If a Likert Scale question has answers with a mean of 3.95 and the standard deviation is 1.214, then is it acceptable for marketing research? If you make this assumption, and I don’t think you should make it, then you can use the formula described in the post, which produces a mean value of 3.94. can I ask where to find the explanation about this scales? Our global writing staff includes experienced ENL & ESL academic writers in a variety of disciplines. Peter´s mean for the variable attitude: 2.75. As I wrote at the beginning of this post, one of the papers in the volume that I reviewed made the statistical mistake that I just described, namely it described a set of findings that had been generated by extracting mean values from Likert items. A possible counter-argument is that doing so will lose some of the granularity of the scale. I hope you are able to help me. However, you might find some help in this post. Hi! In fact, I have found a journal article that used multiple regression on using Likert scale data.

KRl-20 and KR-21 only work when data are entered as 0 and 1. hi, i want to find out the significant relationship between English language teachers methodology and students’ performance, what statistical tests I should use for it. in case my likert has both positive and negative statment .. how should I calculate total score?

Their argument is if you have big sample size, Likert type data can be considered for statistical operations e.g. If you treat them as ordinal data, then you can also calculate the median, which is a slightly more refined measure of central tendency. Thank you. Is there a connection between mean and the bar graph percentage and can I link the two? Either way, I would not recommend calculating a mean. Flood If a Likert Scale question has answers with a mean of 3.95 and the standard deviation is 1.214, then is it acceptable for marketing research? However, if only the first and the last response options are labelled and the respondent is asked for the strength of their reported opinions/ feelings (e.g., on a scale of 1-6, where 1=very bad and 6=very good), then the intervals can be assumed to be equal. 4) do u mean that once i use spearman rho, I do not need to use linear regression on my data any more?
