Analysis of variance

Ethical Concerns Experimental design is a field whereby ethical concerns are almost always a top priority. Although most individuals see ethical norms as common sense, they often vary from culture to culture and there can be discrepancies in the interpretation even by members within a certain cultural group. Furthermore, it is vital to determine any potential ethical concerns contained within an experiment and address those concerns in order to reduce their potential impact on the results.…

There were 281 participants in this experimental study. Most of the participants were family or friends of students in a research methods class at Florida International University, and they were recruited through email, personal, or telephone request. One hundred ninety one participants were female (68%) and 90 were male (32%). They range from age 13 to 92 (M= 32.33, SD= 13.58). This included 63 Caucasian participants (22.4%), 56 African American participants (19.9%), 8 Asian participants (2.8%)…

Participants The participants for this digit span stud consisted of 3 subjects from a large public University. The participants comprised of 1 male and 2 female students with their age ranging from 18-21 years old. With regard to deficiencies, the male student reported that he has color-blindness, while the two female students did not report any deficiency. Apparatus This digit span experiment was conducted in the Social Sciences Laboratories at UCI. All three participants carried out the…

exposing participants to repeated measures. When analysing variance there are a number of assumptions which need to be considered and applied. Firstly, it is required that participants are selected at random to adequately represent the target population. Secondly, the data must be measured at an interval or ratio level (Pallant, 2010). It is also argued by Pallant (2010) that the population from…

Hypotheses H1: Increased emotional intensity of anti-tobacco video content will lead to significantly higher levels of skin conductance for narrative compared to non-narrative videos. H2: Increased emotional intensity of anti-tobacco video content will lead to significantly higher levels of corrugator facial EMG for narrative compared to non-narrative videos. H3: Increased emotional intensity of anti-tobacco video content will interact with narrative content such that: H3a: Cardiac deceleration…

A within subject’s experimental design, compared the perceived differences in length of different sized paperclips on different body parts. The perceived distance of the paperclips, were rated on a scale of 0 to 2; zero meaning equal, one meaning shorter and two meaning longer. There were three conditions; the Finger-Wrist condition, the Finger-Forearm condition, and the Wrist-Forearm condition. 20-psychology students participated in the study. All 20 participants participated in all three…

With political debates centering around greater environmental issues such as climate change, air pollution, and the alleged fifth mass-extinction, a dog-owner may wonder why signs saying “please pick up after your dog” are appearing more and more in neighborhoods and parks. However, with 83 million dogs in the US producing 10.6 million tons of poo a year (Freinkel 2014), a contributor to the intensification of these greater environmental issues is the methane produced by this waste and the…

The purpose of this study is to measure the differences between age in relation to risk-taking/impulsiveness and reaction time. The reason being, we are interested in figuring out whether or not younger adults are more prone to risk-taking and impulsiveness than the older adults are. Risk taking is an important form of human behavior that has been the subject of numerous investigations, scholarly analyses, and policy debates (Byrnes, 1998; Slovic, Lichtenstein, & Fischhoff, 1998). Risk-taking…

Hispanic or Latino. Measures This study was intended to be an experimental design. Therefore, there were two independent variables (factors) and one dependent variable for the two social media posts. Consequently, one 2x2 between subjects analysis of variance was run for the positive social media’s posts and for the negative social media posts…

Repeated Measures Analysis of Variance (RM-ANOVA) was conducted to compare the reaction time of visual and acoustic conditions (previously shown in study phase) with new brands (not presented before)(Graph 1). Mauchly’s test showed that the assumption of sphericity had not been violated, χ2 (2) = 0.68, p = .711. Degrees of freedom were corrected using Greenhouse-Geisser estimates of sphericity ( = .98). There was a significant effect of modality type, F (2, 60) = 20.09, p < .001. Bonferroni…
