Abstract: The concept of statistical convergence of a sequence was first introduced by H. Fast. Statistical convergence was generalized by R. C. Buck, and studied by other authors, using a regular nonnegative summability matrix in place of ${C_1}$ .

The main result in this paper is a theorem that gives meaning to the statement: $S = \{ {s_n}\}$ converges to statistically if and only if "most" of the subsequences of converge, in the ordinary sense, to . Here is a regular, nonnegative and triangular matrix.

Corresponding results for lacunary statistical convergence, recently defined and studied by J. A. Fridy and C. Orhan, are also presented.
