Results: At the start of the experiment, the initial flow rate was established as 20 ml min-1. This means that there is a steady flow of fluid or blood in your body (in this case, water) at a rate of 20ml min-1. In order to find the final concentration of the Eosin (2,5 mg ml-1) in the “blood” after 60 minutes a calibration curve had to be created by making up seven different solutions of eosin (11,25 μg ml-1) and water to compare it against their absorbance that was calculated in a…

The present study investigated the possible relationship between self-defeating humor and the use of humor as a coping strategy. It also predicts that the use of humor as a coping strategy is negatively correlated with self-defeating humor Meaning, for example, if an individual has a lower self-defeating humor score, the lower the usage of humor as a coping strategy. However, the results of the present study do not support the idea of a negative correlation. Instead, there is a weak, but…

Total no. of problems correct (out of a possible 20): X Attitude toward test taking (out of a possible 100): Y (X - X ̅)² (Y - Y ̅)² (X-X ̅)(Y-Y ̅) 1 17 94 1.96 204.49 20.02 2 13 73 6.76 44.89 17.42 3 12 59 12.96 428.49 74.52 4 15 80 0.36 0.09 -0.18 5 16 93 0.16 176.89 5.32 6 14 85 2.56 28.09…

In the following two studies, Vrij and Mann (2001) and Mann, Vrij, and Bull (2004), respectively, researched police officers abilities to detect deception in real-life, high-stakes scenarios. They also looked at the behavioural cues which were used to come to these conclusions. In the first study by Vrij and Mann (2001), participants were comprised of 52 police officers in the Netherlands, 28 male and 24 female. The officers had an average age of 30, around 9 years of service, and rated…

Based on student responses from the questionnaire, students are spending significant amounts of time participating in extracurricular activities. Students are spending more time participating in arts, which includes band, orchestra, and fine arts and sports offered at middle school level like football, basketball, track and field, and swim. A substantial amount of students spent zero hours participating in extracurricular activities, seen in Figures 3 and 4. Figures 3 and 4 also demonstrate…

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…

Discussion This longitudinal study assessed the extent to which academic achievement and engagement were predicted from the academic achievement and engagement of friends and network members. Concurrent Relations As expected, adolescent’s academic achievement was highly correlated with that of their friends and network members. This is consistent with findings from U.S. studies. Ryan (2001) found that students’ academic levels were similar to group’s academic levels with the correlations…

Since the study was conducted in Texas of United States, the demographic distribution here may be different from other part or State of the country. Moreover, for the special locate of Texas, there are more Mexican immigrants or Mexican Americans, the racial differences may varied from any other state of the country. Furthermore, the participants were selected through convenient sampling instead of random sampling, which may not represent all the middle school students with different cultural…
