Abstract
While it is common practice for researchers in psychology and other
social sciences to use inferential statistical methods such as t-test, F-test,
and chi-square test, it is only the beginning for linguists and investigators
of language acquisition to get acquainted with the full power of inferential
statistics. As the linguistic science becomes more quantitative, there have
been admirable efforts to introduce statistics into the field, with the
publications of several statistics books specifically designed for linguists
(Anshen, 1978; Butler, 1985; Hatch & Farhady, 1982; Woods, Fletcher, &
Hughes, 1986; see Grotjahn, 1988, for a review). However, none of these
books has discussed a very important statistical method for the analysis of
categorical data, the loglinear analysis — a method that has nevertheless
been applied widely in sociology and other social sciences. In this paper, I
will first examine a problem that many researchers in language acquisition
may have encountered, i.e., the limited power of the analysis of
categorical data by the use of chi-square. I will then discuss how loglinear
analysis overcomes the problem. Although descriptions about loglinear
analysis are available in many statistics books, they are in general not
easily accessible to language acquisition researchers because of their
technicality and mathematical flavor. For this reason, I will deliberately
avoid very technical descriptions here, but will instead present the
rationale behind the method, the basic procedures involved in the analysis,
and a real example that makes use of this method to illustrate the
significance of loglinear analysis for language acquisition data..
