 # What Is The Validity Of Agression Analysis

Good Essays
In this section, the analysis of validity includes three parts: validity of CSR measurement scale, validity of brand image measurement scale and validity of brand loyalty measurement scale. Based on the output of SPSS (details in Appendix F), we observed that there are three main steps to examine the validity. First, looking at the values of KMO and Bartlett's Test. Then, based on the Total Variance Explained table to determine the numbers of extracted factors. In the end, based on the Rotated Component Matrix table to observe the value of each variable factor loadings (a rule of thumb that factor loadings should greater than 0.30) to evaluate whether or not the extracted factors are consistent with the dimensions of the scales.
4.5.1 Validity of CSR scale
Firstly, after using the EFA method to analyze the 24 questions of the CSR part, we can see that the results of KMO and Bartlett's Test are shown in Appendix F: Output of validity analysis (CSR part). The KMO value is 0.896 (between 0.8 and 0.9), which falls into the range of being superb. The Bartlett's Test Chi-Square value is 1787.900 (df=276) and the significant level at 0.000, which means the R-matrix is not an identity matrix and. Therefore, these 24 questions suitable for factors analysis and there are some relationships between
After extraction, factor 1 accounts for 35.721% of variance (contributes to the most variance, as each successive factor will account for less and less variance), factor 2, factor 3 and factor 4 accounts for 7.759%, 5.660% and 5.342% respectively. Moreover, the eigenvalues of the factors after rotation are displayed at the column called “Rotation Sums of Squared Loadings” that factor 1 only makes up 5.338% of variance (compared to 2.691%, 2.618% and 2.428%

• In table 9 fixed asset turnover ratios of NIIT and 3i Infotech has been calculated. In 2010 NIIT had ratio of 2.42 whereas 3i Infotech had 0.22. Last year this ratio went to 1.89 in case of NIIT and in case of 3i Infotech it went to 0.12. 3i Infotech always had this ratio less than NIIT. From this it can be concluded that NIIT has been more effective in using the investment in fixed assets to generate revenues, than 3i…

This indicates that the means do not equal zero. A mean of differences was found to be 24.3216, with a 95 percent confidence interval from 1.7277 to 46.9155. The third t-test conducted was between the valid and neutral conditions, which was found significant [t(102)=4.9969, p<0.001]. A mean difference of 32.8711 was recorded, along with a 95 percent confidence interval between 19.8232 to…

The Freundlich model can be expressed as : .................................................................................................... (6) where qe mass of adsorbate is adsorbed per unit mass of adsorbent (mg/g), Ce is the equilibrium concentration of adsorbate (mg/l), Kf indicates adsorption capacity and n an intensity factor of the adsorption process , which varies with the heterogeneity of the adsorbent. The adsorption is better favorability when 1/n is to be grater. The fractional values of 1/n ranged between 0 and 1. The constants Kf and 1/n were calculated from the intercept and slope of the plot of ln qe versus ln Ce. Fig.10 shows the linear plot of Freundlich isotherm for adsorption of CV and MB onto fennel seeds.…

Emailtime and Wwwtime consisted of 320 and 317 valid cases, respectively. The mean for Emailtime was 383.99 minutes spent on email per week, whereas Wwwtime had a mean of 568.57 minutes per week. Interestingly, both displayed a large standard deviation, 595.13 minutes and 721.94 minutes, respectively. However, since the majority of respondents spent up to 200 minutes on email and up to 400 minutes on the Internet, with few participants exceeding 3,000 to 4,000 minutes a week, this is somewhat expected. Due to the clustering of scores to the left the skewness of the distribution was positive for both variables (2.70 for Emailtime and 2.72 for Wwwtime).…

(our data was combined into one index (i.e.customer service orientation)) Combining Likert scales into indexes adds values and variability to the data. If the assumptions of normality are met, analysis with parametric procedure can be followed. (Christopher and Elaine, 2007) Creswell(2008) further proposed that in order for Likert data to be regarded as interval data there is need to develop multiple categories within a scale (in our questionnaire, it was measuring counter-productivity, aggreeableness, conscientiousness, and emotion stability), establish equality of variance between each value on the scale and normality of the data. In Murray’s (2013) experiement, she used scale data from a study with 111 participants which measured the 5 variables (mathematics self-efficacy, academic self-regulation, availability of academic resources and learning styles). The study asked participants to choose the best fit answer from 3 different Likert 5 point scales.…

However, the closest contracts in the MAS method usually have shorter distance to the centroids. The 5000 contracts in each subset are also included in the whole portfolio X=(x ⃑_1,x ⃑_2,x ⃑_3,…,x ⃑_n), and it is possible that exists contracts with shorter distance to the centroids from other subsets. This impact on accuracy is tested in Table 4 and Table 5. For example, in Figure 2, if the centroid is denoted as C and the closest contract in the same subset is B. The contract with shortest distance to the centroid is denoted as A, but it is not divided into same subset.…

It is suitable for either numerical or categorical data (Table 2). It compares the means of 2 groups to determine if they are the same or not. It is two types (paired and independent t test). Analysis of variance F test is a generalization of the t test (or Wilcoxon or Mann-Whitney U test) when 3 or more groups are being compared. There are both parametric and nonparametric analyses of variance referred to as ANOVA by sum of squares or ANOVA by rank, respectively (Figure 2).…

Post-hoc comparisons using the Mauchly’s test of sphericity indicated that the mean score for condition one indicated that the morning condition (M=6.75, SD =2.33) was carried out was non sig and showed homogeneity of variance. As the day progressed the mean score increased in the afternoon condition (M=7.34, SD=1.98) and finally the highest mean scores were produced in the evening conation (M=9.00, SD=2.67). From this it can be identified that there was no significant…
