As the Likert scale data is, basically, not an interval or a ratio scale data, the statistical assumptions are violated when a social science researcher uses the mean and standard deviation to describe characteristics of the data. Avoiding the misuse of mean and standard deviation in social ...
The Likert Scale Chart is a universal tool for surveys. Respondents provide their opinions (the data) using multiple scales. The survey data can then be measured with nominal, ordinal, interval or ratio levels. With so many options and levels, the Likert Scale Chart is the gold standard for...
Types of data measurement scales:nominal, ordinal, interval, and ratio. What is an example of interval? An interval scale is one where there is order and the difference between two values is meaningful. Examples of interval variables include:temperature (Farenheit), temperature (Celcius), pH, SA...
According to Stevens the most common division of measurement scales distinguish four main types: nominal, ordinal, interval and ratio. The chosen scale of measurement implies further the possibility of applying certain statistical methods. For socio-economic research it is frequent that among independent...
Likert scales and similar measurement tools produce ordinal variables, but statistical methods typically used to evaluate attitudes treat variables as interval or ratio.; The objective of this research was to determine the relative accuracy of three different methods for testing the hypothesis that ...
The data obtained from the Likert Scale are typically treated as the interval. Thus, we can say that Likert scale possessesdescription, order and distancecharacteristics.Descriptionmeans the unique labels or tags designated to each value of the scale;Ordermeans the relative position of the descriptor...
A very common question is whether it is legitimate to use Likert scale data in parametric statistical procedures that require interval data, such as Linear Regression, ANOVA, and Factor Analysis.

t = 28.199, P < 0.001, 95 % confidence interval (32.46-37.34). The NDI score was correlated with Likert scale rating of patients (Figure 2). There was a positive correlation between NDI and Likert both before (r = 0.589, P < 0.01) and after (r = 0.776, P < 0.01) ...
This study suggests transformation of ordinal data into binary data, interval or ratio before going into parametric analysis. Secondly, increase the number of points on the Likert scale, preferably to seven (7) to enhance reliability, validity, discriminating power and respondent preferences. Thirdly,...
