The amount of information that a student must read and comprehend is enormous. Much of it is presented in some quantitative manner (data tables, graphs, or figures, for example.) Using the data in an article, students may discover some dimension of quantitative literacy such as: patterns, trends, scale, proportion, probability, and statistics.
We offer a few basic questions below to help students focus on the purpose of the data in the articles. However, if you or your students have a need to examine in detail, various aspects of probability and statistics, then visit Virtual Laboratories in Probability and Statistics. This site provides introductions to the basic topics and excellent experiments that demonstrate probability.
Equations
- What does each symbol represent?
- What is the relationship between the variables?
- Can you verbally express the relationship that is being described?
- If you increase one variable, what happens to each of the other variables in the equation?
Graphs
- What is the title of this graph?
- What is being described?
- What are the variables being graphed?
- Are the increments on each axis of equal value?
- Do the units of each axis make sense for the variable being described?
- What is the relationship between the variables?
- Is there any bias in the graphing, e.g. extending or compressing information on an axis to change the perception of the relationship?
