I have a doubt how to assess the statistical difference between ,,products. For my MSc thesis I had to ask people how they perceive the texture of some food products, both via two online surveys and a sensory test. These were performed via CATA method. differsmber of participants differ between the online and sensory and also within products (e.g. 64 people evaluated apple in the online and 20 in the sensory, 62 evaluated mozzarella online and 19 in the sensory test). I have now two contingency tables presenting the number of selections: example dataset

What I want to do is to assess if there is a statistical difference between the same product (e.g. apple) online vs sensory. Do you have any suggestions on how to do it (considering also the error correction)?

  • * the attributes used in both the tests are the same. – Luca Jul 22 '22 at 13:07
  • * the difference I need is according to a product and all the attributes together – Luca Jul 22 '22 at 13:07
  • This doesn't appear to be a specific programming question that's appropriate for Stack Overflow. If you have questions about analyzing your data, you should ask for statistical advice at [stats.se] instead. You are more likely to get better answers there. – MrFlick Jul 22 '22 at 13:13
