## Advising for Mathematics and Statistics

This page provides an overview of our curriculum together with advice for students concerning placement in calculus and statistics.

#### Majors

- Mathematics: for students with an interest in pure and applied mathematics;
- Mathematics (statistics track): for students of mathematics wishing to focus their upper-level work in statistics;
- Mathematics-economics: for students interested in economics, the mathematical underpinnings of economic models, and mathematical and statistical methods as applied to economic problems;

See below for the exact major and minor requirements. See the Computer Science and Economics websites for information about those programs.

#### Calculus Placement

All three of the mathematics majors begin with the 3-term calculus sequence:

- MATH 140:
*Calculus* - MATH 155:
*Multivariable Calculus* - MATH 200:
*Complex Sequences & Series*

Here are some guidelines for placement (these apply to all students interested in calculus, not just prospective majors):

- All students intending to enroll in their first MATH course at Lawrence must take the ALEKS placement assessment covering topics in pre-calculus.
- Students scoring between 45 and 74 on the ALEKS exam should take MATH 103:
*Preparation for Calculus*. - Students scoring 75 or above on the ALEKS exam, and who have no calculus experience or who scored 3 or less on the AB or BC calculus exam should enroll in MATH 140.
- Students scoring 75 or above on the ALEKS exam, and who scored a 4 or 5 on the AB exam or a 4 or 5 on the BC exam should enroll in MATH 155.
- In general, students who score below a 45 on the ALEKS exam, or who are unsure of their level of preparation should consult with a member of the mathematics faculty regarding placement.

Most Natural and Social Science majors require at least one course in mathematics or statistics---students should consult the appropriate program requirements for details.

#### Statistics Placement

For students interested in statistics:

- Students
*without*prior study of statistics or calculus should enroll in STAT 107:*Principles of Statistics;* - Students
*with*prior study of statistics (e.g. AP statistics or BIOL 170) or credit for MATH 140 (or equivalent) should enroll in STAT 255:*Statistics for Data Science.*Students with credit for MATH 120 should consult with a member of the math department for placement advice.
