Key Vocabulary Chart Vertical Discrete data

Vertical line charts are used when data is discrete. The outcomes are marked at equal intervals along the x-axis. The frequency is marked up the y-axis.

Example Parents in a Y 10 class were asked how many times their son or daughter had to be told to do their homework before they actually did it. Number of reminders Frequency 0 2 1 5 2 8 3 14 4 7 5 4 6 0 Note that the gaps between values on the x-axis is always the same size, and the vertical lines are the same thickness.

Now try these…… 1. Draw a vertical line chart for the following data. Colour of cars White Red Black Blue Other Frequency 5 8 3 4 1

Now try these…. 2. Draw a vertical line chart for the following goals scored by a football team last season Goals scored 0 1 2 3 4 5 Frequency 15 20 5 2 2 2

Reason and explain How do the gaps differ on the x-axis? The gaps are always the same size What type of data do you use a vertical line graph for? Discrete data How thick must the vertical lines be? Just the thickness of a pen Use a pen as pencils are sometimes difficult to see
