At the first step it was difficult to know how much of the HH income comes from adoption of different technology or a combination of it. Do you think we should assign numerical values to the scale data before using the tests of statistical significance?

A Likert scale, on the other hand, is composed of a series of four or more Likert-type items that are combined into a single composite score/variable during the data analysis process. Q10_7 = IV (reporting likert score from 1-5) Q10_8 = IV (manager likert score from 1-5) My guess is that you need to use an ordered logistic regression model but i'm not sure what to factor in my formula just the DV or everything? Likert calls people in more than one group "linking pins". If you have non-Likert scale DV items, you use the same process. Osborn, in Encyclopedia of Body Image and Human Appearance, 2012. These Likert-type variables are sometimes used in ordinary least-squares regression analysis. Participative. It uses a likert scale for all items — typically on a 5 or 7 point system using the following items: I have two sets of Likert data on a scale from 0 - 100 where 0 is strongly disagree and 100 is strongly agree.
