A statement was supported, when the chi-square
value was found greater than the table value of 3.
During the bivariable analysis, qualitative variables were tested for significance using chi-square
test and quantitative variables using t-test.
Responses based on the characteristics of the students, and the schools from which they came, were examined for differences using chi-square
The degree of association of a form with a class is assessed by applying the chi-square
formula on the observed data.
Andersen (1973) showed that -2 times logarithm of the difference between the maximum likelihood (ML) of the whole sample and sum of likelihoods of the subsamples is asymptotically chi-square
distributed with (g-1) (k-1) degrees of freedom, where g and k are the number of score groups and the number of items, respectively.
test (x2) was used to analyze differences in allelic frequencies and to verify Hardy-Weinberg equilibrium.
Differences in baseline characteristics of participants as a function of gender were also assessed through Chi-square
test, and independent sample t-test or Mann-Whitney test if parametric assumptions were not met.
tests (Preacher, 2001) were utilized for testing for pairwise differences of the medians of the different developmental stages in the four different oxygen levels on a specific day.
In Table 4, the chi-square
tests for GHP (Chi-square
The first part indicates it is a chi-square
test, and the number in parentheses represents the degrees of freedom.
tests of independence were performed between each of the 7 professional characteristics and the 18 CPE needs.
We compared the groups on demographic characteristics using t tests for continuous variables and chi-square
tests for categorical variables (Hays, 1994).
