Final answer:
Ratios can show how figures relate to each other over time but do not explain why changes occur. Additional analysis is needed to understand the reasons behind changes illustrated by ratios. A line graph is an effective way to visualize these relationships and trends over time.
Step-by-step explanation:
The statement 'Ratios exhibit the relationship between figures from year to year and the reason for the changes year to year' is false. Ratios can show the relationship between two figures for a given time frame, but they do not by themselves explain the reason for the change. To understand why changes occur over time, additional analysis is required beyond the computation of ratios. Ratios can be quite revealing in showing trends or shifts when comparing year-over-year data. For instance, if a company's revenue increased by 5% annually, this change could be done effectively using a line graph, which shows the pattern of increasing revenue over time.
Furthermore, understanding proportions, unit rates, and unit scales is crucial when examining relationships between different quantities and dimensions. Graphs, particularly time series graphs, are excellent for showing patterns in data, such as changes in the unemployment rate over a period. When changes happen at a constant raw amount each period, the growth rate will decrease as the baseline figure increases unless the change itself also increases proportionally.
