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 were
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.
