Calculating SD's for a three- way ANOVA
S

Hi everyone,

I'm tackling an ongoing issue. I've ran a three way ANOVA on SPSS. It's computed the means and standard deviations for the three way interaction but not any of the main effects or two way interactions. How do I compute these? It's really important as I need to report these in my paper.

I've tried running separate two ways but of course, the means come and differently - and therefore the SD's are inaccurate. I would really appreciate some help on this.

Thank you for any advice.

Ways of Working
S

Okay so I'm a full time PhD student and I work best at home but I often feel this is often looked down upon from the other PhD students I speak to (who work in the office all week). One of them in particular keeps asking, ' Are you full or part time?' Ha!

Despite their hints, I had only just learned that two of the PhD students didn't start their experiments until year two. I started my PhD in October - I'm data collecting for two experiments and are in the process of planning my third. Clearly I'm doing something right...

But I'm a little stressed today - the task I had planned I'm just not in the frame of mind to do. In fact, I'm just not in the frame of mind to do anything. Which makes me feel guilty. But when I'm like this it's best to just leave it until another day - anything I come out with when I'm like this is just crap. The inspiration isn't there. But it makes me more stressed.

Has anyone else felt like this?

How many experiments should you aim to complete?
S

Hi,

I'm a new PhD student and got a bit of an alarming wake up call at my last supervisory meeting. I'd planned to do 3 clear cut experiments in my first year, and four for the second. I wanted to treat each experiment like an individual dissertation... thorough 8,000 word write ups... extensive literature searches for each and a real knowledge of what I wanted to investigate and find out until....

My supervisor suggested I submit around 3-5 experiments for ethical approval next month...! How on earth can I set five experiments up thoroughly so that they are well designed, well thought etc etc in that time? How can I complete extensive lit reviews and have a real sense of what I am setting up?

Then my second supervisor added that he had completed 20 experiments throughout his PhD.. but only 9 were included in the thesis. To me, this seemed like a pretty big waste of time - 11 sets of data collection not used.

I think they think I should run as many experiments as possible and abandon the ones that don't work. I do not know whether I can do this. At least, not to the standard I would want my work to be at. And if you as submitting multiple experiments to ethics at once- how can you feed the results of one experiment into the other...?

I guess it comes down to quantity or quality. I was just hoping for some advice really. I'm a psychology student and are aware that different subjects require different numbers of experiments. I'm having difficulty knowing how to move forward..

Any advice appreciated :) As you can tell I'm new to this!
