 Amsco Integrated Algebra I: Collecting Data
This is a free lesson from our course in Amsco's Integrated Algebra
 
   
This lesson covers statistics including some basic concepts of collecting data. Statistics is devoted to the collection, compilation, display, and interpretation of numerical data. The first step in doing a statistical study is usually to collect data selecting a representative sample. In a statistical study, data is collected, organized into tables or graphs, and analyzed to draw conclusions. Data can be qualitative or quantative. Quantitative data represents counts or measurements. Qualitative data represents categories or qualities. Data can be collected through written questionaires, an interview either in person or telephone, a log or diary etc. (More text below video...)

(Continued from above) But it may not always be possible to find information about every person, object or situation so sampling is used. But the sampling must be fair or unbaised and must contain a reasonableness of items being tested or counted. For example: to determine which television programs are the most popular in a large city, to select/interview sample or cross section of people at random without bias (from the possible choices- a ball park, a concert hall, a supermarket), would probably be found outside a supermarket. The video above will explain in detail with the help of several examples.

 
   

As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Trigonometry by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
