MANOVA PROJECT 2
Introduction
The study looks at three different ratings of the presentation; difficulty, usefulness, and
importance to determine if there is a difference in the modes of presentation. The major aim of
this study is to investigate whether the interactive website is superior because that is the most
cost-effective way of delivering the information
The study has applied the use of multivariate analysis of variance to meet the objective. A
multivariate analysis of variance (MANOVA) is a technique that applied to comparing
multivariate means. Multivariate analysis of variance is suitable for use in this study because the
variables are from different samples. Moreover, the study seeks to establish whether there is any
significant difference in the means of the groups (Srivastava, Kubokawa, & Tatsuya, 2013).
The data set consists of three groups (group 1, group 2 and group 3). The data sets meets the
assumptions that are necessary for conducting a multivariate analysis of variance (Srivastava,
Kubokawa, & Tatsuya, 2013). For example, the data set consists of three independent variables
which are measured in intervals. The three groups consist of categorical variables. There are no
outliers and the sample size is adequate to conduct a multivariate analysis of variance
(Sugasawa, Shonosuke, Kubokawa, & Tatsuya, 2017).

The table below outlines the output of the multivariate analysis of variance among the three
groups. Multivariate test investigates whether there is any significant difference in the average
values of the responses across the groups. The results have been obtained using SPSS. The
results indicate that the all the significant values are 0.00.
