Likert Scale Survey: from googleform to #rstats graph

Posted on by melliferrari

Many Biology students are interested in science communication or the public understanding of science and undertake projects in these areas.

They often conduct surveys which include Likert-scale questions.

This workflow will teach you how to set up a Google Forms survey with Likert scale questions, read the responses in to R and report on the results.

It uses the packages googlesheets (Bryan and Zhao, 2018) and likert (Bryer and Speerschneider, 2016).

These slides take you through the process.

  1. Really very useful! Got a ton of forms with likert data I just visualized per response. The workflow is so convenient, I’m going to go over them and see how much more can be done.

    Thanks for this!

    In likert(coloursurveydf) :
    items parameter contains non-factors. Will convert to factors

    1. I would guess that you might have a typo in the variable names in the code on slide 16. Also check that you used back ticks ( ` ) not ( ‘ )
      Check what is in coloursurveydf with
      str(coloursurveydf)
      You should have only the four variables. Additional variables would be created if the name just inside mutate isn’t the same as the one just inside factor in each case

  8. sorry but thie error comes again and again
    can you please help as I want to make likert charts on my scientific survey data, thanks.
    or can you please post he R commands so that I can check, thanks
