make inferences based on the graphical repre- sentation of data (e.g., an inference about a sample from the graphical representation of a population), and justify conclusions orally or in writing using convincing arguments
1.6
make and justify conclusions about a topic of personal interest by collecting, organizing (e.g., using spreadsheets), representing (e.g., using graphs), and making inferences from categorical data
1.7
explain how the media, the advertising indus- try, and others (e.g., marketers, pollsters) use and misuse statistics
1.8
gather, interpret, and describe information about applications of data management in the workplace and in everyday life

1.12
compare, through investigation, the theoretical probability of an event with the experimental probability, and describe how uncertainty explains why they might differ

1.14
interpret information involving the use of probability and statistics in the media, and describe how probability and statistics can help in making informed decisions in a variety of situations

Key ideas

  1. Bar graphs, broken-line graphs, and histograms each show data in a slightly different way.

  2. Theoretical probability is the ratio of favourable outcomes to all possible outcomes, when every outcome is equally likely.

  3. Reading a graph well means checking its title, axis labels, and units before drawing conclusions.

  4. Probability can be shown as a fraction, a percent, or a decimal between 0 and 1.

  5. A population is everyone or everything you're interested in; a sample is a smaller group taken from it.

Watch out for

  • Skipping the axis labels and misreading what the graph actually measures.
  • Miscounting the total number of possible outcomes when calculating a probability.
  • Assuming every graph type works the same way without checking which type it is.

Key ideas

  1. Financial implications include new costs like rent and furnishings, and new financial decision-making.

  2. Non-discretionary expenses (rent, groceries, utilities) must be paid; discretionary expenses (entertainment, vacations) are optional.

  3. Most Canadians are expected to file a personal income tax return every year.

  4. Non-financial implications include more freedom, but also new demands like time management or possible loneliness.

  5. Knowing this distinction helps decide where to cut back if money is tight.

Watch out for

  • Focusing only on the financial side and ignoring non-financial changes like time management.
  • Treating a discretionary expense (like a streaming subscription) as non-discretionary out of habit.
  • Thinking only high earners need to file a tax return.

Key ideas

  1. Tools like a measuring tape, metre stick, and measuring cups each suit different measurement tasks.

  2. The 3-4-5 triplet is a practical trick for constructing a true right angle without special tools.

  3. A ratio compares two quantities of the same kind; a rate compares two quantities of different kinds.

  4. Canada uses metric officially, but imperial units (feet, inches, cups) are still common in daily life.

  5. This trick works because 3² + 4² = 5², connecting directly to the Pythagorean theorem.

Watch out for

  • Misreading a measuring tool's scale, especially between metric and imperial markings.
  • Using the wrong ratio (not 3-4-5) and ending up with an inaccurate angle.
  • Thinking two ratios with different numbers can't be equivalent.
