Learn about factor analysis - a simple way to condense the data in many variables into a just a few variables.
2. Multiple question types Some website survey tools limit you to asking only multiple-choice and open-ended questions. But there are also other useful types of surveys, like Linkert scale NPS Smiley scale Checkboxes Forms (helpful in collecting contact emails and in lead generation) Hint: Loo...
In the used example: if in a test the original has a conversion of 4% and he alternative 5%, then 2,800 cases per group would be necessary to reach statistical significance. This can be demonstrated with the accompanying spss syntax (limit at significant test result.sps). These sort of ...
Since 2012, the UTAUT2 model has been widely used to analyse different types of users and organizations, as well as different types of technologies (Tamilmani et al., 2021). Therefore, this study adopts UTAUT2 model to investigate the use intention of robotaxi users. The hypotheses proposed ...
Hence, acquiring a more detailed examination of repair processes helps to analyse their pivotal elements. This, in turn, facilitates the identification of priorities for optimising repair procedures and provides guidance to repair service providers for process improvement. However, to date there is a ...
In recent years several external tools have matured sufficiently to analyse diverse sets of trajectory data from several simulation packages. Below is a short list of tools that are known to be able to analyse |Gromacs| trajectory data. * `MDTraj <http://mdtraj.org/latest/index.html>`__ *...
As you fitregressionmodels, you might need to make a choice between linear and nonlinear regression models. The field ofstatisticscan be weird. Despite their names, both forms of regression can fit curvature in your data. So, how do you choose? In this blog post, I show you how to choos...
It consisted of 29 multiple-choice and one-option questions organised into three sections. A total of 6,483 valid responses were received. Statistical Package for Social Sciences (SPSS) version 25.0 was used to analyse the survey results.Findings - According to the survey findings, food safety ...
The delta-delta Ct method, also known as the 2–∆∆Ctmethod, is a simple formula used in order to calculate the relative fold gene expression of samples when performing real-time polymerase chain reaction (also known as qPCR). The method was devised by Kenneth Livak and Thomas Schmittgen...
Percentage responses to mixed assessment questions which did not sum up to 100% were scaled accordingly. The correlation between students’ perception and assessment methods was analysed by using spearman’s rho. The cumulative link mixed model has been used to analyse the students’ assessment ...
