Prima facie, I see no statistical reason why not to use two groupings rather than five, if it makes more sense in your study. I would still argue that, on theoretical grounds, it’s still wrong to use such measures with ordinal data, but there are convincing arguments (including Liket’s own thesis) that a well-crafted scale (i.e., a composite of multiple items) will produce data that behave as if they are interval/continuous – so it makes practical sense. Afterwards, number one which is the least value in the scale was added in order to identify the maximum of this cell. Both scales produce ordinal data, so calculating their mean is problematic. 4-like much If you’re just doing descriptives, it should be ok. This doesn’t make sense when labelling all the options, as this clearly makes the data ordinal (or nominal). After describing the distribution of responses and their central tendency (mode/median), you would normally want to compare the two groups. Hello Iftikhar. An online survey tool, such as GoogleForms, can also be used to create online surveys and it will generate graphs and stats from your survey data - Likert style. 1 0.0036 Point Value Statistical Range Descriptive Rating (10+50)/2=30) using Wilcoxon signed-rank test. i want to analyse using the mean value.

By applying the Likert scale, survey administrators can simplify their survey data analysis. I have collected the data on a 5 point likert scale with 1 as never, 2 as rarely, 3 as sometimes, 4 as often and 5 as very often. plot(as.likert(x)) Both likert and plot.likert work by calling the as.likert function on their argument x.

Besides, as you will read in the blog post above, and in many statistics manuals, calculating the mean for Likert scales is dangerous statistical territory.

The questionnaire has 3 subscales measuring 3 dimensions of eating behaviour. Thanks. 2-slightly like To me this makes a lot of sense that an individual receives for example a score of 3,4 on intrinsic motivation. Does it make sense?

I like your comments. var domainroot="www.simplypsychology.org" Scales (1) and (2) are ordinal, because you can meaningfully place the values in a row from ‘least’ to ‘most’. However, you will likely need to estimate the central tendency and dispersion for each item: you can find some ideas here. they were measured on 1 to 6-point scale. there are 5 treatment groups (6 mice each group) are compared, 2 controlled groups (positive controlled and negative controlled) and 3 experimental groups (50%, 75%, 100% solution). I used a 3- point Likret scale (agree, disagree, uncertain) to measure attitudes towards writing. Norman argues that parametric procedures are robust enough to withstand violations of their assumptions. (2007). Now I would like to investigate if a higher cookie knowledge means a higher attitude toward retargeting and if age has an influence on this (e.g. Thank you so much. It is typically a five response category scale ranging from “strongly disagree” to “strongly agree”.The purpose of a Likert scale is to identify the attitude of people towards the given stimulus objects by asking them the extent to which they agree or disagree with them. Also, since we are dividing by N, would this be considered a mean? eval(ez_write_tag([[250,250],'simplypsychology_org-medrectangle-1','ezslot_7',199,'0','0']));report this ad, eval(ez_write_tag([[160,600],'simplypsychology_org-box-1','ezslot_2',197,'0','0']));report this ad, eval(ez_write_tag([[300,250],'simplypsychology_org-large-billboard-2','ezslot_6',618,'0','0']));report this ad, eval(ez_write_tag([[336,280],'simplypsychology_org-large-leaderboard-1','ezslot_3',152,'0','0']));report this ad, Likert Scale Definition, Examples and Analysis video, Two-component models of socially desirable responding, Essential Elements of Questionnaire Design and Development.
