We attempt to establish a correlation between the solar activity level and some characteristics of the latitude
distribution of sunspots by means of center-of-latitude (COL) of observed sunspots. We calculate
the COL by taking the area weighted mean latitude of sunspots for each calendar month during a cycle,
and adopt the cycle-integrated sunspot area as a measure of the strength of a cycle. We first determine
the latitudinal distribution of COL of sunspots. We then compute three different statistical correlations
between the cycle-integrated sunspot areas and the fitting parameters of all sunspot cycles from 1878
to 2009. Our main findings are as follows: (1) The distribution of COL is bimodal well represented by a
double Gaussian function. (2) Ignoring cycle 19, the characteristic width of the distribution of COL shows
a significant correlation with the cycle amplitude. (3) A correlation between the location of the maxima of
the COL distribution (either centroid1 or centroid2) and the sum of sunspot area can be found, when the
data point corresponding to the solar cycle 19 is omitted.
