I am rather not sure if I shall add it to my results. In my case r is about 0. Thanks a lot Marta. I am currently trying to assess the relationship between pain intensity and pain-pressure threshold. Participants are asked to fill in different pain scales prior to having their pain pressure threshold assessed, this is then repeated on the next session.
This leaves me with 2 sets of pain intensity ratings and 2 sets of pain pressure threshold per scale. Would you happen to have any other suggestions of data analysis? I would like to ask a few questions to try aand understand things better. What happens between the first pain pressure assessment and the second? Why are you expecting any change? What did you find was the correlation between pain intensity and pain threshold on the first trial? What was the correlation on the second trial? The website describes how to perform two sample correlation testing, using an approach which I believe is different from the one you described.
The independent sample case is described at. Your experiment seems to be using dependent samples. This is described on the webpage. The formulas for the referenced test are all on the referenced webpage. Hi Charles, the excel add-in tool available on your website is incredible. I recently came to know about it from a fellow classmate. My question is as follows: — I was trying to find the correlation between the returns on Private Equity investment by a bank and some of the PE indices available on Bloomberg.
If not, are there any better alternatives I can explore? It is a measure of agreement between different raters. Thanks for the website and the super-helpful information. For instance: 75 samples, each rated twice. Dinh, Whatever tool you use to send emails will have the ability to add attachments to your email. An Excel spreadsheet is just a file. All you need to do is attach this file to your email. Previously I asked a question related to the negative W result. I have found that before doing the calculation, each set of tied ranks should be corrected based on the Mann-Whitney U test.
When I applied this, I got the positive result. I also checked with the manual method described by Sheskin, D. I got the same results but the W value was negative. Could you please explain to me why it was the case? One problem that I have experienced is the sum of rankings on each row is different from yours for each row. Mine is by summing the values of each row up.
Hi Dinh, In this test if there are k subjects to be rated then each rater must rate one subject 1, another 2, another 3, etc. SPSS however demands 2 variables. Thank you so much! Thanks for the info. Hello, Charles, My question is to some extent related with the previous questions regarding Likert scale. I have at least 20 indicators, divided in different groups, and the experts are assigned to evaluate each indicator from 1 to 5 comparing the particular indicator with other indicators within the same group.
In order to calculate W, I will rank the experts evaluations. However, as I can see now from the results, there is a dominance of 5 and 4 points in experts answers. Since many of the indicators are very important, they are evaluated at the same highest points. Will it be a problem in order to get a high and significant value of W? The rating used in ICC captures the scale of the rating. If yes, can U please give me the reference at the earliest? You can get some idea of weak, strong, very strong, etc.
Also the lower the p-value the more significantly different W is from zero. There are subjects that made the Top list in all 3 rankings. I should mention that there are several ties in each of the rankings. The median difference is Standard Deviation of the difference is The maximum difference is Such large summary statistics suggest that there is not a high level of agreement. This seems far too large. You have made an interesting observation. Please shed some light on how to go about it.. Follow the approach shown in Example 1 of the referenced page.
The only difference between your problem and Example 1 is that you require rows instead of 7. Charles, Thanks for your quick response to this matter. My problem however is that each respondent in the survey is not asked to rate the 8 statements from 1 to 8. I feel the example given are different. Very interesting topic, i do some beer tastings with friends and want to analyze the data, so i am reading about this, could you throw some light on which methods are good for ordinal data?
Do you think Pearson or Spearman are adecuate to compare one judge with another? We are giving free scores from 0 to 10 not ranks , and we are not assigning fixed points like your W Kendall example and the rest i read on the internet i think , thus, one person can give 10 points to each beer and another 2 points…i attach the results here so you can understand better what i am saying. Pep, From looking at the data that you included it seems that you might want to use the intraclass correlation coefficient. In my research, i have used Delphi method 3 rounds using the Likert scale.
Now, I have 60 judge-experts and 11 indicators. AVG function and then follow the approach in Example of the referenced page. When you say you have 11 indicators , does this mean the Likert scale is 0 to 10 or do you mean that there are 11 subjects being ranked? If i reject null hypothesis, i conclude that there is agreement among raters. RSS - Posts. RSS - Comments. Real Statistics Using Excel. Skip to content. It turns out, however, that there is a linear transformation of W that is a correlation coefficient, namely In fact it can be shown that r is the average Spearman correlation coefficient computed on the ranks of all pairs of raters.
Now define W as follows. Example 2 : Repeat Example 1 taking ties into account. The calculations are shown in Figure 3. Junel says:. October 9, at am. Charles says:. October 9, at pm. Romeo says:.
