The portal provides the assistance in hypothesis testing using SPSS in downloadable PDF format.
If you are getting confused with lots of questions and doubts that are making you slow in your research, then the portal is with you to assist you at every stage of your research.
Let’s share our views, experience, questions & answers. Lets help each other in this “RESEARCH ” world.
Statistical Hypothesis testing is a widely accepted and proved statistical decision making tool. Both parametric and non-parametric tests are used to analyze the collected data.
An earnest attempt is made through this portal to provide a complete guide to understand the statistical tests with hypothesis testing. The basic purpose is to give the reader a sound knowledge about Hypothesis Testing survey research using SPSS. It is designed as a reference for the students of social science branches who are doing research as the part of their studies.Using SPSS for social research helps readers how to use SPSS software in statistical data analysis.
The Portal is intended to give the readers a very basic understanding on Hypothesis testing and how to use SPSS for statistical researches.

DISCRIMINANT ANALYSIS Introduction Discriminant Analysis undertakes the same task as multiple linear regressions with metric data. But in many cases we have to use categorical variables, such as loyality and disloyality, users and non users, buyers and non buyers of a product etc. Discriminant analysis is successfully used in these cases to find out the Read more about DISCRIMINANT ANALYSIS[…]
MULTIDIMENSIONAL SCALING TECHNIQUE Introduction Multidimensional scaling is a powerful statistical technique used for representing the preferences of respondents into the groups of ‘Dimensions and Map’. MDS is useful in measuring the perception and distinctive images of the stimuli used in research. Perceived relationships among stimuli are then represented by means of a visual display using Read more about MULTIDIMENSIONAL SCALING TECHNIQUE[…]

These groups are called clusters. It is not necessary that the clusters should comprise of people only, there could be clusters of brands, products Read more about CLUSTER ANALYSIS[…]
FACTOR ANALYSIS Introduction Factor analysis is used when the research problem involves a large number of variables making the analysis and interpretation of the problem difficult. The factor analysis helps the researcher to reduce a number of variables to be analyzed, thereby making the analysis easier. In factor analysis certain variables are combined into specific Read more about FACTOR ANALYSIS[…]
MULTIPLE REGRESSION ANALYSIS Introduction Multiple Regression analysis attempts to study the relationship between a dependent variable and a set of independent variables (one or more). It is a statistical technique that allows us to predict someone’s score on one variable on the basis of their scores on several other variables. When using multiple regression the Read more about MULTIPLE REGRESSION ANALYSIS[…]
WILCOXON SIGNED RANK TEST FOR PAIRED SAMPLE Introduction Mann Whitney U test assumes the samples to be independent of each other. But, the condition may not hold in reality; as in many cases the sample observations seem to be related pair wise. Wilcoxon signed rank test is used to test the equality of population means Read more about WILCOXON SIGNED RANK TEST FOR PAIRED SAMPLE[…]
MANN-WHITNEY TEST OR U TEST INTRODUCTION The test is used to examine whether two samples have been drawn from the same population or not. This test is an alternative to‘t’ test for testing the equality of means of two independent samples; provided the samples are small (sample size is maximum 30). It is a widely Read more about MANN-WHITNEY TEST OR U TEST[…]
FRIEDMAN’S TEST INTRODUCTION Friedman’s Test is an extension of the Wilcoxon test. Wilcoxon test can be applied to repeated-measures data if participants are assessed on two occasions or matched in pairs. In contrast, Friedman’s Test allows the analysis for the same sample of data assessed on two or more occasions or conditions or matched-subjects. It Read more about FRIEDMAN’S TEST[…]
