What shape graph do you see for many examples of continuous variation?
 A A straight line downwards B A straight line upwards C A bell-shape D A flat line
Explanation:

Detailed explanation-1: -The frequency distribution of a characteristic that presents a continuous variation is a normal distribution curve with a typical bell shape.

Detailed explanation-2: -This type of graph is called a histogram and is likely to look something like this: If your sample is size is large enough, a graph of continuous variation of an organism will almost always have a shape like the one above. This is known as normal distribution.

Detailed explanation-3: -Examples of continuous variation include things like a person’s height and weight. Examples of discontinuous variation include a person’s blood group or the color of a species of bird.

Detailed explanation-4: -There is no range of data. What chart do you use to plot discontinuous variation? You use a bar chart with gaps between the bars. This is because there is no range of data.

Detailed explanation-5: -Which are examples of discontinuous variation? Discontinuous: Eye colour, handedness & lobed/lobeless ears. Continuous: Hand span, arm length & height.
