that chains of historical events were fortuitously coincided. However, his opinion did not consider the repeatability of recession and the similarity of economic issues. Also, others claimed theories based on banking crises and failure of the gold standard. The book, The World in Depression 1929-1939 by Kindleberger, stated the reasons that the global Great Depression became a long term event. Britain lost their guarantor position in the global economy and currency system. Thus, the United…

Explore Correlation and Regression Using the explore function within SPSS gives a clearer view of how the data is represented. The explore function helps to assess the variables within the investigation by visually identifying various aspects of the data, therefor revealing the true nature of the data (Field, 2013). For example, the data in the Chamorro-Premuzic.sav file can be evaluated in a number of ways, for example analyzing the data based on the gender grouping allow one to visualize the…

learning objectives through practical exercises of the course. The journey began with descriptive statistics; measures of central location and dispersion. The very common measure of central tendency; mean, median and mode. Whereas variance and standard deviation were discussed as measure of dispersion. I 'm also actively participated in doing the exercises for both measure of central tendency and dispersion using hypothetical data given with the lecture. Furthermore, the lecture continue with…

descriptive statistics. These measures define the methods of summarizing a group of data by describing how spread out the data is. To describe this spread, a number of statistics are available, which are range, quartiles, absolute deviation, variance and standard deviation. Units of Enumeration These are units which data is collected in terms production of cloth - meters, weight-tons, time - hours. Units of collection and Enumeration are of three types. a) Single units : it represents single…

The effect of in or out-group membership of a critic on personality sensitivity Daniel Middleton Abstract Background Group membership creates a social identity that results in in-group favourtism, as a result in-group members distrust out-group members. However, little research has been conducted into the threat that arises from whether criticism is from an in-group or an out-group member. Aim The aim of this study was to compare personality sensitivity perception…

Pre-Lab Questions 1. A population is a group of the same species that live in the same area and sometimes compete or can mutually benefit one another. A group of organisms will only be considered a population if they live in the same area in space and time. N is the true population size for a given group of organisms. This number is unlikely to be completely known. Whereas N hat is an estimate of population size. 2. There are two methods of sampling, direct and indirect. Direct sampling is an…

Problem 1.17 In problem 1.17, the average age of pinon trees in the coast ranges of California was investigated. 500 ten-hectare plots randomly selected using a computer. The age of every pinon tree within each plot was measured and the average age of the plot was used as the unit measurement (Whitlock and Schluter, 2015, pg 20). The results of this investigation were used to estimate the average age of California pinon pines, making the population of interest in this study is all California…

For example, if σ = 45% and ρ = 0.2, then the standard deviation with 50 stocks would be 20.91%, and would rise to 22.05% when only 20 stocks are held. Such an increase might be acceptable if the expected return is increased sufficiently. Hennessy could contain the increase in risk by making sure that he maintains reasonable diversification among the 20 stocks that remain in his portfolio. This entails maintaining a low correlation among the remaining stocks. For example, in part (a), with ρ = 0…

Imagery ability A pre-experiment questionnaire was administered to establish the participants’ imagery ability prior to the imagery intervention. Questions focused on how easy it is for the participant to image and the vividness of these images. For example, how easy is it for the participants to image staying positive after setbacks. This helped to control for potential confounding variables as research has shown imagery ability influences the effectiveness of imagery (Gregg, Hall, McGowan, &…

Standard Oil was the leading supplier of oil to the United States in the 1880’s. The Company was run by John D. Rockefeller. Rockefeller became one of the richest and most powerful men in America. Rockefeller tried to get Standard Oil to be the only supplier of oil in North America.
