I am trying to compare a printed word dictionary with a digital dictionary that included added features like sound and video feedback. For this I have selected 60 participants and asked 5 questions (same general questions) with regards to printed and digital one. A likert scale was used to give points to these questions. Then I used Wilcoxon test to test the statistical significance. Is it a good design for a research? I have seen people using dividing respondents to control and experimental group and doing pre/post test design. I couldn't find a way of doing that for dictionary. I just want to know user preference of different features provided and to find whether digital one is better that printed one. Whether my design is ok?

  • $\begingroup$ Did you scramble/ randomly assign the order in which they tried the dictionaries? If so, you did a cross - over study and can Google for that. $\endgroup$ – Björn Mar 12 '18 at 5:55
  • $\begingroup$ @Björn No. But told the respondents that they need to compare both dictionaries before the start of the study. $\endgroup$ – user2721 Mar 12 '18 at 6:17
  • $\begingroup$ Paired Wilcoxon or something parameter $\endgroup$ – Björn Mar 12 '18 at 7:02
  • $\begingroup$ ....Something parametric with a random subject effect may be a reasonable choice then. $\endgroup$ – Björn Mar 12 '18 at 7:03
