The line graph illustrates changes in the prices of three types of fuel – oil, gas, and wood – in Australia over a five-year period, from 1991 to 1995. According to statistical analysis, the data shows several important characteristics in the energy sector. This report aims to highlight the main characteristics and contrast the most significant high and low figures.
The most noticeable peak was observed in 1995, when oil reached its maximum price of 9 dollars per unit. This characteristic indicates a sharp increase compared with previous years. Gas remained relatively stable, reaching 6 dollars per unit in 1992, representing the second-highest point. These figures show that oil experienced more dramatic fluctuations than gas.
In contrast, the minimum price for wood was recorded in 1994 at 2 dollars per unit. Oil also dropped to a low of 3 dollars per unit in the same year. Gas prices remained relatively stable during this period, showing only minor variations between 4 and 6 dollars per unit. These characteristics suggest that wood and oil were more volatile than gas.
In conclusion, fuel prices in Australia showed significant variation between 1991 and 1995, with oil and wood displaying more fluctuations than gas. These characteristics highlight the instability of certain energy sources, which may affect consumers and economic planning.
