Dear Respectful Listers,
We are working on an analysis with ordinal data and are seeking your kind advice and help.
We have a questionnaire with 30 questions. Ten of them are designed and put under one section to assess the level of knowledge of farmers on an agricultural pest management technique. Each question under this section measure on 3 level (Yes, Maybe, No) and we plan to treat this as ordinal data corresponding to score of 3, 2, 1, respectively). With ten questions assessing preliminary knowledge of a sample of 100 farmers, we plan to test the correlation between their level of confidence on a Likert scale of 5 (ranging from 1 to 5) and the total scores under the section to assess knowledge (total maximun score for this ten-item section is 30 and minimum score is 10).
We are planning to use Goodman Kruskal Gamma test to test the trend of association between farmers knowledge (in terms of the knowledge level)and their confidence (in terms of ability to apply the knowledge). We also plan to user Spearman test to test the correlation.
Would it be possible for us to apply the above techniques? And there any better techniques that you would recommend?
Thank you so much for your kind help and support. And We are looking forwards to your help.
With our best regards,
Tu
