Descriptive statistic is a statistic analysis to describe the characteristic of the respondents (Pallant, 2013). This study employs descriptive statistical analysis which gives value of mean, median and standard deviation of the respondents based on several indicators, such as sex/gender, educational level, position at work and income of the respondents. By using these indicators, the researcher describes the profile of the respondents. Hence, it can give some valuable information about the respondents. Furthermore, the descriptive statistic is not enough to answer the research questions and it should be followed by other analysis tools such as exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and structural equation modelling (SEM).
4.6.5 Exploratory Factor Analysis (EFA)

According to Hair et al. (2010), there are two types of factor analysis, including exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The CFA is a technique for testing the hypothesis about the degree to which the data meet the hypothesised factor. On the other hand, the Exploratory Factor Analysis (EFA) is a data reduction technique (Pallant, 2013). In other words, EFA is a multivariate statistical method to summarisation and data reduction (Hair et al., 2010). The EFA is different with other techniques such as regression and analysis of variance. This technique is an interdependence technique which is not categorised as dependent and independent variables. This study employs SPSS 22 as the software programme to run the exploratory factor analysis. There are some procedures in conducting EFA in this study (Pallant, 2013).
First, this study assesses the suitability of the data for factor analysis. In this step, the n...

...e hypotheses testing and see the regression weight of the construct’s relationships. However, when the structural model is not fit, there are some ways to improve the model such as using the modification indices and standardised residuals of variance which should be less than 2.58 (Byrne, 2010).

4.6.11 Test of Indirect Relationship

Beside the direct relationship between each variable, this study also examines indirect relationship of some variables. Consequently, to test those relationships this study needs more analysis. According to Baron and Kenny (1986), there are two indirect relationships between variables, including moderating effect and mediating effect. Especially to test the mediating effect of a variable, they argue it can be tested by using the Sobel’s test. Hence, this study uses the Sobel’s test to examine the indirect relationship between variables.

Univariate Analysis Is The Simplest Form Of Quantitative Essay

- Univariate analysis is the simplest form of quantitative (statistical) analysis. Univariate analysis explores each variable in a data set, separately. It looks at the range of values, as well as the central tendency of the values. It describes the pattern of response to the variable and also describes each variable on its own. Univariate analysis was performed so as to facilitate more complicated analyses, like bivariate and multivariate analysis. Univariate descriptive statistics describe individual variables....   [tags: Regression analysis, Statistics, Linear regression]

Descriptive Statistics Can Be Defined As Statistics Essay

- INTRODUCTION Descriptive statistics can be defined as statistics that summarizes data that is collected from a research. One way of summarizing research data is by calculating the measure of central tendency. Examples of measure of central tendency includes mode, mean and Midian. Data can also be summarized in respect to variance. When the scores are more spread out of the mean, there is a greater variance.

Descriptive Statistics: Raw Data Essay

- Several things can be done to the raw data in order to see what they can say about the hypotheses (Neuman, 2003). An inspection of the raw data can be done by using the descriptive statistics to find obvious coding errors. The minimum and maximum values for each variable must fall within the admissible range. Pairwise correlations depict that all relationships must be in the expected direction. Meanwhile, listwise deletion of missing values indicates that the data can be used for analysis. An outlier is an observation that is unusually small or large....   [tags: Data Analysis, Standard Deviation, Variance]

Essay on Statistical Methods in Quality Management: Descriptive Statistics

- Quality management frequently uses statistical methods to identify the existence of a quality problem and to analyze the root cause of the problem. Statistical methods require the collection of numerical data related to a process under investigation. The data can then be used to identify trends that can affect quality such as the rate of variance in the outcomes of a production process. The descriptive or inferential analysis of the statistical methods can also provide information about the most likely causes of the problem....   [tags: histogram, inferencial statistics, data]
