Question

Illustrate the following results (representing the average weight of a boy at different heights) by a broken line graph.

Height (in cm)	70	75	80	85	90	95	100	105
Weight in kg	37	40	42	46	52	55	56	60

Answer 1

Here is the broken line graph showing the relationship between a boy’s height (in cm) and his average weight (in kg).

As height increases from 70 cm to 105 cm, weight also increases steadily from 37 kg to 60 kg.

This graph clearly shows a positive correlation between height and weight.
