Dr. Whitlock is conducting an experimental study on the effectiveness of antipsychotic medication Which of the following will most likely be her dependent variable?

A) Type of medication, because this is the variable she is manipulating.

B. Frequency of auditory hallucinations, because this is the variable she is measuring.

C. Self- reported depression, because this is the variable she is manipulating.

D Serotonin levels, because this is the variable she is measuring .

E Age of first symptoms , because this is the variable she is measuring

D Serotonin levels, because this is the variable she is measuring .

Explanation:

Dr. Whitlock is looking for the effectiveness of the medication.

A. is incorrect because it say the type of medicationn was being manipulated if this were true this would be the independent variable (the thing the scientist or person changes)

So just by knowing why A is wrong we can automatically rule out

A.

C. and

E.

That leaves B. and D. giving you 50/50 chance of being correct if this were on an actual test/EOC.

I am a little unsure of if it would be B or D at first so I decided to leave some information for you in case you disagree or want to check I'll leave it up to you to officially decide if it's B or D but I personally believe it's D. here's the information:

You can Eliminate B. because Dr. Whitlock is looking for the effectiveness of the medication and D. is talking about the serotonin levels, serotonin affects your mood, low serotonin levels can cause depression. But if serotonin effects your mood is that something a anti-psychotic medicine be prone to fixing or would it be the hallucinations? which many experience but do the serotonin levels effect your sanity more than the auditory hallucinations, cause people can have inaudible hallucinations.

I may be looking into to this WAY too much and OVER thinking it but I hope this at least helped you a bit giving you a 50/50 chance of getting this right. Sorry if this is confusing.
