Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    How is data in a table analysed?

    Model answer

    A table is analysed by comparing values across rows and down columns. The highest value, the lowest value and any pattern should be picked out.

  2. 2

    A norm table rates a Sit and Reach score of 11–14 cm as average and above 14 cm as good. A performer scores 16 cm. How is the score rated?

    Model answer

    The performer's score is rated good. The score of 16 cm is above the 14 cm boundary for average.

  3. 3

    How is a bar chart showing the number of pupils taking part in different sports interpreted?

    Model answer

    The height of each bar shows the number of pupils in that sport. The tallest bar shows the most popular sport.

  4. 4

    What does a line graph show when its line slopes upwards?

    Model answer

    An upward slope shows the value increasing over time. A steeper slope shows a faster increase.

  5. 5

    A line graph of a sprinter's 30 m times over eight weeks slopes downwards. What does this show?

    Model answer

    The sprinter's times are falling, so the sprinter is getting faster. The training programme appears to be improving speed.

  6. 6

    What does a flat section on a line graph of weekly fitness scores show?

    Model answer

    A flat section shows that the scores stayed the same over that period. The performer may have reached a plateau in improvement.
