Statistical analysis of experimental data collected through a questionnaire with multiple answers within quant analytics

Statistical analysis of experimental data collected through a questionnaire with multiple answers within quant analytics

 

In this multiple answers are allowed, so i am having more than one answer per sample. How the data should be treated and calculate statistical significant levels.

Actually first things to do when you conduct the experiment is you have to decide what kind of design experiment that fits your problem. Design experiment will determine how your data will be analyzed.

The format of the questionnaire is hiding the obvious… just treat each response option as it’s own dichotomous (selected / not selected) variable and you’ll have no problems with your analyses.

 

You can then look at between-group differences, correlations, perform cluster analyses… whatever best

Please, how could we analyse the groups? in which things could we rely on for deducing correlations

Quant opinion: Do you think Statistical Analysis work can be outsourced to expert statisticians?

It’s a big “it depends”. Give more info on your environment/study/conditions.

Yes, certainly, under the right conditions. We offer data management and statistics analysis as a service (www.symbolix.com.au) and have found that demand for detailed analytics and statistics has grown in the last few years, particularly in areas like environmental impact assessment, business analytics/optimisation and with big public data sets.

The challenge, when looking to outsource any technical requirement like this, is to ensure that the contractor/consultant has a strong technical knowledge (obviously) but also a sense of the business requirements that you have. Business/Industrial statistics often has to compile data from multiple sources and the outcomes are much more focussed around achieving real insight for decision making and relies on a lot of exploratory data analysis tools backed up by inferential rigour. Good technical communication and visualisation skills are really important too.
