چکیده (انگلیسی):

In the field of research, there are a variety of statistical
methods used. Hypothesis testing is one test that is often used to obtain
the conclusions of the research conducted. One hypothesis testing that is
often used is the testing of hypotheses through ANOVA (Box et al.,
1978). However, in determining the validity of a hypothesis is obtained,
there are assumptions that must be met, namely the assumption of
homogeneity range between treatments (Box et al., 1978; Box and Cox,
1964; Gomez and Gomez, 1984; Guerrero, 1993; Mattjik and Made,
2006). Examination of a wide homogeneity assumption has been made in
research involving plants, which use a randomized block design. Wide
homogeneity assumption was tested using Bartlett test, but from the tests
that have been done show no results were less consistent (Box et al.,
1978; Box and Cox, 1964; Gomez and Gomez, 1984; Guerrero, 1993;
Mattjik and Made, 2006). Transformation Box-Cox used to transform
data that is not homogeneous (Box et al., 1978; Box and Cox, 1964).
Calculation of the variance range and test computer-based transformation
has been compiled using C # programming language.
