Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is the difference between a pattern and a trend in data?

    Model answer

    A pattern is a regular feature in data, such as one group scoring higher than another. A trend is a general direction of change over time.

  2. 2

    What is a line graph best used to show?

    Model answer

    A line graph shows how something changes over time. The number of marriages each year could be shown as a line graph.

  3. 3

    What is a bar chart best used to show?

    Model answer

    A bar chart compares amounts across separate categories. A bar chart could compare the number of pupils excluded in different regions.

  4. 4

    What does a pie chart show?

    Model answer

    A pie chart shows how a whole is divided into parts. Each slice represents a share of the total, such as the share of households of each type.

  5. 5

    A line graph shows the number of divorces falling in most years over a decade. How should a sociologist describe the trend?

    Model answer

    The trend in divorces is downwards over the decade. The sociologist should also note any single year that rose against the trend.

  6. 6

    A table shows that 120 of 400 households in a survey are headed by a lone parent. What percentage is this?

    Model answer

    Lone-parent households make up 30% of the survey. The working is 120 ÷ 400 × 100 = 30%.
