Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What kind of data suits a line chart?

    Model answer

    Continuous data that changes over time, such as temperature, rainfall or population through a run of years.

  2. 2

    What is a bar chart used for?

    Model answer

    Comparing separate categories, with the height or length of each bar showing its value.

  3. 3

    What does a pie chart show?

    Model answer

    How one total is divided up, with the size of each sector showing that part's share of the whole.

  4. 4

    What is a pictogram?

    Model answer

    A chart using a repeated small picture, each standing for a fixed number of items, with part of a picture used for part of that number.

  5. 5

    What makes a histogram different from a bar chart?

    Model answer

    A histogram shows continuous data grouped into classes so its bars touch, while a bar chart shows separate categories with gaps between the bars.

  6. 6

    Why must the classes of a histogram be of equal width?

    Model answer

    If they are not, wider bars cover more of the data than narrow ones and the heights no longer give a fair comparison.
