I am trying to find a way to display individual results of a questionnaire after the survey to the participants. I have looked at stackexchange and googled quite a bit but it seems that I am not formulating my question correctly, as I have not found any helpful information.
Could anybody here point me to the right direction on how to figure this out?
Thank you so much,
Noemi
I tried to find information on how to even start doing this, but was not successful so far. I am probably not using the correct keywords to search. Any hints on that would already be amazing!

I have a three question quiz. I'd like the respondents to only be able to reach the End Of Survey only if all three questions are correct.
I am stuck at this point. There doesn't seem to be a way of "going back to the first question". Am I taking the wrong approach here?
If this has been asked before then I'm sorry.
I've been given this question and have been trying all weekend to figure it out. I've looked at multiple websites but none of them explain the process. It's really frustrating me. Can anyone help? So I've been given the first two pictures below. I'm just hoping someone could maybe explain this to me? I need to practice this for my exam!
New to posting here on stackoverflow, so please forgive any transgresses that occur.
So a little background....
My grandfather is a current computer science professor at a university. I have always taken a great interest in computers, and have really grown into dealing with the hardware side of things. However, him being how he is, he wants to me to have a broader understanding of computing in general. Including coding/programming.
SO to my question.... He has given me a Key P5FW-93F6. He told me, that if I am able to make other keys "with the same value" he will give me a reward. So as I am trying to solve this problem, I haven't a clue where to start. In the beginning, I have entered the code, and followed the pattern of Letter, Number, Letter, Letter, etc. into excel and used the random value function.. However, none of these keys work in his program. He told me there is a massive amount of different "Keys" that will work but will not provide hints on to how to solve the problem. What language should I learn to solve this? Should I be looking for a hash value to be the same as the one key listed above? I am completely lost... any help would be appreciated!
Thanks!!
P.S. I do have an unlimited number of attempts, however only have one line that I can enter at a time. So I can't make batch entries.
Ok this question is not exactly technical but very pertinent and current.
If you may have not heard Eureqa (http://creativemachines.cornell.edu/eureqa) is a machine learning (?) based tool that helps you find hidden equations and mathematical relationships within the data. It does sound futuristic and experimental and to a great degree it seems it is.
This is the relevant talk by Eureqa inventor Hod Lipson
http://www.youtube.com/watch?v=Xja6sLl6dVg entitled Mining experimental data.
So i believe this can become popular amongst many R users .
On the official site one can obtain Eureqa clients for MATLAB, Mathematica, Python etc but none so far for R.
So this question is just what it is , is anyone of you working on creating one...or if you know this project do you know what it will take to make one ?
I asked the same question on the Eureqa group a few months ago. Here's the link:
http://groups.google.com/group/eureqa-group/browse_thread/thread/cb251327b50dbd4f
The last entry has the following links:

I haven't tried this, so I don't know if it works. If you try it, please post your results.
I have the responsibility of ensuring that a colleague who is just learning R knows the basics before a course where that is a requirement. The colleague has gone through a couple of tutorials so hopefully she is ok, but I would like to give her a test to gauge it.
I was therefore wondering if anyone knew if there were any materials on the web that would be suitable? and is possible had both questions and answers.

There is a whole set of exercises with solutions from the book Data Analysis and Graphics Using R. (Maindonald & Braun, 2nd edn, CUP 2007) available online : http://maths.anu.edu.au/~johnm/r-book/2edn/exercises/
Next to that, a quick search using the obscure randomized pagecollector Google brought to me a set of exercises where you can pick out whatever you want. Try the magic phrase "R exercises". ;)
Some I found interesting :
http://www2.imperial.ac.uk/~das01/RCourse/Exercises.pdf (very nice)
http://dial.liacs.nl/Courses/MicroArrayDataAnalysis/Exercises/Introduction_to_R_Exercises_Nov_2004.pdf (rather basic)
http://www.shlrc.mq.edu.au/masters/students/raltwarg/altwargslp802.html (rather basic)
If this is just a one time single person evaluation then a oral style exam is probably going to tell you a lot more than a set of fixed problems. Get a data set and have her read it into R, do some basic data manipulation, a couple of plots, and a standard analysis or two. Based on what she does well or has a challenge with you can modify the direction that you have things go and what additional questions you ask.
