Office hours   The following hours are tentative - I'll finalize office hours after the 1st week
        M: 10-11am.   T: 10-11am.   W: 10-11am.    
And by appointment or walk-in. The best way to contact me, in order of preference, is: [1] in person,   [2] by email,   [3] by phone.
Open door policy: I keep my posted office hours to a bare minimum, to avoid being locked into a rigid schedule all semester. However, I am happy to assist students well beyond my office hours. Students are encouraged to just drop by whenever needed. Anytime my office door is open you're welcome to stop by and check whether I am available. Also, please do not hesitate to make an appointment if my posted office hours don't work for you.
Class website   https://cs.earlham.edu/~pardhan/courses/statistics/  
The website is a central component of this class, and you are responsible for regularly checking it for announcements, homework assignments and various supplementary handouts. I prepare for class with the assumption that students have reviewed the website and followed through on posted instructions.
A note of welcome  
It is my pleasure to welcome you to this class! Statistics is, hands down, among the most versatile and practically useful disciplines in the world. Whether you plan to be a scientist, economist, artist, entrepreneur, political activist, or homemaker, there is guaranteed to be a way for you to benefit from the use of statistical methods. You may well find that the skills you pick up in this class will be of value long after you graduate, in everyday life and in your profession.
A word of caution  
Many students take this course with misguided perceptions about how much time, effort and work it involves. Perhaps the course-title, with the word "Elementary" in it, is part of the culprit! To set the record straight, this class covers a vast range of materials, and is fairly challenging if a student doesn't devote adequate time to it. Please be advised that failure and dropout rates in this class tend to be high. For further details and individual guidance, students are welcome to visit the instructor.
Textbook  
Introductory statistics, by Barbara Illowsky, Susan Dean, and openstax.org.
Digital edition ISBN13 = 978-1-947172-05-0;   Paperback ISBN13 = 978-1-50669-823-6
Aditional supplementary material will be provided by the instructor for some topics.
Course credits  
This course is worth 3 credits, and will meet 3 times per week for 50-minute in-person classes.
Requirements this class fulfills  
Several Earlham majors and programs recommend or require students to take this class. These include: Biology, Biochemistry, Chemistry, Data Science, Exercise Science, Global Management, Neuroscience. In addition, this class fulfills the Quantitative Reasoning component of Earlham's General Education requirements.
Description & objectives  
The broad goal of this course is to introduce students to the foundational principles and practical methods of doing statistical analysis. More specifically, this course will teach you fundamental statistical concepts and techniques for organizing, analyzing, and interpreting data, as well as for other common statistical tasks such as correlation & regression, experimental design, probability, hypothesis testing and statistical inference. In addition, this course will introduce students to use the R software package for doing statistics. We will cover most topics in Chapters 1-12 of the textbook.
Student learning goals and outcomes  
Upon successful completion of this course, students will be able to  
  1. Organize, summarize and interpret data.
  2. Use technology tools to analyze data.
  3. Design and conduct a basic statistical research study.
  4. Understand fundamental probability concepts.
  5. Infer statistically valid conclusions using confidence intervals and hypothesis tests.
  6. Interpret and communicate the findings of their analyses.
  7. Strengthen logical reasoning, and quantitative skills.
  8. Use statistics to structure their understanding of the world around them, and to investigate interesting questions.
These aspirations broadly support all 5 learning goals of the Math Department, and the 7 goals of an Earlham education (see the Appendix attached to this Syllabus).

Course prerequisites  
High-school algebra, and a score of at least 50 on Earlham's Quantitative Skills Assessment (QANS).    
Assessment & grading policy 
In my approach to grading, correct process and method receive far more credit than correct answers. I always ask you to show all your work, and I grade all of your work!
Your final grade will be based on combined performance on: (1) quizzes, (2) two in-class exams, (3) a comprehensive final exam, (4) a term project, (5) homework problems, (6) classwork and labs. Each will contribute the following proportions:  
Quizzes 20%
Two in-class exams 15% + 15%
Final exam 15%
Homework 15%
Classwork and labs 20%

Letter grade boundaries for this course are not set in advance. They will be determined at the end of the semester based on factors such as overall class performance, level of difficulty of tests, quizzes, and assigned work, etc. At a minimum, the following standard scale for letter grades will be honored:
        A+: 97.0-100;   A: 93.0-96.9;   A-: 90.0-92.9;
        B+: 87.0-89.9;   B: 83.0-86.9;   B-: 80.0-82.9;
        C+: 77.0-79.9;   C: 73.0-76.9;   C-: 70.0-72.9;
        D+: 67.0-69.9;   D: 63.0-66.9;   D-: 60.0-62.9;   F: below 60.
NOTE that all students must also satisfy the following minimum requirements to receive a grade of C- or better:
        * Take at least 75% of the quizzes.
        * Take all the exams (2 during the semester, plus the final).
        * Turn in at least 75% of the homework, classwork and labs.
More details about assessment categories  
Quizzes:  There will be frequent short quizzes based on readings, homework, classwork and/or other assigned tasks. The primary purpose of quizzes is to encourage regular and timely engagement with the materials, and to provide continuous assessment of your work. The quizzes will help us accomplish most of the learning goals listed above.
Classwork and labs:  Classwork will be similar to doing homework problems, and will serve the purpose of hands on learning and practice in class. This will support all the learning goals listed above. The primary purpose of labs will be to learn how to do statistical analysis using the R software package. This will help us accomplish learning goals 1, 2 and 5, in particular.
Homework:  The purpose of homework problems is to build skills in the material. Exercises will be assigned from the textbook and other sources at various points throughout the semester. These must be turned in at the beginning of class on the indicated due dates. Homework exercises will help us accomplish most learning goals listed above.
Exams:  There will be two exams during the semester, plus a final exam at the end of the semester. The tentative dates of the mid-semester exams are:
  Exam 1: March 2.           Exam 2: April 13.

The final exam date and time is set by the registrar's office. According to their calendar, the final exam will be held Monday, May 16, in CST 103 at 8 am.
The final exam date and time is not negotiable. Please arrange any travel plans accordingly.  
Important dates  
      *   Last day to add this course: February 4.
      *   Last day to drop: April 15.
      *   Date of final exam: May 16.
NOTE: Last drop date applies to Earlham students only. Students cross-registered through IU-East or other institutions must follow the dates and rules of their own institution.
Academic integrity  
After several years of writing standard, boiler-plate stuff in this section, I have decided to replace it with a more authentic message from my heart to yours. Before getting into details, I would like to share 3 key ideas that profoundly shape my thinking, and prompt me to explore more effective ways towards academic integrity:
  1. Academic infractions are a much bigger problem at Earlham than many of us would like to believe or admit.
  2. The problem is NOT our students! Earlham students are as good (or better!) than their peers at other institutions in terms of moral values and ethical standards.
  3. Infractions at Earlham can be significantly reduced using a combination of strategies, collectively developed by students and faculty.
These three points summarize my overall perspective, and will frame the rest of my discussion on this subject.

By far the single biggest phenomenon that has radically transformed today's academic integrity / infraction landscape is technology -- particularly the internet and cell phones. In my view, Earlham's traditional approach to academic integrity has been rendered completely obsolete by these technologies. If I were an Earlham student today, I would encounter many situations where the temptation to infract would be extremely high, because these technologies make it so easy, and the risk of getting caught is virtually zero. This is the main reason why I say that you, the student, are not the problem. You are human, just like me and my faculty colleagues. It is a fact of life that many humans succumb to temptation when the rewards are sufficiently high, and the risks sufficiently low.

Yet, the fact remains, a growing rate of academic infractions is a terrible thing to ignore: They sink an institution's reputation, decrease the value of students' education, lower student & faculty morale, and more. Clearly, we need to explore and develop new strategies that are more effective for our times, and also preserve Earlham's distinctive approach to such matters. We will set aside some class time to discuss and formulate specific policies for helping students (joyfully!) meet and exceed the highest standards of integrity in this class. In the meantime, I invite you to reflect on some practical ways that would most help and support you in avoiding the use of inappropriate sources for completing and turning in your graded work.

I would like to conclude with the following excerpt from the Earlham Academic Integrity Policy:
"The College trusts students who enroll at Earlham to be honest seekers of truth and knowledge. This trust is extended to all students by other students and by teachers ...   Giving or receiving aid inappropriately on assignments and tests, or plagiarizing by using another person's words or ideas without credit, constitutes a serious breach of our trust in one another and in the integrity of the search for truth. Those who believe they have witnessed violations of academic integrity should feel the obligation to speak about this to the suspected offender. The witness also should feel obligated to report the suspected offender to the instructor if the person fails to offer a satisfactory explanation and refuses to report him or herself. ...   Violations of academic integrity, because they undermine our trust in one another and in the credibility of the academic enterprise, are taken very seriously. Penalties for violations range from failing assignments or tests to suspension or expulsion from the College. "

Makeups  
In-class items: There will be no makeup for missed in-class items (e.g., quizzes, classwork, class participation, etc.) regardless of reason. I will drop your lowest two scores as an implicit way of making up for missed items.
Homework: Past-due assignments will not be accepted except in rare circumstances, provided the student receives prior consent from the instructor.
Exams: Make-up exams will not be given except in cases of documented illness or emergency.

Academic accommodations
Students with a documented disability (e.g., physical, learning, psychiatric, visual, hearing, etc.) who need to arrange reasonable classroom accommodations must request accommodation memos from the Academic Enrichment Center (main floor of Lilly Library) and contact their instructors each semester. For greater success, students are strongly encouraged to visit the Academic Enrichment Center within the first two weeks of each semester to begin the process. For further details, please visit
