$\begingroup$ I agree with Mr. Jeromy Anglim's justification on the use of mean (i.e., weighted mean to be exact) as the most reliable unbiased more descriptive interpretation of ordered categorical variables such as the use of Likert scale where each of the data points contribute to the final average. It is meaningful for interval and ratio scales Mean(1, 1, 2, 4) = 2.0 Median (x) The same number of samples are higher and lower than the median (middle value) Well defined when n is odd (ordinal scale) Median(1, 1, 2, 4) = 1.5 valid only for interval and ratio scales ~ Unfortunately, this is not really acceptable from a statistical format. This will get you started with SPSS syntax. Thank you very much, Unlike nominal data, ordinal data examples are useful in giving order to numerical data. On the right side of the submenu, you will see three options you could add; statistics, chart, and format. A good solution when analyzing Likert data is to design a survey containing a number of Likert questions that all point in the same direction. Often times, researchers go right into Inferential Statistics and Skip the Descriptive Statistics, since it is less informative. The Likert scale that you may find in many surveys is one example. Once you have the mean values for both, perform the t-test. 3. Descriptive statistics used for Likert-type data includes mode or median for measuring central tendency and frequencies for variability. on a continuum from strongly agree to strongly disagree, and makes the assumption that attitudes can be measured. . likert scale 1. Likert scales were developed in 1932 as the familiar five-point bipolar response that most people are familiar with today.3 These scales range from a group of categories—least to most—asking people. The Likert responses are typically considered as ordered categorical (i.e., ordinal) data, because they convey size, order, rank or sequence. You can use descriptive statistics to summarize the data you collected in simple numerical or visual form. The rigorous analysis is to get a Weighted mean, which Analyse-it does not do. For example, if you have a variable with a Likert scale ranging from 1 - 5, all of your values should be in this range. For example, each of the five (or seven) responses would have a numerical value which would be used to measure the attitude under investigation. In an ordinal scale, responses can be rated or ranked, but the distance between responses is not measurable. In our example here, it only tells us that the people with higher-numbered responses are more in agreement with the party's positions than those with the lower-numbered responses. (The primary focus of this course is on questionnaire/survey data and Likert scales; for a more detailed look at data analysis in SPSS, our courses descriptive and inferential statistics in SPSS courses are recommended) This course is .
