Examples of IVs and DVs?

[shinymeowstic]

Hello!!

I really struggle with picking out the IV and the DV and I face even more confusion due to them being used in Further (and being different).
So, can people please give me examples of a hypothesis or something, and then the IV and DV in the information?

And does anyone have any tips on how to figure them out? I just get so confused when they're in two subjects I do and I've always had difficulty with figuring them out. Then I doubt myself and change my answer a LOT and end up getting the right answer first then changing it to the wrong answer.

Hypothesis: That high school students who use narrative chaining will have better memorability of non-related words than high school students who don't use narrative chaining.

IV: whether or not high school students use narrative chaining to remember 10 non-related words

DV: the number of non-related words correctly free recalled out of 10

The DV is said to measure the effects of the IV. In my example the number of words correctly free recalled gave an indication of the effects of the IV
(e.g: use of narrative chaining = more words correctly free recalled)

The IV is the variable manipulated so you want to search for the thing that's being given to the e-condition but not the c-condition. It's usually a 'whether or not' proposition - as I've showed you in my example.

Another hypothesis: That primary school students who wear blue uniform will experience less stress in a maths test than students who wear red or green school uniform.

In this case there is no control condition so your IV will just be the variable that changes in the multiple conditions. So..
IV: whether the primary school student wears a blue, red or green uniform.

For you DV, think, what's being measured here? - the students stress levels. So..
DV: A perceived stress score out of 100

Sorry if I've made you even more confused hahaha
Hopefully another person can provide you with more clarification.

As we probably will have to identify the IV and DV in (at least) section C this year, why don't you go through chapter 1 of your textbook for some more practice? Or find some online.

Good luck with everything

Basically the DV is being measured in both conditions, and the IV is only present in one condition (experimental group).

The results of the dependent variable depend on the presence of the independent variable. The results of study scores (DV) depends on the presence of coffee (IV).
