Wilcoxon Signed-Rank Test in SPSS The Wilcoxon Signed-Rank test is a non-parametric test that is equivalent of the paired t test. The Wilcoxon Signed-Rank test has the following hypotheses. Null hypothesis: Median of the population of differences between the paired data is zero. Alternative hypothesis: Median of the population of differences between the paired data […]
Spearman rank correlation coefficient in SPSS Spearman correlation coefficient is a nonparametric measure of rank correlation. It measures the strength and direction of the association between two ranked variables. Assumptions Two variables should be continuous. Two variables should represent paired observations. There should be a monotonic relationship between two variables. A monotonic relationship exists either […]
SEM Moderation Model in Smart PLS Theoretical model developed by a study is tested using Structural Equation Modelling (SEM). SEM is capable of testing complicated relationships among variables. Moderation analysis tests the influence of a third variable on the relationship between independent variables and dependent variables. Here, job characteristic is considered as exogenous (independent) variable, job […]
SEM Model in Smart PLS Theoretical model developed by the study is tested using Structural Equation Modelling (SEM). SEM is capable of testing complicated relationships among variables. Here, Job characteristic is considered as an exogenous (independent) variable and Job satisfaction is considered as an endogenous (dependent) variable. The relationship between the exogenous and endogenous variables […]
SEM Mediation Model in Smart PLS Theoretical model developed by the study is tested using Structural Equation Modelling (SEM). SEM is capable of testing complicated relationships among variables. An intermediate variable, called the mediator, is considered in mediation. Here, Job Characteristic is considered as an exogenous (independent) variable, Job Satisfaction is considered as an endogenous […]
Reliability analysis in SPSS Cronbach’s alpha is a common measure of internal consistency. It is commonly used to determine if the scale is reliable or not when the questionnaire is developed based on multiple Likert scale statements. A researcher developed a questionnaire to identify the challenges faced by students in an educational institution. Questions were […]
Pearson Correlation in SPSS Pearson Correlation is a parametric measure that produces a sample correlation coefficient, which measures the strength and direction of linear relationships among pairs of continuous variables. Pearson Correlation is also called as Pearson Product-Moment Correlation (PPMC). Assumptions Two variables should be continuous. There should be a linear relationship between the two […]
One Way ANCOVA in SPSS One-Way ANCOVA is a statistical test used to determine if three or more groups of variables of interest are significantly different from each other, while accounting for the effect of another variable termed as a covariate. Assumption Dependent variable and covariate variable(s) should be measured on a continuous scale. Independent […]
One-Way ANOVA in SPSS One-Way Analysis of Variance (ANOVA) is used to determine whether there are any statistically significant differences among the means of three or more independent groups. One-Way ANOVA has the following hypothesis. Null hypothesis: µ1 = µ2 = µ3 …µk (k is the number of independent comparison groups) Alternative hypothesis: All means […]
Multiple Regression Analysis in SPSS Multiple regression analysis is an extension of simple linear regression. It is used when the value of a variable needs to be predicted based on the value of two or more other variables. Assumptions Dependent variable should be continuous Two or more independent variables, which can be either continuous or […]
