Conclusion We designed an RNG which is combination of 4 simple generators. we have tested and shown that the final RNG gives uniform distribution and passes 9 different complex tests which suggests that the designed RNG is enough random and can be used for simulation studies or other purposes. Empirical studies also proves that by combining two or more simple generators, by means of a simple operations such as +, -, * or (exclusive-or), provides a composite with better randomness than either of the components[ G. Marsaglia. A current view of random number generators, 1984].
A negative value indicates a distribution which is more peaked than normal, and a positive kurtosis indicates a shape flatter than normal. An extreme positive kurtosis indicates a distribution where more of the values are located in the tails of the distribution rather than around the mean (Grad pad, 2013). A kurtosis value of +/-1 is considered very good for most psychometric uses, but +/-2 is also usually acceptable (Grad pad, 2013). The above graph shows GPA with a kurtosis of -.811; awhile the final kurtosis is -33.2. The extent to which a distribution of values deviates from symmetry around the mean is the skewness.
In the table NPAR stands for Number of parameters, and CMIN (x²) is the minimum discrepancy and represents the discrepancy between the unrestricted sample covariance matrix S and the restricted covariance matrix. Df stands for degrees of freedom and P is the probability value. In SEM a relatively small chi-square value supports the proposed theoretical model being tested. In this model the x² value is 334.687 and is small compared to the value of the independence model (3971.586). Hence the x² value is good.

MI theory is used as formal and informal assessment in the classroom to allow students to be grasp and understand concepts. The use of multiple types of assessments in the classroom yield richer and more qualitative information about a child's achievement. If the ultimate goal is student learning, then there is a place for both standardized testing and authentic assessment using the MI theory in today's classroom.
It’s important to understand that the mean does not represent an individual – there may be no individual whose value matches the mean; but the mean is a summary of the entire population. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. The sum divided by the count. The median is almost always more representative of a typical member of a group. If you take all of the numbers in a list, and arrange them from lowest to highest, or vice versa, if there is an odd number, the number at the middle will be the median.
FPGA is used in general in these systems due to low cost and high computing speed with reprogrammable property. 3.2 Lifting Scheme for 1-D DWT using 9/7 Filter The basic idea behind the lifting scheme is very simple; try to use the correlation in the data to remove redundancy [3, 4]. First split the data into two sets (split phase) i.e., odd samples and even samples as shown in Fig. 3.2[1, 2]. Because of the assumed smoothness of the data, we predict that the odd samples have a value that is closely related to their neighbouring even samples.
n The variance of the distribution of the sample mean is equal to the variance of the sample mean divided by the sample size. These are true whatever the distribution of the parent population. The Central Limit Theorem allows predictions to be made about the distribution of the sample mean without any knowledge of the distribution of the parent population, as long as the sample is large enough. For this reason, the sample size will be set at 50, which I consider large enough for the distribution of its mean to be normal (according to the Central Limit Theorem). It should not be larger because the aim of this investigation is to carry out a “small scale survey” How / What Data to be Collected The sample will be of the weight of 50 smarties.
Experimental results show that their proposed technique is tolerant to off-axis eye images, specular reflections, non-uniform illumination; glasses, contact lens, hair, eyelashes, and eyelids occlusions. Li, P., et. al  also introduce a robust iris segmentation algorithm based on the Random Sample Consensus (RANSAC). According to their experiment, this algorithm can localize the iris boundaries more accurately than the methods based on the Hough transform. Li, P., et.
However, many students freeze under normal testing procedures and may need to be evaluated in another manner. Also, it is important for teachers to understand fair grading procedures so students can best benefit from effective tests. By knowing the main ways of measuring student achievement, and proper formats for grading, students can be evaluated correctly. (Fairtest, 98) There are two main ways of evaluating a student’s work: objective tests and essay questions. Objective testing places emphasis on a precise, efficient focus on a student’s knowledge of defined variables (Kopeikin, 2000).
While the process is nearly as important as the product, as educators, we want students to be solving problems appropriately. Parents, administrators, and school board officials (as well as teachers) want to know that students are learning skills that follow the curriculum. Additionally, students need to know that they are solving problems correctly, and if they are not, the teacher needs to determine why that is the case. Evaluation of This Plan Appendix
