“…Descriptive statistics are often referred to as frequency distributions that provide accurate measurements from the smallest to the largest data (Hartanto & Yuliani, 2019;Khosharay et al, 2018;Al Mutairi, 2018). The descriptive statistics used in its presentation use estimated and experimental values, from two parameters, namely the mean, arithmetic, and standard deviation (Khalil & Najm, 2018;Haj-Kacem et al, 2017;Lapinova & Saichev, 2017). By using this type of associative research to determine the relationship or type of variable used.…”

This study aims to determine the differences and the relationship between interest and science process skills with 80 female students and 56 male students. This research uses quantitative methods so that this research is more systematic and objective. The sampling technique used in this study used simple random sampling. Analysis of the data used using hypotheses in the form of normality, linearity and homogeneity tests and assumption tests in the form of T test and correlation test. From the results of the T test and correlation test, it was found that there were differences and relationships between the sexes in the interests and skills of class VIIA and VIIB. In this case it is evidenced by a significant value 0.05. Thus, the higher the interest of students, the higher the skills of students according to their gender. It can be said that success can be seen from the level of understanding, mastery of the material, and student achievement. The higher the understanding and mastery as well as learning achievement, the higher the level of learning success.

Prediction and estimation of physicochemical properties of binary mixtures are of high importance for understanding the structure and molecular interactions. Excess and deviation properties exhibiting non-linear behaviour in methyl benzoate + n-Octane binary liquid mixtures at (303.15, 308.15, and 313.15) K for density and viscosity experimental values were presented in our earlier work. Here these experimental and calculated values were utilized to explore the applicability of the predictive Haj-Kacem equation and the recently proposed Messaâdi equation as well as their corresponding relative and derivative functions. Their correlation ability at different temperatures, with different parameters are also discussed in the case of limited experimental data. These relative functions are important to reduce the effect of temperature and, consequently, to unveil the effects of different natures of interactions. Despite the quasi-equality between the enthalpy for viscous flow activation ΔH*, and the viscosity Arrhenius energy of activation Ea, it limits excess partial molar energy of activation Ea1 and Ea2 for methyl benzoate and n-Octane, respectively, are investigated, along with their individual contributions independently. Molar activation energies at infinite dilution were deduced from different methods, activation parameters and partial molar Gibbs energy of activation for viscous flow against compositions were investigated. The results of these observations have been interpreted in terms of the structural effects of the solvents. In this context, a correlating equation is proposed in the present work and to estimate the normal boiling temperature of pure constituents and the nature of the isobaric vapour-liquid diagram in the binary liquid mixture. The obtained equations present a satisfactory result and are expected to be useful for future studies.
