This single line graph indicates the statistics of student travelling ticket sales in Australia in 2007. The overall trend of this graph is a fluctuation of ticket sales.

The statistics of student travelling ticket sales increased from 10000 dollars until it reached the first peak, 35000 dollars, in middle of March, then it decreased to 20000 dollars one month later. After the middle of April it jumped to 50000 dollars until the middle of June, which was the second top, and then it dropped to 15000 dollars in one month. After August the sales rose dramatically which got the highest point, 75000 dollars, in the middle of October. In the rest of 2007, sales reduced to 30000 in the middle of November, and then it remained stable.

There were a number of possible reasons for these trends. Firstly, Australian school always had three semesters so that it had three holidays which were Easter Holiday, Winter Vacation and Summer Vacation. It may have been a reason for student travel ticket sales reaching peaks in March, June and October. Secondly, each break had different length such as, Easter with one week, Winter Vacation with one month and Summer Vacation with three months. The length of vacation had relative to the sales so that the sales reached the highest point while summer holiday was the longest holiday. Finally, people have made a good preparation before holidays so that the growths were before the holidays.
