH 191
Impact:
Enrollment in STAT 225 may increase, but need for
additional sections are not anticipated.
Rationale:
The original
rationale for requiring the second semester calculus class as a prerequisite
for these courses was that students needed to be exposed to exponential
functions and improper integrals. Both of these topics are now routinely
covered in the first semester of calculus. In one topic of STAT 225, the study
of distributions and their means, there may be examples that require knowledge
of MATH 192 material. Specifically, these are the integration technique,
“integrating by parts” and the rules for convergence for an infinite series.
These examples are not essential to the course and if an instructor wishes to
include them they can still be discussed by giving a short explanation of the
necessary methodology / theory within the class.
The benefit of reducing the prerequisite is to
encourage students to take this class earlier in their studies. Statistics is essential for many upper level
classes both within and outside the department. Allowing students to take this
statistics immediately after MATH 191 means students can take STAT 225 in their
freshman year.
STAT 220 is designed to help students who already
took STAT 185 but are required to take STAT 225 to complete major requirements.
STAT 220 covers those topics that are in STAT 225 but not in STAT 185. Thus any change in STAT 225 must also be
carried over to STAT 220.
