Re: Hypothesis or research questions or both?

Kate

 

If you send me your research proposal, questionnaire(s) and your latest SPSS saved file (off-list and in complete confidence) I’ll have a look at them and get back to you.  Note however that I’m hotter on logic and operationalisation than I am on statistics.

 

I’ve copied this to the list so everyone else can see where you’re at.

Dear John,
Through your inputs and guidance to other novice researchers like myself, I have always been impressed by the quality of your support to novice researchers. Many thanks for this. I am always referring to your website for SPSS questions, and it has been an emporium source of support to me.

As a PhD student specializing in social science research methods, I am investigating methods effects in quasi-experimental mixed methods research using survey questionnaire and interviews and bio-narrative essays. Data will be collected in two different phases and I will compare results between Phase 1 and Phase 2 as resulting from different data collection tools. But I need your guidance whether my study design requires hypotheses or research questions or both. Do all quasi-experiments necessarily need hypotheses? Any reliable open-source latest publications would help.
All the best in 2013,
Jean Providence

Brian has already answered on the Fleiss issue, but since you’re a novice user you might like to check out the syntax-based SPSS tutorials on my website.  I know it’s only for an undergraduate project, but SPSS will stand you in good stead in the job market in future.  The course is based on the latest version (1991-92) of one taught to my undergrad BSc Social Research students, four of whom now hold full Chairs in UK universities.  There’s nothing yet on hypothesis testing or modelling, but there’s plenty on data capture, data management and first steps in analysis.

Kate,

 

I have a macro for Fleiss.  Perhaps that's the one to which you're referring.  I can send it to you offline because the listserv does not accept attachments.  I'm going to upload it, along with several others, to SPSS Developer Central in the next few days so it will be available to everyone.  I think your problem is not adjusting the syntax as much as understanding how interrater agreement statistics work, not just Fleiss but others as well.  Using your example and the macro you have (I think), the raters are columns, the patients rows, and the categories to which the raters assign the patients are in the cells.  The macro uses a matrix approach, so string variables (e.g., A, B, etc.) will not work.  You'll need to use 1 for A, 2 for B, and so on, and then translate back to the strings. Cases/subjects having missing data will be eliminated from the analyses.  All the most used statistics (e.g., Cohen, Fleiss, Krippendorf) do not deal with missing data.

 

I should be in my office tomorrow and can forward that to you.

 

Brian

Hi David,

Thank you for getting back to me... I looked through most of the old threads before signing up but I couldn't find anything that A) I could understand and/or B) that answered my question so sorry if it has already been discussed else where.

I have found the standard MACRO release supplied by IBM/SPSS for multi-rater agreement analyses, however, I don't know how to alter the coding to fit my parameters;

As an example, in one data set I have 15 raters all rating 12 patients according to 4 categories (treatment A, treatment B etc). I'm unsure how to instruct SPSS to compute this for me.

Any help at all appreciated as I feel as though I'm attempting to read an alien language.

Warm wishes

Kate

"I have the syntax master command but I have no idea how to alter the coding to fit my requirements"
What does this mean?  Please be very specific.
This topic has been discussed recently please review that thread from a few weeks ago.

Hi,

I'm a final year undergraduate student who is a little lost trying to add and alter syntax in SPSS and I'm hoping someone will please be kind enough to help me? Sorry in advance for any poor statistical language usage... it's all a little new to me so here goes;

I'm attempting to work out the level of agreement between multiple raters up to 15 regarding up to 13 different patients. I believe that due to the level of my data Fleiss Kappa is the best option for me. I have the syntax master command but I have no idea how to alter the coding to fit my requirements... Does anyone have a walk through or could provide me with any help at all as I'm terribly confused!

Thank you all in advance

Kate
