experiment is to obtain the grading curve for both fine and coarse aggregate. APPARATUS 1. Balance - balance or scale used in testing fine and coarse aggregates shall have readability and accuracy as follows: For fine aggregate‚ readable to 0.1 g and accurate to 0.1 g or 0.1 % of the test load. For coarse aggregate‚ or mixtures of fine and coarse aggregate‚ readable and accurate to 0.5 g or 0.1 % of the test load. 2. Sieves – the sizes and apertures appropriate to the specification of the material

Part 1 Literature Review Researchers have studied personality test for a long history. At one time‚ personality tests were not perceived as a valid selection method. However‚ personality tests are widely used and get generally positive conclusions today. (1) Reliability and validity In recent years‚ there are many researches focusing on the illumination of the value of personality tests as predictors of performance. In 2007‚ Morgeson‚ Campion‚ Dipboye‚ Hollenbeck‚ Murphy‚ and Schmitt cautioned

3b. Chi squared analysis A chi-square test is also referred to X². It is a statistical test that is used to find a significant difference between the observed data to the expected data in one or more groups. To calculate a chi square you have to carry out the equation‚ X^2= ∑▒(O-E)"²" ÷E. Hₒ = this means that statistically there is no change between the observed and the expected frequencies of the results. Hₐ = this means that there is a significant change between the observed and the expected

1. The first step in evaluating a regression model is to determine whether the sign of the estimated slope term makes sense. The second step is to test whether or not the slope term is significantly different from zero. The appropriate statistical test to determine this is a t-test since the true regression error variance is generally unknown. The third check of regression is to evaluate what percent of the variation in the dependent variable is explained by variation in the independent variable
