unconventional graphs
summary
the content focuses on strategies for tackling unconventional graphs and data interpretation questions on the gre, emphasizing the importance of maintaining composure and applying logical analysis.
- unconventional graphs on the gre can range from slightly unfamiliar to completely novel, requiring test-takers to adapt quickly.
- the gre will provide all necessary rules for interpreting these graphs, making careful reading and application of known graph-reading skills crucial.
- examples include interpreting graphs that show relationships between different variables such as volume, pressure, and temperature, or analyzing sales data and currency exchanges.
- estimation and a general understanding of mathematical concepts are often sufficient to answer questions correctly, even without precise calculations.
- maintaining a level head and not being intimidated by unfamiliar graph formats can give test-takers a significant advantage.

frequently asked questions
faq: in the atm and pressure problem, i don't understand how the percent increase was 50%. can you explain a bit more?
a: so, we're increasing from 50 to 75.
by our percentage change formula, we take the "change" and divide it by the original value.
so, our "change" is:
75-50 = 25
we then divide this by our original number -- 50:
25/50 = 1/2 = 0.5
finally, we multiply by 100 to turn it into a percent:
0.5 x 100 = 50% increase
