Continuous and Discontinuous Variation Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What is continuous variation?

Continuous variation refers to characteristics that can have many different values within a range, such as height or weight, and is usually quantitative.

Give examples of continuous variation.

Examples of continuous variation include human height, weight, heart rate, and rate of photosynthesis.

What does a graph of continuous variation typically look like?

A graph of continuous variation typically shows a smooth bell-shaped curve of normal distribution.

What is discontinuous variation?

Discontinuous variation refers to characteristics with a limited number of possible values or categories, like blood type or eye colour, and is usually controlled by a few genes.

Give examples of discontinuous variation.

Examples of discontinuous variation include blood type, eye colour and gender.

How are characteristics of discontinuous variation usually plotted on a graph?

Characteristics of discontinuous variation are plotted as discrete or categorical data, showing well-defined categories that are usually qualitative and unaffected by the environment.
