Question

1. students are looking at the amount of organic matter in soil taken at different depths. why should they use a line graph to represent their data? the data are interchangeable for both x and y, so the students do not need to know which axis is horizontal and which axis is vertical. a line graph would show the changes between the variables of the amounts of organic matter and the depth. the data may be converted to a percentage, which is best to use in a line graph. a line graph would show the depth of the soil as the whole and the different amounts of organic matter as the parts.

Explanation:

A line - graph is ideal for showing changes over a continuous variable. Here, the depth of soil is a continuous variable and the amount of organic matter changes with soil depth. So, a line graph would show the changes between the variables of the amounts of organic matter and the depth.

Answer:

A line graph would show the changes between the variables of the amounts of organic matter and the depth.
