OK, so the median is based on data we don't see, and we just pick the middle without regard to any order but the given one. But I still don't understand.
4 makes sense for cat, being (2+6)/2, but how does one get 3 for dog? That's the last element, not the middle. I wondered if maybe they were line numbers instead, but that doesn't make sense either.
The median is the middle element of the list after that list has been sorted.

grdinfo
GRDINFO(l) GRDINFO(l)
NAME
grdinfo - Get information about the contents of a 2-D grd file
SYNOPSIS
grdinfo grdfiles [ -C ] [ -D ] [ -F ] [ -L1 ] [ -L2 ] [ -M ] [ -V ]
DESCRIPTION
grdinfo reads a 2-D binary grd file and reports various statistics for the (x,y,z) data in the grdfile. The output information contains the
minimum/maximum values for x, y, and z, where the min/max of z occur, the x- and y-increments, and the number of x and y nodes, and
[optionally] the mean, standard deviation, and/or the median, L1 scale of z, and number of nodes set to NaN.
grdfile
The name of one or several 2-D grd files.
OPTIONS
No space between the option flag and the associated arguments.
-C Formats the report using tab-separated fields on a single line. The output is w e s n z0 z1 dx dy nx ny [ x0 y0 x1 y1 ] [ med scale
] [ mean std rms] [n_nan]. The data in brackets are output only if the corresponding options -M, -L1, -L2, and -M are used, respec-
tively.
-D Report grid domain and x/y-increments using dd:mm:ss[.fff] notation [Default is decimal]. Does not apply to the -C option.
-F Report grid domain and x/y-increments world mapping format [Default is generic]. Does not apply to the -C option.
-L1 Report median and L1 scale of z (L1 scale = 1.4826 * Median Absolute Deviation (MAD)).
-L2 Report mean and standard deviation of z.
-M Find and report the location of min/max z-values, and count and report the number of nodes set to NaN, if any.
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
To obtain all the information about the data set in file hawaii_topo.grd, try
grdinfo -L1 -L2 -M hawaii_topo.grd
