Subject Title

Subject Description
This course provides an introduction to basic statistical concepts and techniques that are common to various disciplines.  Statistical methods of data collection, analysis, presentation and interpretation for making generalizations, projections and decisions will be introduced.  Both descriptive and inferential techniques will be explored.  

Credit Status
Required mathematics course for students in the Bachelor of Interdisciplinary Studies degree program

Learning Outcomes
Upon successful completion of this subject the student will be able to:

  • Demonstrate the ability to present, describe and summarize data using graphic representations, measures of central tendency and variation.
  • Evaluate probabilities by defining sample spaces and through the use of probability rules, including mutually exclusive and independent cases.
  • Distinguish between discrete and continuous random variables and determine expected value and standard deviation of a discrete random variable and binomial probability distribution.
  • Determine the probability of intervals on a normal distribution using z-scores and a normal distribution table.
  • Calculate the mean and standard error of a random variable and probabilities for a given sample mean using the Central Limit Theorem.
  • Use sample data to determine confidence intervals for the mean and proportion of populations.
  • Construct a test of hypothesis of a mean or proportion by indicating the null and alternative hypothesis, identifying and calculating the test statistic, and drawing appropriate conclusions.
  • Perform simple regression and correlation analysis by determining and interpreting the correlation coefficient, the coefficient of determination and the coefficients of the sample regression line.
  • Use a regression equation to predict the value of the dependent variable for a selected value of the independent variable and conduct a test of hypothesis for the coefficient of correlation and each coefficient of regression.
  • Determine and interpret confidence intervals and prediction intervals for the dependent variable.

Essential Employability Skills
Execute mathematical operations accurately.

Apply a systematic approach to solve problems.

Use a variety of thinking skills to anticipate and solve problems.

Manage the use of time and other resources to complete projects.

Take responsibility for one's own actions, decisions, and consequences.

Modes of Evaluation
Term Work

All term work assignments must be completed prior to the time of the final exam or last class.  Students must contact faculty in advance of the assignment due date to discuss the possibility of an extension.  Late assignments may be subject to the awarding of a penalty resulting in a lower grade assigned. Make-up opportunities for assignments must also be made in advance of the scheduled due date.  If an assignment is missed due to class absence, official documentation must be submitted to the faculty member on or before the next scheduled class. Make-up opportunities may not apply to all graded assignments.


Classroom   Online  
Tests (x2) 20%       Discussion Posts (x3) 30%    
Mid-Term Exam 20% Interactive Exercises (x3) 30%
Assignments 35% Major Data Project 40%
Final Exam                       25%    

To be successful in this course, you must complete all course work as specified, and achieve an overall grade of 50% or more.  It is expected that students have a sufficient command of the English language to express themselves clearly in both written assignments and class discussions. For further information on evaluation and academic standing, see the Academic Policy at

For online delivery: All Seneca College academic policies apply. This includes, but is not limited to policies related to grading, supplemental exams, deferred exams and accommodations.  Students must achieve a final grade of 50% in order to pass the course.
