An enriching experience
On-line learning is a dynamic experience. Throughout the course, you will engage in "dialogue" with an "intelligent" site that will respond to your input with immediate explanations and feedback.
You will acquire new knowledge, not only by reading pages on the Web site, but also by interacting with images, animations, sound recordings and Internet resources.

Statistics II Course Overview
Statistics II (MTH-4104-2) is the second of a series of three courses on statistics and it is compulsory in the mathematics program of study in basic general adult education.
You must pass an examination administered by a school board in Québec in order to obtain an equivalency for 416, 426 or 436 courses (Secondary IV) in the youth sector.
The recommended duration of Statistics II is 50 hours.

Course objectives
- To identify the characteristics of different methods of gathering data for a statistical survey.
- Justify the choice of method used (census, sample survey, study) to collect the information needed to conduct a statistical survey.
- Demonstrate whether a sample is representative in the case of a sample survey whose characteristics (target population, expected reliability, etc.) are described.
- Interpret the results of a sample survey taking into account the margin of error and the distribution of the undecided respondents.
- Identify sources of bias that may affect the conclusions of a statistical survey.
- To interpret measures of central tendency, measures of dispersion and measures of position relating to a concrete situation
- Solve word problems involving measures of central tendency (mean, median, mode) and of dispersion (range).
- In a distribution related to a concrete situation that is clearly defined, assign a quintile rank or a percentile rank to a particular data value. Determine the data value that corresponds to a given percentile rank in a distribution.
- Given a distribution that corresponds to a clearly defined concrete situation, construct a box-and-whisker plot and determine the various statistical measures that can be derived from it.
- Interpret the box-and-whisker plot for a distribution corresponding to a concrete situation that is clearly defined.
- To analyze graphic representations of distributions.
- Compare distributions represented by graphs.
