The Power of Tests in Configural Frequency Analysis

Article excerpt

Summary, Zusammenfassung

Specification of a zero hypothesis is central to the interpretation of types and antitypes in Configural Frequency Analysis (CFA). When the observed frequency of a variable category exceeds (or is less than) its corresponding expected frequency, the variable category is considered a type (or antitype). This article attempts to help the researcher to determine whether types or antitypes can be expected to emerge based on power and sample size considerations. Results are presented for the special cases of 2x2 and 2x2x2 tables respectively for first order CFA.

Key words: Configural Frequency Analysis, Power Analysis, Sample size Zur Power von Tests in der Konfigurationsfrequenzanalyse

Die Spezifikation von Nullhypothesen ist ein zentraler Aspekt bei der Interpretation von Typen and Antitypen in der Konfigurationsfrequenzanalyse (KFA). Ist die beobachtete Haufigkeit einer Konfiguration groBer (oder kleiner) als die korrespondierende erwartete Haufigkeit, dann konstituiert these Konfiguration einen Typ (oder Antityp). In diesem Artikel wird auf der Basis von Uberlegungen zur statistischen Power and zur Stichprobengr&Be gezeigt, wie man feststellen kann, ob Typen and Antitypen erwartet werden konnen. Ergebnisse werden fir die Spezialfille der 2x2 and 2x2x2 Tafeln fur die KFA erster Ordnung prasentiert.
