Overview+statements

= = toc =Double Line Graphs= A double line graph is used to **compare** two sets of data. Therefore, we need to think about **how the two lines are similar and different**, not just look at the trend of each line separately. //Remember that you are drawing a description with words - the reader should be able to 'picture' (see) the graph is his/her mind after reading your text.//

=Overview statements= Remember that there may be different ways to make a general statement. Read the statements and decide how effective you think they are. There are some **errors** in ** red **- try to correct them.

= **Graph 1** =
 * **Overall**, both X and Y ** shows ** an upward trend. **However**, X ** is increased ** more rapidly than Y.
 * **It is clear that** X increased rapidly, **whereas** Y increased steadily but less dramatically / at a less dramatic rate.
 * **Overall**, **while** X and Y both increased considerably during the period, X's rate of increase was faster than Y's.
 * **Overall**, **while** X and Y both ** increase **significantly over the period shown, the increase in X was far greater.

= **Graph 2** =
 * **Overall**, x increased ** steady ** throughout the period, **while** y rose dramatically **before** ** declined ** rapidly in 1994.
 * I**t can be** ** see ** **from the graph that** Y increased sharply to a peak in 1994 **which was followed by** a rapid decline, **while** Y steadily increased over the same period.
 * I**t is clearly from the graph that** X increased significantly throughout the period, **while** X peaked in 1994 **before fell **again dramatically.

= **Graph 3** = > //(the last part in italics would be expected for a good grade in IELTS)//
 * **Overall**, Y declined gradually over the period, while X increased significantly, //overtaking Y in 1992//
 * **It can be seen that** Y was ** more high ** **than** X at the beginning of the period. **However,** X rapidly overtook Y and rose at a faster rate **than** Y declined.

= **Graph 4** =


 * **It can be seen that** both X and Y rose significantly **until** 1993, **when** Y began to fall, **while** the number of X continued to increase steadily.
 * **Overall,** both X and Y increased at a similar rate **until** 1993, **After that** X continue to increase rapidly, **while** Y decreased dramatically.
 * **Overall, it can be seen that** both X and Y rose fairly rapidly until 1993, **but** after this period X continued to rise **whereas** there was a significant drop in Y.
 * **Overall,** X and Y showed a similar strong upward trend until 1993, **when** X continued to increase **while** Y began falling rapidly.
 * ** It can be seen that ** X and Y showed a similar strong upward trend until 1993 **when** the trends diverged. X continued to rise at the same rate, **while** Y fell significantly after this point.

= **Graph 5** =


 * **Overall,** Y declined significantly **while** X fluctuated moderately throughout the period.
 * **It is clear that** Y fell considerably **whereas** X fluctuated moderately during the same period.

= **Graph 6** =


 * **Overall,** x fell ** slightly **while y rose dramatically until 1993. **However**, after this period, both x and y declined steadily.
 * **Overall**, X declined steadily until 1993, **while** Y increased significantly during the same period. **However**, they both decreased gradually from this point onward.
 * **It can be seen from the graph that while** there were more Xs than Ys throughout the period**,** both were decreasing steadily at a similar rate by 1993.
