Scope of Course:

This is a calculus-based probability and statistics course for upper division undergraduate students. The main goal of this course is to provide various statistical methodologies and their applications in data analysis. We will explore Chapter 1 through Chapter 10 in the text at minimum and some selected topics from chapters 11- 12 if time permitted. Among topics to be covered will be


1.       Data, Graphical Descriptive Techniques - Measures of central Tendency and dispersion; numerical measures of relative standing; box plots, outliers, scatter-plots.

2.       Introduction to probability - Sample spaces, events, probability rules; conditional probability, independent events. Bayes theorem.

3.       Random variables and their distributions - Discrete random variables; probability distributions, binomial and Poisson distributions, continuous probability distributions, Normal and exponential distributions, Joint probability distributions, Expectations of random variables.

4.       Sampling distributions - Sampling, law of large numbers, central limit theorem.

5.       Estimation - Point estimation, desirable properties, confidence interval for a population mean and a population proportion; sample size determination.

6.       Testing Statistical Hypotheses - test of hypothesis about a population mean: z-test; t-test, p-value; test of hypothesis about a population proportion, comparing two population means: independent sampling and paired t-test. Chi-square test for categorical/frequency data.


Homework, Quiz & Worksheet: There will be weekly homework assignments given in class and expected to complete them by the following week. Some of them will be collected for credit. Quizzes/worksheet will be given for credit and for practice. Late submission will not be accepted unless arranged with the instructor in advance.


Grading: The course grade is evaluated based upon the following components: Homework & assignments - 20%, Two tests (in class) - 25% each, Final Exam - 30%.


Exams: There will be two midterm exams most likely on 6th and 11th week. The final exam is scheduled according to the university calendars and schedules.
