In this work, an orthogonal array experimental design was used to optimize the synthesis of a photocatalyst. This chapter provides the reader a crucial foundation for understanding the terminology and practical use of design of experiments (DOE). The practical use of this, as will be discussed later in this work, is that wise use of DOE can drastically reduce the time and effort to optimize procedures, catalyst synthesis or otherwise. In this section, we explore some of the general procedures of
shows the output of the ANOVA analysis and whether we have a statistically significant difference between the group means. We can see that the significance level for Att is 0.00 and 0.827 for Attnew. When this value is below 0.05, it means that there is a significant difference between the two means. When it is more than 0.05 there is no or little statistical difference between the two means. Hence for Attnew, there is a difference in the demand of cars but there is no difference in the Att case (Hussain
study used the factor scores (which are not ordinal or nominal scales) yielded by the factor analysis for the further statistical analysis. Therefore, the parametric tests could be proper techniques to test the difference between the respondents’ demographic groups regarding the SECI and innovation activities in the Egyptian banks. In this term, there are two parametric statistical techniq... ... middle of paper ... ...the males and females staff in terms of performing theses processes in the
In our study, there is a statistical significance between religion and practice of personal hygiene (P value is 0.025). The students belonging to Christian religion (40.70%) were following good practice of personal hygiene as compared to other two religion 21.00% (Hindu) and 31.70% (Muslim) respectively (Table no.11). There is no such comparison in other available studies. In our study, 100% of children were washing their hands before taking food. Maximum of 92.5% of students washed their hand with
Introduction Numerous experiments have been conducted to analyze the influence of ethanol on different sections of the human brain and how different concentration levels affect behavior. For example, it has been observed that excessive amounts of ethanol affect the cerebellum. As we know, the cerebellum controls balance and coordination, but when exposed to excessive amounts of ethanol, an individual is more prone to lose balance. Furthermore, the hippocampus, a part of the brain associated
constraints of valerian as an insomnia medication have reached varied and conflicting results. Though some studies have found valerian to have a subjective mild sedative effect in improving sleep,3 others have found there to be no objective statistical significance between valerian and placebo.5 Similarly, some research revealed that valerian reduced objective sleep latency when provided for an acute period of 3 days,4 while one study discovered that it takes about 2-3 weeks before valerian effectively
There are clearly differences in the way men and women think. Many studies show that neurons are packed closer together in women’s brain, and according to psychologist Sandra Witelson, this may be one reason why women are better at language and communication skills than men (Edmonds, 2003). But are there also differences in the way men and women perceive things? Are women faster at noticing change? Or do they pay more attention to visual details? If yes, then shouldn’t systems be designed to pertain
The Elementary Reading Attitude Survey (ERAS) / © PAWS survey designed by Dennis J. Kear from Wichita State University will be used in conducting this study. It provides a suggestion of student attitudes toward reading. The survey consists of twenty items and can be administered to the entire classroom in within ten minutes. Jim David, the creator of the Garfield cartoon character, and Paws Incorporated, the copyright owner, supplied camera-ready pictures of Garfield displaying a range of emotions
Studies of the disease were found by using the Texas A&M Corpus Christi library through electronic search of temporal lobe epilepsy. Four primary research and one review article were used to complete this literature analysis. The articles discussed are condensed in Table 1. Regarding EI in patients with TLE and patients with extra temporal lobe epilepsy was a case-control study that had three groups. Group 1 consisted of forty patients with TLE. Group 2 consisted of thirty patients with extra temporal
Peer-Assisted Learning Strategies (K-PALS) for students with disabilities. Additionally it looked to see if there was a correlation between the amount of training the teacher received and the students’ success. The team of authors used a variety of statistical methods to determine the effectiveness in both of these areas. A random group of 89 kindergartners, from 47 different classrooms in Minnesota schools all with individualized education programs, were divided into three different test groups. These
Humans are curious creatures who may very well feel the urge to disregard exact orders. This drive is often encouraged by feelings of boredom or often because we cannot limit ourselves to more knowledge. The objective of this study was to observe curiosity between males and females. We evaluated female “peekers” against male “peekers” and female “non-peekers” against male “non-peekers.” A box visible enough to get attention from participants was decorated, a hole was cut on the top and a sign was
This study looked at the role of sports in inhibiting the development of early social anxiety symptoms in children between 7 and 8 years old. With multiple hypotheses the researchers hoped to show that exercise and sports will have an anti-anxiety effect on this specific (social) form of anxiety. The specific hypothesis were as follows: children who participate in extracurricular sports should have less social anxiety symptoms one year later than a child practicing no sports, children on a team sport
On Tuesday in lab, we wanted to measure the velocity and acceleration of a ball rolling down an incline. To do this, we made our table have an incline by putting wood blocks under two legs of the table. We placed meter sticks on a table so we could determine the distance the ball traveled for a certain amount of time. We placed the ball at the 0cm mark on the meter stick and let go of the ball so it could roll down the table. To make our results more accurate, we videoed the ball rolling down the
This experiment would be considered a fair test as the variables were controlled; the same ball in the same condition was used, it was dropped from the same height each time, no additional external force acted upon it and the accuracy of the readings were consistent. However there were a few minor elements which may have altered the results such the test no being done on the different days. This would have had a minor effect as the temperature alters the elasticity of rubber and causes wood and concrete
A. Purpose of the Study “Reading is the motivated and fluent coordination of word recognition and comprehension” (Leipzig 2001). In the educational system, pupils are encourage to read books because of the belief that one becomes better at a skill based on the amount of time dedicated to that particular skill. Pupils must practice the skill learned and receive “frequent feedback (Samuel and Wu).” Practice is most effectual when it is individualized and accompanied with instruction (Renaissance
In the case study I am asked the major differences between public and private sector labor relations. Throughout my research I will use the text along with outside sources to help in finding the significant differences between the two. Furthermore as outlined in the text of (Holley, Jennings, & Wolters, 2012) have indicated some of the major differences between public and private sector including the market economy such as the relationship between the budget and the bargaining process, employee rights
Money is a major driving force in our lives, and people will often act in immoral and exploitative ways to acquire it. This money-immorality association is well established in psychological research, with results consistently showing that subjects who are primed to think about money are later more likely to lie, cheat and steal than the subjects who were thinking about other factors. However, the study performed by Francesca Gino and Cassie Mogilner suggests that it is not necessarily money – or
The Effect of Homophone Training on Pseudohomophone Reaction Time Abstract The study investigated the effect of training with homophones on the pseudohomophone effect when participants were required to search their lexicon for a familiar letter string, this also investigated the ideas put forward by the dual route model where orthographic and phonological processes are both used in the analysis of word strings. The design of the experiment was a between subjects forced choice lexical
False memory occurs when an event that never happened is remembered or it differs from reality. This effect can be created using a Deese-Roediger-McDermott (DRM) list. Each list contains 12 words associated with each other, and a critical non-presented word (CNPW) or lure word. Following the presentation of a DRM list, a recognition test shows that participants claim to confidently remember the lure word in great detail, although it was not presented. According to the spreading activation theory
The Effect of Hypnosis on Eyewitness Testimony Works Cited Missing Under hypnosis an eyewitness could produce false information whist giving a statement to the police. This is because one of the characteristic of being hypnotised is being sensitive to suggestion. Therefore the witness can give suggestive information through leading question (even if this isn't intended). It could lead to an alteration of the existing true memory. Although hypnosis might produce increased recall, it also produces
