One of our subscribers asked me for a sample answer. Enjoy!
The line graph compares the amount of money spent on monthly contracts. It covers four mobile operators over the first three quarters of the year 2002 in a country in Europe.
Overall, contract costs increased for Domo, Lex and Alpha, with the last operator showing a significant rise at the end of the third quarter, while Sim TX, despite initial increases, closed the third quarter with the same amount it had in the beginning.
During the first quarter, almost all companies experienced growth. Sim TX’s figure dipped slightly in February but was able to recover quickly by March at 9 euros per contract. Both Lex and Alpha rose by a negligible 1 euro, with the former going from 12 euros to 13 euros and the latter from 5 euros to 6 euros. Meanwhile, the most expensive operator, Domo, recorded a stable rise and closed the first quarter with 17 euros.
The following six months were somewhat volatile, and all operators swapped their original positions as September drew near. The greatest increase was seen in Alpha: after a brief period of decline to 5 euros, the contract costs in this company skyrocketed to 25 euros in the third quarter, showing the highest figures among all. The prices of Domo and Lex also went up, albeit rather modestly and with short periods of stability and decreases. Domo finished at 23 euros, just behind Alpha, and Lex was third at 18 euros. The only company that showed an overall fall was Sim TX. Although it recorded rising numbers at 14 euros in June, the figures then plunged back to 8 euros by September, the lowest price of the four.
