ANCOVAs were used to test hypotheses controlling for virginity. Partner familiarity did not affect likelihood of engaging in sexual intercourse or condom use. This suggests that friend and acquaintance may not be considered different sex relationship types among college students. In terms of vignette ...
I was hoping to use ANCOVA to compare a battery of neuropsychological tests in carriers vs non-carriers, controlling for age, gender and education level and I have three questions about that which I was hoping you could help me with. Firstly, do I have to demean the covariates, before fe...
An ANCOVA was also used to determine whether child weight status [ie, overweight (BMI ≥85th percentile) compared with normal weight] interacted with serving type on amount of entrée consumed. Pearson’s correlation was used to examine the relation between the amount of food served during the ...
test for which it took place. r correlated poorly with mistake magnitude both for volume and timing errors. Whenever a ‘rogue’ sample is suspected its error needed to be considerable for this becoming identified by single sample estimates applied to the other samples. SI-GFR is resistant to ...
Cortisol was measured at three time points: baseline, after relaxation and after completing all of the tests. To evaluate whether HRV predicted cortisol levels a repeated measures ANCOVA was used. Cortisol was entered as a repeated measures factor (baseline, after relaxation, after cognitive tests)...
Analysis of Co-Variance (ANCOVA) was used to evaluate participants’ perception of safety, and the importance of information on various ARTS behaviours. Age and gender were included as covariates, as previous studies have suggested that there may be age and gender differences regarding the use and...
Because much of the time we need to create new rows, we can use variables such as DTYPE to provide information about how each row was derived. For those used to working with a more horizontal dataset and adding columns, it can be a little intimidating to instead have to add rows. The ...
we could expect more efficiency gain when we use augmented estimators. Second, the augmented estimators are more flexible and one can incorporate different models for outcomesY(0) andY(1) (e.g., some other nonlinear models), whereas the regression based methods such as ANCOVA and ANHECOVA can...
However, students usually overestimate their comprehension, which can be caused by a misalignment between the cues used to judge one’s comprehension and the cognitive requirements of future test questions. Therefore, reading instructions might help students to use more valid cues and hence to make ...
The control group (n = 46) were given static images of the front and back of the garment on the model to view on an iPad (seeFig. 2). The vision group (n = 79) used Shoogleit rotate technology on an iPad. This allowed them to use their fingertips to rotate the model in the ga...
