The Mann-Whitney U test is utilized to compare the variation between two independent groups when the dependent variable is continuous but not normally distributed. Our experts understand all the requirements for conducting the Mann-Whitney U test using SPSS, such as ensuring all assumptions are met before the test. Reach out today and enjoy our flawless services.

10. ANOVA (One-Way and Two-Way) Analysis in SPSS

Analysis of Variance (ANOVA) is a statistical method used to evaluate the difference between means with one dependent variable and multiple independent variables. Our statisticians conduct ANOVA analysis in SPSS to compare the means of two or more groups and determine if there is a significant difference. We assure our clients of reliable findings of their data by ensuring the normality and equal variance assumptions are met before performing ANOVA analysis using SPSS.

11. ANCOVA Analysis in SPSS

ANCOVA is an extension of ANOVA that has an added covariate, commonly used for the analysis of quasi-experimental studies. In the process of offering ANCOVA analysis services in SPSS, we provide expert help to our clients by combining the elements of regression and ANOVA to analyze the effect of the independent variable on the dependent variable while controlling for the covariate. We report the findings by illustrating the correlation coefficient and significant p-value and composing a summary table of the means of the dependent variable under research before and after the covariate adjustment.

12. MANOVA Analysis Using SPSS

MANOVA is a statistical method that is used to determine whether multiple levels of independent variables affect dependent variables. While conducting MANOVA analysis using SPSS, we ensure that the assumptions of homogeneity of variance, normality, and the absence of multicollinearity are met. We help our clients understand how various treatments influence multiple outcomes and how the intervention affects the dependent variable.

13. Correlation Analysis in SPSS

Correlation is a statistical analysis method conducted to measure the degree of association between two variables. Based on the customer’s research questions or objectives, our experts determine the type of correlation analysis in SPSS to perform. Some of the correlation coefficient analyses we conduct include (a). Pearson’s, (b). Spearman’s, and (c). Kendall. Our experts utilize Pearson correlation to evaluate the degree of the relationship between linearly related variables and Kendall correlation to compute the strength of dependence between variables.
