Vocabulary

What do the words in bold below mean? Take some notes on a piece of paper to aid your memory:

The bar charts display information for the price of airline tickets from Sydney to Melbourne and the reverse flight over a two week period in 2013. Looking from an overall perspective, it is readily apparent that flights in both directions displayed broadly similar patterns with higher prices Friday through Monday. Compared to week 1, week 2 prices were either greatly deflated or identical for nearly all flights.

In week 1, flights from Sydney to Melbourne started at 80$ on Monday, were all under $40 over the next 3 days before a spike to $75, $70, and $50 on Friday, Saturday and Sunday, respectively. During the second week, the prices were unchanged with the notable exception of a decline on Monday to $50 fares.

In terms of flights from Melbourne to Sydney, the trend was comparable with flights on Monday of week 1 elevated to $60, sub-$40 flights on Tuesday, Wednesday, and Thursday and the most expensive flight on Friday at $80. Flights on Saturday and Sunday were also relatively costly at $60 and $50 each day. In week 2, Monday prices displayed a dramatic decline to $40 and there was more variance later in the week. Friday fell to $50 and Saturday to $50. All other tickets remained the same in week 2.
