Unit 7

Data Analysis and Probability

"In this unit, students will examine and create many types of graphs that are common to data management: circle graphs, bar graphs, pictographs, line graphs and double bar graphs. They will make informed decisions about which graph best represents a data set and also learn how to support that decision. In many cases one type of graph is better than another when representing a data set, and provides a visual image that is more informative and useful. Students will differentiate between graphs that are accurate and graphs that are misleading. They will also learn to recognize the false conclusions that misleading graphs try to represent. They will study the basic principles of probability as it pertains to

single events, independent events, and more than one independent event occurring simultaneously or in sequence. These principles will be applied to problem solving situations. Statistics are used to measure a nation’s economic performance and help governments make informed decisions about budgets, social programs, population issues and health care. It is a branch of mathematics that assists with tracking such things as inflation, the efficacy of medicines, and the performance of athletes, as well as predicting weather patterns." - Grade 8 Curriculum Guide
