Learning Outcome 5:The learner will be able to collect, summarise, display and critically analyse data in order to draw conclusions and make predictions, and to interpret and determine chance variation.
Assessment Standard 5.1:We know this when the learner poses questions relating to human rights, social, economic, environmental and political issues in own environment;
Assessment Standard 5.2:We know this when the learner selects appropriate sources for the collection of data (including peers, family, newspapers, books, magazines);
Assessment Standard 5.3:We know this when the learner uses simple questions (with a variety of possible responses) and designs and uses questionnaires (with yes/no type responses) in order to collect data (alone and/or as a member of a group or team) to answer questions;
Assessment Standard 5.6:We know this when the learner identifies the largest and smallest scores in a data set and determines the difference between them in order to determine the spread of the data (range);
Assessment Standard 5.9:We know this when the learner summarises ungrouped numerical data by determining mean, median and mode as measures of central tendency and distinguishes between them.
