Data Handling and Probability

In Grade 2, students develop their skills in collecting, organizing, representing, and interpreting data. They learn to create and analyze various types of graphs and begin to understand basic concepts of probability through everyday experiences.

Grade Two Expectations for Data Handling and Probability

Essential Learning Outcome 1: Developing Statistical Literacy

Recognize topics for investigation and formulate questions with no more than four option choices
Collect, organize data with no more than two attributes
Record and display data in tables as tallies and pictographs
Identify the most frequent count, if any, for various data sets presented in concrete graphs, pictographs, bar graphs, and tables
Explain what this measure indicates about the data
Analyze different sets of data presented in various ways, including in logic diagrams, line plots, and bar graphs
Ask and answer questions about the data and draw conclusions
Make convincing arguments and informed decisions based on data

Specific Curriculum Outcomes

By the end of Grade Two, the learner will be expected to:

Teacher Content Knowledge

Data is gathered information - especially facts or numbers- that can be used to find out things or to make decisions when examined. Data handling is the process of gathering, recording, and presenting the data or information in a way that is meaningful to others. Good questions are an integral part of data collection. As well, data collection provides a way to connect mathematics to other subject areas. The data collected can then be analysed to make data-driven decisions in the real world. Probability is an essential tool in applied mathematics and mathematical modelling. It is also an essential tool in statistics. A probability describes mathematically how likely it is that something will happen.
