The changes in seasonally adjusted prices for used cars and trucks between March 2010 and September 2010 were in most cases less in magnitude than the changes in seasonally adjusted prices of new vehicles for the same period.
question 1 asked about "The changes" in seasonally adjusted prices not "relative changes" ( percent increase or decrease) in that case how can we use the table which talks about the relative changes ? Meaning the starting price of a particular category could be very different and thus "the changes" could be very high or low in magnitude
for ex:
category 1 has a starting price of billion dollars -> then 0.1 increase could be a large amount
while category 2 has a starting price 100 dollars -> then 0.5 increase would still be a small amount relatively.
But from Manhattan explanation posted by one of the user above, it looks they are just comparing the relative change value directly.
Please explain!
