Interpreting graphs

Trends

This is a common type of question where you have to look at the results displayed in a graph and decide what the overall result is.

An upward trend

A line graph comparing the year, along the x axis, with sales, in millions of pounds. A wiggly diagonally upwards line shows what happened. In 1992, sales were a bit below 2 million pounds, in 1994 they were about 3 million, in 1996 it was about 5 million, and in 1998 it's gone above 7 million.

In the graph above we do not have a nice straight line increase in figures, but overall there is an increase in sales. If asked what the trend was we would say that sales were increasing.

A downward trend

A graph showing the year across the x axis and sales in millions of pounds up the y axis. In 1992 sales were about 6 million, in 1994 they were just under 5 million, in 1996 they were 2 about 2 million, and in 1998 they fell below 1 million.

In this graph we would say that sales were decreasing or dropping.
