Likert等级量表是一种定距量表,量表所收集的数据可以借助统计软件(如SPSS)进行各种参数和非参数检验,以此来挖掘量表所反映的深层信息。在实际设计中,Likert量表通常采用3~7个等级形式,即量表中各题项给出表示态度积极程度等级的几种备选陈述(如“非常符合”……“非常不符合”等),并用不同的分值给每一等级陈述...

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.
Step 5 – Make a Report on the Likert Scale Analysis Select the rangeB4:H4and copy it to the clipboard. Go to a new spreadsheet and right-click on the cell you want to start the report (we have selected cellB4here), then click onPaste Specialfrom the context menu. ...
本文首先从发展背景、基本理论、检验方法以及与其他量表的比较等方面对Likert量表进行了探讨,然后结合作者实际参与的苏州市民文明指数的调查,利用统计软件SPSS对文明数据进行系统化的实践操作,最后给出了分析结果和建议。在分析的过程中,我们发现将Likert量表的数据作为离散型数据来进行分析,并采用非参数检验进行分析,更具有...
1. There is a difference between a likert scale item (a single 1-7 scale, eg.) and a full likert scale , which is composed of multiple items. If it is a full likert scale, with a combination of multiple items, go ahead and treat it as numerical. ...
Using R or SPSS does anyone know a nice way to visualize this data. I need something like this: (fromJason Bryer) But I cannot get the initial section of code to work. Alternatively, I found really good examples of how to visualize Likert data from a previous Cross Validated post:Visuali...
