Data: For this problem
set, you'll look at a data file containing information about average
temperature change in the Southern Ocean.
Here's the data file: deltaT.mat
The file contains three variables:
decade
indicates the average year for the temperatures
deltaT
mean differences between data collected from ships during
"decade" and data collected from floats during the 1990s, in degrees C
sigma
1 standard error estimates for deltaT
The data for this problem were taken from Gille,
S. T., 2002. Warming of the Southern Ocean since the 1950s,
Science, 295, 1275-1277. (The link will work from
computers on the UCSD network, but may not work give you full access to
