But these experiments [2] will not give us any information about the dependence or independence of the two factors, namely study habit and home environment. In such cases, we resort to Factorial ANOVA which not only helps us to study the effect of two or more factors but also gives information about their dependence or independence in the same experiment. There are many types of factorial desig...

Measurement bias refers to systematic differences across subpopulations in the relation between observed test scores and the latent variant underlying the test scores. Comparisons of subpopulations with the same score on the latent variable can be expected to have the same observed test score. Measurement invariance is therefore one of the key issues in psychological testing. It has been establ...

and Applied Analysis 3 It follows from 1.11 or 1.12 that t n, k t n − 2, k − 2 − 1 4 n − 2 t n − 2, k , 1.13 and that t n, 0 δn,0 n ∈ N0 : N ∪ {0} , t n, n 1 n ∈ N , t n, k 0 n k odd , t n, k 0 k > n or k < 0 , 1.14 where δm,n denotes the Kronecker symbol. By 1.13 , we have t 2n 1, 1 −1 n 2n ! 42n ( 2n n ) , t 2n 2, 2 −1 n n! 2 n ∈ N0 , 1.15 t 2n 2, 4 −1 n 1 n! 2 ( 1 1 22 1 32 · · · 1 n2 ) n ∈ ...

a 3×3 factorial arrangements experiment was conducted to evaluate the effect of fennel extract and vitamin d3 on performance, hatchability, chick quality characteristics and immunity. this experiment was done with using 360 ross 308 broiler breeders after molting (84 - 92 weeks) in a completely randomized design with three levels (0, 50, and 100 mg/kg of diet) of fennel extract and three levels...

Two face identification experiments were carried out to study whether and how children (5-year-olds) and adults integrate single facial features to identify faces. Using the paradigm of the Fuzzy Logical Model of Perception each experiment used the same expanded factorial design, with three levels of eyes variations crossed with three levels of mouth variations as well as their corresponding ha...

Two experiments were conducted to evaluate the effects of a commercial endo-β-D-mannanase (Hemicell) on overall performance, MEn, net energy for gain, and some serum parameters of broilers fed diets varying in β-mannan level (experiment 1) and to evaluate effects of enzyme level on the same variables in broilers fed diet high in β-mannan (experiment 2). As a semipurified β-mannan source, guar g...

incorporation of functional foods and nutraceuticals such as carotenoids which suffer from poor water solubility and low bioavailability into nano-sized delivery systems can improve their solubility, stability and oral bioavailability. the aim of this study was to prepare β-carotene nanodispersion and investigate the effects of preparation parameters by means of response surface methodology usi...

It is traditional to call a quasi-symmetric design with certain parameters an SDP design if the symmetric difference of two different blocks is either a block or a block complement. In this note, we delete the requirements on the parameters and demand just that the symmetric difference of two blocks be a block, a block complement, or either the empty set or the whole point set. We obtain the pa...
