Graphical representation: Frequency tables and Graphical representation (including line graphs
- 3 things to know
- Component 2
Overview
Recall questions on Frequency tables and Graphical representation including line graphs.
What you need to know
Answer each one before you reveal it.
In a frequency table with 3 participants scoring 0-4, 8 scoring 5-9, 14 scoring 10-14 and 5 scoring 15-19, what percentage scored 10-14?
What kind of data does a histogram display?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What does a frequency table show?
Model answer
It shows how many scores or cases fall into each category or class interval of a data set.
- 2
Describe how you would turn a list of raw test scores into a frequency table.
Model answer
Divide the range of scores into equal class intervals, tally each score into the interval it falls in, then record the total tally as the frequency for that interval.
- 3
A frequency table records 3 participants scoring 0-4, 8 scoring 5-9, 14 scoring 10-14 and 5 scoring 15-19. How many participants took part?
Model answer
Thirty participants took part, since 3 + 8 + 14 + 5 = 30.
- 4
When is a line graph the appropriate display?
Model answer
When a continuous variable is being tracked across an ordered scale such as time or trial number, so that the trend between points is meaningful.
- 5
What kind of data does a histogram display?
Model answer
Continuous data grouped into equal class intervals along the horizontal axis.
- 6
Why do the bars of a histogram touch?
Model answer
Because the horizontal axis is a continuous scale with no gaps between one class interval and the next.
