The Ongoing PSYA4 Discussion Thread- June Exam :)

When looking at type 1 and 2 errors what is it that we need to know?

When looking at type 1 and 2 errors what is it that we need to know?

Clinical characteristics = Symptoms

Group 1 :

-Thought control
-Hallucinatory voices
-Other persistent delusions (EG, Delusions of granduer)
-Delusions on control/influence/passivity

Group 2:

-Catatonic behaviour
-Irellevant/Incoherent speech
-Other persistent hallucinations (Visual/auditory hallucinations)
-Negative symptoms

Type 1 rejects the null hypothesis when its true which creates a false positive result - saying there is a significant result when there is not
If a more lenient significance level (0.01) would increase the Type 1 error chance

The probability of making a Type 1 error is the level of significance used - 0.05 there is a 5% probability of making a type 1 error
If you use 0.01 there is 1% of making the type 1 error

Type 2 accepts the null hypothesis when it is not true
Creates a false negative (i think of pregnancy tests saying negative when really theres two people in one - my teacher suggested it it works for me lol)
the chance of a type 2 increased if the signficance level is too strict of too small a sample
The probability of making a type 2 is generally unknown

hope it helps someone :|

Because my PSYA3 resit seemed to go pretty well, I need around 70 UMS in this paper, so around 45 raw marks... Looking at it this way, I seem to be fine, but I am still panicking (I think they will increase the grade boundaries) :/

What do people think will come up for research methods?

Also, how do you design a debriefing form?

This is nowhere in my books. And say they ask you to design one, do you just simply write what you are going to put in it (e.g. the debriefing form would contain _____ and ____), or like actually draw one or something and write it out like it was a real one.

if someone still wants my media. here.

it's very colourful and easy to read.

If you're asked to write a debrief form you write it as you would want participants to see it, no introductory stuff, just straight and to the point. In a debrief form you would need to put:

* Any deception you used and why you used it
* A breif description of what the study is and what the results will be used for
* Under ALL circumstances put you may withdraw your data from the study and add some fake contact details for the researcher. This = easy marks reallu/

Thanks Charlotte, you know your stuff!
What other topics are you doing?

And good luck for tomorrow!
