Student's t-test

Independent Samples t-tests were completed to determine whether a difference exists between teacher and administrator perception as well as any differences between traditional and alternative certification pathway. This chapter continues with a description of the subjects,

Summary of respondents For the purpose of the study, the questionnaire was prepared to collect some background information of the participants in this survey. It will help to identify the respondents and how the samples seem to be. But for the reason of anonymity, there is no comprehensive information about respondents. It is agreed to make the respondents information in anonymous throughout the study, and not used any other purpose, other than academic. To achieve that purpose the questionnaire

Both developing and developed nations were part of the set. The developed nations consisted of 47% of the total set. We started with 43 nations and dropped a few countries later from the analysis because of missing data. 4. RESULTS AND ANALYSIS Table 2 shows the correlation results among various variables. Average service is correlated with all cultural dimensions, except for MF and the correlations are in predicted directions of hypotheses 1-3. The OLS regression results are shown in Table 3. Here

Analysis of variance is a statistical method used to test differences between two or more means. ANOVA is used to test general rather than specific differences among means. An ANOVA conducted on a design in which there is only one factor is called a one-way ANOVA. The One-Way ANOVA is considered an omnibus test because it indicates whether or not there are any significant differences in the means between any of the groups. However, it does not indicate which mean are different. The One-way ANOVA

Statistical Analysis: All the results were expressed as mean±SEM and subjected to One-way analysis of variance followed by dunnets test using GraphPad prism 5.0 Results : Effect on TC TC levels were significantly elevated in positive control when compared with normal control. When compare with normal control, standard group and ethanolic extract groups are significantly different (F = 25.20, p<0.01). Standard group, ethanolic extract, and aqueous extracts groups are not significant When compared

Difference Between Principal Preparation Programs Methods A t-test is used to evaluate statistically significant differences between two samples (Creighton, 2007). For this assignment, I tested the null hypothesis stating there is no significant difference between Principal Corps (PC) School Leaders Licensure Assessment (SLLA) scores and the SLLA scores of those enrolled in the Educational Leadership Principal Cohort program. To conduct my t-tests, I first downloaded the SLLA data for PC and Cohort participants

Another researcher presented how students who were struggling in school benefitted from a smaller classroom and this closed the achievement gap between students (Bosworth, 2014). Also, one study reported that class size had no effect when it came to a student’s performance when they were in middle school, but there is an effect when the students are in elementary school (Vaag, 2013). Students in a smaller class will have a higher grade compared to a students in a larger class. Method Participants Participants

Since then I have picked up the flute, the violin and the guitar along the way

Methods Participants 51 participants - some of which were undergraduate students attending Concordia College, currently enrolled in an introductory psychology course - completed an online questionnaire that measured both extraversion and conscientiousness. They rated these two traits in both themselves and their oldest or youngest sibling, depending on which they identify as. Youngest children rated the firstborns in their family, and firstborns rated the last borns. Our participants needed to either

one-sample t-test shows that this difference in mean age is significant, t(249) = 3.55, p &lt; .001. The 95% confidence interval indicates that since 1995 the average age of tourists has decreased by between 1.59 and 5.56 years. Contrary to expectations, the age of tourists in Katatonia has decreased since 1995. In a random sample of 250 tourists in Katatonia, the average age was 44.84 years (s = 9.96 years). While this is lower than the average age of 45 years recorded in 1995, a one-sample t-test
