Continuous variation: data handling and analysis
I can plot data on continuous variation on a histogram and suggest possible causes for the variation.
Lesson details
Key learning points
- Using a histogram or line graph to display continuous data.
- Plotting data for continuous variation on a histogram.
- Interpreting and describing a histogram displaying data for continuous variation.
- Continuous variation is usually influenced by many factors, including genetics, the environment and lifestyle.
Common misconception
Using a bar chart to plot continuous data. Features with continuous variation are only due to genetic factors.
The lesson explores why a histogram or line graph is the correct choice for plotting discontinuous data, and the idea that continuous variation is usually influenced by many factors, including genetics, the environment and lifestyle.
Keywords
Continuous variation - Variation which can take any one of many values over a continuous range.
Line graph - A graph displaying continuous data plotted as points joined with a line.
Histogram - A graph displaying continuous data grouped into ranges and plotted as columns that touch.
Environment - Factors in an organism’s surroundings that influence its features.
Genetic - Related to the genetic material (DNA) and genes that an individual has.
