Hmm, I suppose it's not peer reviewed, in which case you could just call it "Non-peer reviewed literature". However, if you're in an area where peer reviewing isn't that common, this wouldn't work. Could you just refer to it by title? Again, I suppose this depends where you found it...

Hi all,

This is probably a question more for the medical/biological scientists out there, but anyone's opinions would be most welcome. I currently use Ovid MedLine for literature searches, but have used Web of Science in the past. Seeing as now would be a good time to change if necessary, can anyone give me pros/cons of either of these, and also which they prefer?

Thanks :-)

Matt

Thanks for that teek :) I should have also added that I'm in incorrigible obsessive and perfectionist. A trip to London tomorrow should take my mind off it though...

I've just finished a research project which I've handed in, and now, after I've handed it in, I've thought of an error (always the way). Even though I proof-read the manuscript several times, I've printed one of the graphs in black and white. The graph is a histogram, with bars grouped into categories, and each bar is coloured depending on how the parameter was measured. I have three colours on it - green, red, and blue. You can just about tell which is which, despite it being in black and white, but having spent the last 12 weeks working extremely hard on it, I'm worried that I'm now going to get a lot of marks taken off just because this graph isn't in colour.

I could tell my supervisor that it's something that's just come into my mind, and ask her to bear in mind that the bars AR actually coloured differently, and there's an electronic copy I submitted with it, which of course contains the colour graph. But if I tell my supervisor, I might be drawing her mind to it, so I really don't know what to do.

I was hoping to have a first stress- and work-free weekend in over two months, but this is going to be playing on my mind all the time now :-(

Any suggestions?

Sim, I love you :-x

Hi everyone. I've copies some tables from Excel into Word, but when I print them in Word, the gridlines don't come out. I can't find any option in Word to "print gridlines" like there is in Excel. Can anyone please please help?

Thanks very much in advance :-)

Hi Lostinoz!

I'm in biomedical sciences. Generally, the first author is the person who has done most of the lab work, the last author is the PI/grantholder, and they'll write the manuscript together. Second author is pretty good too, and then it goes downhill from there.

Dan B - now that's the kind of answer I like! To be fair, my supervisors have pretty much said that they're not important. In fact, most academics in my area seem to loathe stats, and see them as a means to an end, rather than actively enjoying putting them in there.

Good question about why n=2. I'm doing the masters year of a 4 year PhD, and my lab project only lasts 10 weeks. My sup thinks I've done well to get better than n=1 - there's no way it's going to be published anyway, so it's just about doing what I can in the time available.

I only have n=2 for each group though, so I don't think I can really do these checks...

I'm going to stick with Bonferroni because it's not going in my viva, and it's what my supervisor's used in the past! Thanks very much for your help with that :)

Matt

Nowwww I see it.  So really I don't have to do a t-test because it's done it all for me, AND the Bonferroni correction means that the p-values are as they should be, and don't need dividing by 2 any more...

Thanks for that Sneaks.  So I've done my ANOVA, got my p value, which is nice. I selected post-hoc bonferroni, but it just gives me some differences, which seem to be between one group and the other two for all cominbations, and tells me that the differences are significant at the 0.05 level.  It doesn't actually give me a p value for between two groups.

2 things - am I right in thinking ANOVA is basically like a T-test which covers all combinations, so for A, B, C, it will test A v B, B v C, and A v C? 

So basically, I run an ANOVA, and look to see if P<0.05 for any combinations of groups. Then if it is, run t-test between those two groups?  I'm not sure I understand the bonferroni correction though...

I have some cells, which I've divided into three sets, and given each set a different treatment - one is control, and let's call the others chocolate and beer (mmmmmmmmmm). I have measured each set's reaction to this, and I want to see whether either of the treatments cause the cells to react in a significantly different way to the control set.

Am I right in thinking that I need a student's t-test for control vs chocolate, and then control vs beer? And could I then do the same test for chocolate vs beer? Or is there some test which takes all three into account at once?

I'm obviously a bit of a stats newbie, and people here seem to have stats, so if anyone can help, it would be most appreciated :)

Matt
