Question
What type of graph do we use for discontinuous variation?
- A bell-shape
- Bar chart
- Line graph
- Scatter Graph
Hint:
No line of best fit is required.
The correct answer is: Bar chart
Variation is the difference that is present in the genetic material of the individuals among the same species. The hair color, texture, eye color, height, weight of any two individual is not the same. This is called variation.
Variations can be continuous or discontinuous.
If the trait under study for variation has a limited range of variation, it is called discontinuous. Eye color is a classical example of discontinuous variation. The variations of eye color can be expressed in the form of bar chart knowing the percentage of population under each category of variation.
- Variation is the difference in genetic make up of individuals among same species
- Variation can be continuous or discontinuous
- Continuous variations do not have limited range. Height, weight are classical examples
- Discontinuous variations have limited range. Eye color, blood groups are classical examples
- Continuous and discontinuous variations are expressed in bell- shaped graph and bar graph, respectively
