Predicting Parent Smoker Identity Four logistic regression analyses determined whether the scores from the 2 IRAP trial types on which the two groups differed significantly (smokers-positive and nonsmokers-positive) would increase the variance accounted for
by either of the self-report measures.
The short duration of the study is also a limitation: I am reporting three years of data, and every semester the data analysis has been done, the percentage of variance accounted for
in each regression model has increased, so with more participants the proportion ofvariance accounted for by the predictor variables might grow
Consequently, with multiple linear regression there was no gain in the percentage of variance accounted for
by combining [Na.
These complementary interpretation criteria include: the factor loadings of variables; the percentage of variance accounted for
by the components; and the interpretability of the resulting factors.
Hypothesis 1: Emotional intelligence will add significant incremental variance beyond the variance accounted for
by personality traits in relation to the Routine Seeking factor of the RCS (Di Fabio, 2011; Di Fabio & Palazzeschi, 2009b; Vakola et al.
To determine which model best represents the sample data the following four techniques will be discussed: 1) comparison of model fit statistics, 2) ratio of variance accounted for
by the general factor over the variance accounted for
by the specific factors, 3) the degree to which total scores reflect a common variable, and 4) the viability of reporting subscale scores as indicated by subscale reliability.
It is interesting that, although smaller than the variance accounted for
by goal selection and planning, changes in students' self-efficacy regarding their ability to obtain occupational information and their ability to engage in self-appraisal accounted for an equal proportion of the variance.
2] = the amount of variance accounted for
in the criterion variable by the predictor variable R squared Ranges from 0 to 1.
Percentages of total variance accounted for
by each component are reported in parentheses.
self-efficacy, the overall percentages of variance accounted for
These analyses permit a comparison of the variance explained by individual skills/abilities with that explained by the underlying cognitive and technical/motor factors, and a determination of the incremental variance accounted for
by individual skills/abilities after controlling for the underlying cognitive and technical/motor factors.
As can be seen, the percentage of variance accounted for
by all three blocks of variables ranges from 13.
