Hello students, 

          Welcome to College of the Canyons Mathematics 140: Introductory Statistics. My name is Udani Ranasinghe and I will be teaching this course. I have been teaching Statistics for over 10 years at different community colleges and universities. Currently, I am teaching at COC.

I like to do Sudoku puzzles, watch sports and read in my free time. I love to dance and travel. 

I am very excited to meet and get to know you all. See you soon. 

Course Description

This course is very well structured. You will find everything in your canvas shell. This class is very different from regular math classes where you do certain type of problems and have one answer. This course is analysis based where we analyze data and do meaningful calculations with the help of computer software. Then afterwards, we will interpret those calculations in sentences and focus more on conceptual knowledge rather than calculations. You will have reading and writing assignments like an English class. So, this is not your typical math class.

We will cover Data analysis, Quantitative and Categorical variables, Sampling techniques, Sampling distributions, Confidence interval, Hypothesis testing, etc.

What to Expect in this Course

We will have online class meetings using Zoom during our class time. The goal of our weekly meetings is to use our time together to accomplish tasks that may be more difficult to complete on your own. Of primary importance is to build and strengthen our class community. Learning can be more enjoyable and efficient when we learn together! 


***Your weekly time commitment for Math 140 is around 10 hours in addition to the class meetings.
