Hi

I'm not really sure what the question is asking really, I haven't started Biology yet!

But is it meaning what you can use to show the data? i.e. graphs?

May be you could wait until some one else pops along.

Sorry I'm not much more help!

Here is a good read giving you a foundation knowledge of the different concepts in Statistics.

If you have any more specific questions about this project, fire away :twisted:

Hey, i was wondering if anyone could help. I have just started my planning a research project for biology. I thought I had done really well in my psychology unit of this but was gutted when i only got a pass :( so this time i really want to make sure i am understanding. I am a bit stuck at creating a title. Are we sticking to the aim.. an investigation to measure effect of personality on the stress response? Or do i have to change it slightly when i am writing out the plan?
I no what task i am going to carry out and going to use pulse rates to measure. However do i have to just select say 20 people? or do i have to determine if they are type a or b personalities first? And then compare pulse rates during the task to see how different the stress response is. I am a bit confused as to what the actual aim of this task is and as it is holidas i cant get in touch with my tutor.
Thanks
Rachel

Hi Rachel

Use your hypothesis and null hypothesis for your title, and yes, you select 20 subjects that you are going to use.

Good luck :thumbup:

Thankyou, am i right to think im selecting 20 participants and then getting them to carry out my task. I will measure there pulse whilst during the task and then compare pulse rates to see what type personality they will be? Or ... im just not quite sure as to what i am meant to be finding out.
Thanks Rachel

Can I ask how you went about selecting a sample please? I'm not working at the moment and realistically my only opportunity to get a sample together is through family. However there's no way I'll be able to find 10 type As and 10 type Bs. I do know one classic Type A who had a heart attack last year, but he's so hostile as to be an absolute no-go!

Thanks. And did you find all the Type As you needed from there? I really don't have much to do with driven, frenetic types so I think this is going to prove a problem.

I think you'll find you probably know more Type A's than you think.
I was surprised at how many people I thought would be Type B scored as a Type A.
You don't need to have a matching set - but I think it's easier, as if they don't match you have to do some other calculations before you can do the inferential statistics test.
