identify the missing piece to replace the answers

I've heard arguments that this type of data is interval data.

If the rate is low, even a big difference between Rs and NRs may not matter. - For such inference for a finite population, the study of "response propensity" groups is often recommended. I'm not convinced that decennial Census data are necessarily accurate for disadvantaged strata—for example the poor, the sick, or criminals (samples often studied in medical and social sciences), or over increasing time post-Census.Regarding item non-response, in medical articles discussion of incomplete patient records, particularly in the field of adverse drug reactions, is quite common—but imputation is not performed. I would suggest you still include them but you have to be transparent in your presentation of results by including the percentage of respondents that has skipped answering (some survey's includes don't know the answer/decline to answer to make sure no missing responses in the returns). Also, we're primarily trained from a design-based perspective on weighting and adjustment issues. Apparently there are a lot of beginning researchers who have learned how to use Likert-style items in questionnaires, but never got any advice about how to analyze the resulting data.Hence, I would like to put together a thread here that people can refer to whenever this question gets asked.Please remember that this is advice for beginning researchers who generally want to run basic regressions, so there is no point in recommending complex procedures such as Item Response theory or Structural Equation Modeling.Instead, I would to find sources for things like how to use Cronbach's alpha effectively and how to do the most straightforward kind of Factor Analyses (almost certainly Exploratory rather than Confirmatory).The overall goal is to help beginners get started with scaling, so who can suggest some resources?Using a parallel design mixed method approach combining the use of standardised measures of positive psychology constructs such as sense-of-coherence, hardiness, self-efficacy and locus of control and open-ended survey questions, the present study was aimed at exploring factors at play during the screening and selection of a South African (SA) spec...Join ResearchGate to find the people and research you need to help your work.© 2008-2020 ResearchGate GmbH. Just to share per the discussion, the link below is to the only paper I've ever written on imputation, and it was just an applied test (not a simulation). In arguably the best work of NASA--the Apollo 13 mission, the directive was "let's not make things worse by guessing."

The good side of this is that you can maximize the margin of error into your final analyses (which would affect the confidence interval of the statistics if sample size is too small). Main reason for reporting missing values in descriptive/bovariate analysis is that they have their own background and theory.

But it can work the other way (Difference between Rs and NRs isn't huge, but the missing data rate is high enough that creates NR bias).
