Chi-square tests 1. INTRODUCTION 1.1 χ2 distribution and its properties A chi-square (χ2) distribution is a set of density curves with each curve described by its degree of freedom (df). The distribution have the following properties: - Area under the curve = 1 - All χ2 values are positive i.e. the curve begins from 0 (except for df=1) increases to a peak and decreases towards 0 as its asymptote - The curve is skewed to the right‚ and as the degree of freedom increases‚ the

research questions should seek to discover what plausible courses of action are avaible for management to correct the problem at hand. Coming up with research questions can be challenging. Some of the problems with developing research questions is determing what area to focus on (Kinmond‚ K. (2012). Obviously the focus is on how to increase membership‚ but in this focus there could be a multitude of options to consider. Here are some research questions I would pose. 1) What are the factors contributing

Charles Edward Spearman (1863-1945) studied psychology in Germany and received his PhD at Leipzig. Spearman is noted as a pioneer in psychology and believed in the two-factor theory of intelligence. He wrote his first paper outlining this theory in 1904 with Bernard Hart (Gregory‚ 1987). Spearman claimed that testing a persons abilites to complete tasks against expected outcomes could be measured and expressed in a mathemactical formula‚ that mathematical formula is now known as the Tetrad Equation

Physics In Our Everyday Life Physics is not something that only knowledgeable scientist think about because physics coincides with our everyday life. They consist of energy‚ kinetic energy‚ potential energy‚ conservation of energy‚ velocity‚ acceleration‚ mass‚ force‚ and gravity. Fist there is energy. You need to go to bed early so you will have energy in the morning to go to school. Energy gives you the e ability to do work. Energy is everywhere in nature‚ sunlight wind‚ water

ANALYSIS On the first part of the experiment which is the determination of specific heat of metals. The obtained value of experimental specific heat of metal of aluminum and copper are 0.2152 calg-℃ and 0.0958 cal g-℃ ‚ respectively. It is a must to work faster in performing this experiment because working in an air-conditioned room greatly affects the result of the temperature. For the temperature values‚ the final temperature of mixture should not increase more than 1 ℃ compare
