Student's t-test

analysed and interpreted. Data 2.1 Research Stanford University found that on average, males outperform females on mathematics tests (Niederle & Vesterlund, 2010), which would be expected in the statistics course BSB123. The majority of the BSB123 sample (56.8%) was female, which may affect exam results. Additionally, quiz results are positively correlated with exam results (Wambuguh & Yonn-Brown, 2013) and students…

The article, “The Digit Span Backwards Task: Verbal and Visual Cognitive Strategies in Working Memory Assessment”, by Hilbert, Sven, Tristan T. Nakagawa, Patricia Puci, Alexandra Zech, and Markus Buhner, aims at investigating the differences in performance between visualizers and verbalizers cognitive strategies by using digit span backwards. The digit span backwards has been used for many decades to assess the working memory capacity. The concept of working memory initiates the way we are able…

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 Post-hoc tests displayed significant effect for visual versus acoustic; the…

had poor reliability (Cronbach 's = .59). After conducting an independent sample t test, our results indicate that Patriotism Composite Scale Score did not differ significantly between parental education, t(23) = 1.53, p > .05. Participants with parents who had a 4 year degree or lower had the same Patriotism Composite Scale Score (M = 3.76, SD = 1.12) as participants with parents who had a professional degree or above (M = 3.21, SD = 0.60). Additionally, another independent sample t test was…

notable point is that the above solutions depend only on bend factor(h), not on r/t and R/r. Equations (1-3) are applicable only for the pure in-plane bending moment and the effect of internal pressure is not taken in to account. Also these analytical solutions consider constant wall thickness along the contour of the pipe bend cross section. However, the most of the pipe bends are made using a forming process and as a result, have wall thickness variation along the surfaces of the pipe bend…

14(2) .http://dx.doi.org/10.1177/1474704916653964 Question 2: Describe the results of the practicum (2 marks) and critically discuss the results of the practicum in the context of previous evidence (2 marks). You should include at least 2 references (1 mark). Answer (max 250words): An independent sample t-test was conducted to compare evaluation in the neutral and deceiving conditions, t (117) = -.311, p= .779. An independent sample t-test was conducted to compare pain intensity in the neutral…

The descriptive analyses include different statistical methods, such as, Chi-Square, independent sample T-Test, Bivariate correlation, and Binary regression. The survey focuses primarily on the students’ spending, such as acquiring textbooks, living on campus vs. off campus, enrolling in the university’s meal plan, transportation costs, as well as any other costs that are important for the students’ needs and success during college. Since the respondents all come from different backgrounds,…

stronger internal reliability of .69 if item regarding academic concerns was excluded from the questionnaire. Furthermore, items associated with coping strategies reported consistent correlations throughout questionnaire with problem-focused strategies ranging from .78 to .65 and emotion-focused strategies ranging from .61 to .42. Hypothesis #1 examined the overall perceived stress levels between males and females. An independent sample t-test reported female undergraduate psychology…

inoculated on a 1 μM phosphate agar plate (Biology 108 Lab Manual 2015). There were 6 agar plates (Class groups) within each treatment group. Using sterile technique with a pasteur pipette, 1 seed per agar plate grid-line was inoculated for a total of 7 seeds per treatment. The agar plates were sealed, labeled, and incubated at room temperature for 2 weeks. Then, germination frequency and the quality of seedling development was determined in both groups. To control for possible growth…

There are different types of parametric tests to determine if a statistically significant difference is present. An independent-samples t-test is used when comparing two groups on one continuous dependent variable that is normally distributed. A paired-samples t-test is used when you look at the differences of one group across two time periods or observation periods. ANOVA tests are used when we are examining more than two groups or more than two observation periods. Slide 3: Our null…
