<p>This thesis examines the estimates of pupils' performances in School Certificate made by teachers at Hutt Valley High School over a six year period. It aims to assess the degree of accuracy of teacher predictions, in particular at the pass/fail boundary, and to identify and evaluate the relative importance of some correlates of accurate prediction. The data for this study is taken from school records showing for each class the name of the teacher and the estimated and achieved marks of each pupil in School Certificate for the period 1973 to 1978. The statistical analyses include the calculation of the Pearson Product-Moment Correlation Coefficient between the estimated and achieved marks of pupils in English, Mathematics, Science and French. Expectancy tables are provided to give greater detail of the accuracy of teacher's estimates at different points across the mark range. A multiple regression analysis is carried out in order to identify and evaluate the relative importance of some correlates of accurate prediction. The statistical section concludes with a summary analysis of the data from the subjects for the year following the major analysis. The results of the study show that the correlations between the estimated and achieved marks are greater in Mathematics and French than in English and Science, however, the estimated and achieved class means across subjects show greatest agreement in English and least agreement in Mathematics. Whilst variations across subjects and across years occur, in general teachers show a tendency to underestimate pupils at the upper end of the ability range and overestimate the marks of pupils at other points of the scale. A movement of approximately 16.5% across the pass/fail boundary was observed when comparing the estimated and achieved marks of pupils. The study also concludes that the only factor to reveal a substantial and systematic link with the quality of teachers' predictions was the ability level of the class under analysis - teachers were generally more able to predict the results of their pupils for higher ability than lower ability classes (English excepted).</p>

Distribution Of Physicians

Regression analysis was used to analyze the geographic distribution of physicians in the Northeastern U.S. The ratio of general practitioners (GP's) to population, and specialists to population was calculated for each of the 299 counties in the region. The independent variables were categorized into three types of factors: economic, professional, and quality-of-life.Results indicated that both types of physicians responded similarly to economic and quality-of-life variables, but responded differently to professional considerations. This suggests that the urban concentration of specialists vis-a-vis GP's is due primarily to the relative importance of professional considerations to specialists. Policy implications and directions for further research are presented.

Continuously Cast

Free-cutting steel gains specific working properties thanks to the high content of sulfur and phosphorus. These elements, especially sulfur, have a rather high tendency to segregation. Therefore, segregation defects in free-cutting steel continuously cast billets can be significantly developed. The aim of the work was to study the influence of the chemical composition of freecutting steel and casting technological parameters on the quality of the macrostructure of continuously cast billets. A metallographic assessment of the internal structure of cast metal made of free-cutting steel and data processing by application of correlation and regression analysis were the research methods. The array of production data of 43 heats of free-cutting steel of grade A12 was studied. Steel casting on a five-strand radial type continuous casting machine was carried out by various methods of metal pouring from tundish into the molds. Metal of 19 heats was poured with an open stream, and 24 heats – by a closed stream through submerged nozzles with a vertical hole. High-quality billets had a cross-sectional size of 150×150 mm. The macrostructure of high-quality square billets made of free-cutting steel of A12 grade is characterized by the presence of central porosity, axial segregation and peripheral point contamination, the degree of development of which was in the range from 1.5 to 2.0 points, segregation cracks and strips – about 1.0 points. In the course of casting with an open stream, almost all of these defects are more developed comparing with the casting by a closed stream. As a result of correlation and regression analysis, linear dependences of the development degree of segregation cracks and strips both axial and angular on the sulfur content in steel and on the ratio of manganese content to sulfur content were established. The degree of these defects development increases with growing of sulfur content in steel of A12 grade. These defects had especially strong development when sulfur content in steel was of more than 0.10%. To improve the quality of cast metal, it is necessary to have the ratio of the manganese content to the sulfur content in the metal more than eight.

Islamic Bank

Perkembangan dunia perbankan syariah tidak lepas dari peran para nasabah yang memberikan kepercayaan terhadap pihak perbankan untuk penyimpanan asset keuangannya. Faktanya banyak kelompok nasabah yang memutuskan untuk menjadi nasabah di perbankan syariah karena faktor religiusitasnya. Faktor lain yang dapat ikut mempengaruhi keputusan nasabah adalah kualitas produk. Di mana kualitas produk merupakan karakteristik yang melekat dari suatu produk. Kemungkinan yang terjadi bahwa kebanyakan nasabah pada perbankan syariah juga masih merupakan nasabah perbankan konvensional.Tujuan yang ingin dicapai dalam penelitian ini adalah untuk mengetahui pengaruh kualitas produk dan tingkat religiusitas nasabah terhadap keputusan nasabah untuk menyimpan dananya atau tidak di BSM Cabang Purwokerto. Alat analisis yang digunakan adalah analisis regresi linier berganda, dengan jumlah sampel 100 nasabah. Diperoleh hasil Y = 5,046 + 0,101X1 + 0,218X2. Berdasarkan uji F yang sudah dilakukan maka dapat diketahui bahwa variabel kualitas produk dan religiusitas secara bersama – sama berpengaruh terhadap keputusan nasabah untuk menyimpan dananya di BSM Cabang Purwokerto. Berdasarkan uji t yang sudah dilakukan dapat diketahui bahwa secara partial baik variabel kualitas produk maupun variabel religiusitas berpengaruh terhadap keputusan nasabah untuk menyimpan dananya di BSM Cabang Purwokerto. The progress of the Islamic bank cannot be separated from the role of its customers who give trust to the bank to deposit their financial assets. It is a fact many groups of customers decide to be the customers of the Islamic bank because of their religiosity. The other influences factor of a customer’s decision is the quality of the product. The aim of this research was to determine the effect of product quality and level of customers’ religiosity towards customers’ decision whether to keep their funds in Syariah Mandiri Bank, Branch of Purwokerto, or not. The analytical tool used was multiple linear regression analysis, with a sample of 100 customers. The results indicate Y = 5,046 + 0,101X1 + 0,218X2. Based on F, it can be seen that both variables of product quality and religiosity simultanously affect the customers’ decision to keep theirfunds in BSM Branch of Purwokerto. Based on t test, it can be seen that independently, either variable of product quality or variables of religiosityinfluences the customers’ decision to keep their funds in BSM Branch of Purwokerto.
