Life Situations Represented through Graphs Essay

Life Situations Represented through Graphs - Essay Example The total amount paid in electricity bills for the last 10 months was $384, meaning that The average amount of electricity bill per month was $384/10 = $38.4 During 5 of the last 10 months, the electricity bill was above average of $38.4 and for the remaining 5, it was below the average amount. In terms of trend, the monthly electricity cost for the house increased from October 2010 onwards and reached a maximum of $49 in December 2010 before starting to decrease again. It has been decreasing since then. The graph is non-linear as no three successive points lie on the same line; although, the overall graph looks like a half sine curve with a clear peak during December 2010 and January 2011. The months of December 2010 to February 2010 had very high electricity bills compared to other months. In other words, the winter months had much higher electricity bills compared to spring and fall. This means that the consumption of electricity is rather seasonal. This seems natural as there is no heating required in the house during spring and fall, while the heating appliances are kept on during the winter months, which increases the consumption of electricity. It is likely that this trend would continue over the years although the peaks and the troughs in the graph can be brought lower by using energy efficient devices. References Glencoe. (n.d.).
