C) 1530
D) 1550
We know that our list includes 8 values, so our median would be the average of
the fourth and fifth values. Choices A, B, and C would all become the fifth value
in the list and none will yield a median of 1520. Only choice D will become the
sixth value, so that 1500 and 1540 will yield our desired median, 1520.
The SAT requires fast thinking in difficult situations. So here’s a scenario—you
have approximately three seconds to come up with the appropriate response:
A psychotic iguana with a bottle of dishwashing detergent is chasing
you and gaining every second. The soft grass you’re running on
barefoot suddenly ends and you’re faced with the option of treading on
a minefield strewn with broken glass or walking across a river of
flowing lava. Which do you choose?Answer: Neither, of course! I’d much rather face an iguana (even a psychotic
one with detergent) than deal with a minefield or hot lava. So remember, if you
really don’t like any of your choices, then “it cannot be determined from the
information given” may be an option.
