Math K - 7 IRP Statistics and Probability (Data Analysis)

Students collect, display, and analyse data to make predictions about a population.

It is expected that students will:

Grades K to 1 Grades 2 to 3 Grade 4
Collect, organize, and analyse (with assistance) data based on first-hand information

Collect data based on first- and second-hand information, display results in more than one way, interpret data, and make predictions

Collect first- and second-hand data, assess and validate the data-collection process, and graph the data



  • collect first-hand information by counting objects, conducting surveys, measuring, and performing simple experiments

  • sort objects to one attribute chosen by themselves or the teacher

  • construct a pictograph using one-to-one correspondence

  • compare data using appropriate language, including quantitative terms

  • pose oral questions in relation to the data gathered


  • formulate questions and categories for data collection and actively collect first-hand information

  • use a variety of methods to collect and record data, including measuring devices, printed resources, and tallies

  • sort and organize data by one or more attributes and by using graphic organizers such as lists and charts

  • identify attributes and rules in pre-sorted sets

  • display data in more than one way, including graphs, pictographs, bar graphs, and rank ordering

  • discuss data, communicate conclusions, and make predictions and inferences to solve similar problems

  • generate new questions from displayed data

  • obtain new information by performing arithmetic operations on the data


  • select an appropriate sample or population and organize the collection of data

  • manipulate data to create an interval graph/table for display purposes

  • construct a bar graph and a pictograph using many-to-one correspondence and justify the choice of intervals and correspondence used

  • evaluate the process by which the data was collected


It is expected that students will:

Grade 5 Grade 6 Grade 7
Develop and implement a plan for the collection, display, and analysis of data gathered from appropriate samples Develop and implement a plan for the collection, display, and analysis of data gathered from appropriate samples

Develop and implement a plan for the collection, display, and analysis of data, using measures of variability and central tendency

  • identify a question to generate appropriate data and predict results
  • distinguish between a total population and a sample
  • use a variety of methods to collect and record data
  • create classifications and ranges for grouping data
  • display data by hand or by computer in a variety of ways, including:
    • frequency diagrams
    • line plots
    • broken-line graphs
  • evaluate the graphic presentation of the data to ensure the clear representation of the results
  • discuss the reasonableness of the data and the results
  • make inferences from the data to generate a conclusion
  • formulate a key question from a problem-solving context
  • identify appropriate data sources (first-hand, second-hand, a combination of first- and second-hand)
  • select and justify appropriate methods of collecting data (designing and using structured questionnaires, experiments, observations, and electronic networks)
  • select and justify the choice of an appropriate population sample to use to answer a particular question
  • discuss how the data collected are affected by the nature of the sample, the method of collection, the sample size, and biases
  • display data by hand or by computer in a variety of ways, including histograms, double bar graphs, and stem and leaf plots
  • read and interpret graphs that are provided
  • describe the general distribution of data:
    • smallest and largest value
    • frequency (which occurs most often/least often)
    • value in the middle
    • patterns
  • analyse sets of data to make comparisons and test predictions
  • formulate questions that explore whether or not a relationship exists in a real- world context
  • select and justify appropriate methods of collecting data (designing and using questionnaires, interviews, experiments, and research)
  • display data by hand or by computer in a variety of ways, including circle graphs
  • read and interpret graphs that are provided
  • determine measures of central tendency for a set of data:
    • mode
    • median
    • mean
  • determine measures of the distribution of a set of data:
    • range
    • extremes, gaps, andclusters
    • quartiles
  • interpolate from data to make predictions
