#Likert scale response options software

Seven-point Likert scales appear to be sensitive enough to record a more accurate evaluation of an interface while remaining relatively compact.Interpolations provide evidence that 5-point Likert scales may not be sensitive enough to record a usability test participantвЂ™s true evaluation of a system.Interpolations are problematic because they cannot be mitigated within an electronic survey medium and require interpretation with facilitated surveys.Five-point Likert scales are more likely than 7-point scales to elicit interpolations in usability inventories.The following are the main findings of this study: This finding supported the conclusion that 7-point Likert items provide a more accurate measure of a participantвЂ™s true evaluation and are more appropriate for electronically-distributed and otherwise unsupervised usability questionnaires. In an applied setting, this implied that electronic radio-button style survey tools using 5-point items might not be accurately measuring participant responses. Participants in the 5-point scale condition were more likely than those presented with the 7-point scale to interpolate, i.e., attempt a response between two discrete values presented to them. The original instrument with its 5-point Likert items was presented, as well as an alternate version modified with 7-point Likert items.

Overall I may be getting a little confused by the exploratory nature of this study in comparison to the experimental studies I am used to undertaking.A series of usability tests was run on two enterprise software applications, followed by verbal administration of the System Usability Scale. I believe this may result in assumptions of normality being violated so I may need to use nonparametric equivalents. The part where it becomes really tricky here for me is that some participants exclusively responded in the first condition, some participants exclusively responded in the second condition, and some participants responded in both conditions. And additionally presented the 20 items in the second condition. Participants were presented with the 20 response options in the first condition. This would be to assess if the different conditions affected the response options. The analysis of question 2 is I guess an extension/alteration of question 1.ДЇor this question I would like to compare the same participants groups across the same likert scale response options, across two different conditions. Or should I be maybe even looking at running an EFA to see if there are any items that hang nicely together and compare groups across these categories? So effectively I am looking at an IV of a dichotomous categorical variable and continuous/scale data DV.Д¬urrently I'm a little bit indecisive as to whether I should run a MANOVA,or individual t-tests, or individual t-tests with a bonferroni correction. I want to be able to see if there's a difference between the two participant groups in the mean scores for each of these items. There are two analysis questions I would be greatful for any assistance with. Although there is some distinction in the size of participant groups (60% to 40%) the data contains approximately 12000 participant so I should have reasonable power. I am presently reviewing data from an exploratory study where two groups of participants were asked to indicate on a 7 point likert scale the extent to which each of the 20 items presented to them 'influenced their decision-making'. Hi I am new to CrossValidate so wanted to thank anyone in advance for contributing and looking at my questions.
