Unit 7

Data Analysis

"The three measures of central tendency are mean, median and mode. In this unit, students will examine sets of data to determine the measures of central tendency. Each one of these is a way to describe a set of data with a single meaningful number. In some situations, only one of the averages makes sense, but in other situations, two or three averages are meaningful, even if they are different. Students will determine which measure is the best representative of a given data set. The presence and effects of outliers will be considered. Following data analysis, students will work with probability. These topics are examined together because it is through collecting, organizing, representing, and analyzing data that students are able to draw conclusions about probability. Using tree diagrams and tables, students will develop sample spaces for events, and then determine the probability of two independent events. They will compare theoretical probabilities with experimentally determined probabilities, and see that as the number of trials in an experiment increases the experimental probability of an event occurring gets closer to the theoretical probability of that event occurring." - Grade 7 Curriculum Guide
