Background Is being physically strong still important in today’s workplace? In our current high-tech world one might be inclined to think that only skills required for computer work such as reading‚ reasoning‚ abstract thinking‚ etc. are important for performing well in many of today’s jobs. There are still‚ however‚ a number of very important jobs that require‚ in addition to cognitive skills‚ a significant amount of strength to be able to perform at a high level. Take‚ for example‚ the job

Test Anxiety and Student Performance Abstract Test anxiety is a real and measureable problem student’s face regardless of their grade or level of academic achievement. Test anxiety can also adversely affect how students participate in and view the learning process long term. This study was designed to examine the effects of test anxiety on high school students specifically‚ and how the stress associated with the processes or outcomes of standardized testing can negatively impact their performance

purpose‚ data were obtained from 110 firms within and around the Kocaeli Industrial Region. In order to test the hypotheses of this study‚ correlation and regression analyses were performed. Results of correlation analysis revealed that all variables are positively related to both financial performance and to each other. The findings from regression analysis reveal that both marketing and manufacturing performance have statistically significant positive effect on a firm’s financial performance. Human

which is by linear regression analysis. Regression analysis includes any techniques for modeling and analyzing several variables‚ when the focus is on the relationship between a dependent variable and one or more independent variables. More specifically‚ regression analysis helps one understand how the typical value of the dependent variable changes when any one of the independent variables is varied‚ while the other independent variables are held fixed. Most commonly‚ regression analysis estimates
