Pregabalin is the active ingredient of the medicine Lyrica; a drug used to treat epilepsy, neuropathic pain, fibromyalgia and generalized anxiety disorder (GAD).
Hmm, I'm a little confused on the difference between dichotomous and ordinal variables. I know dichotomous has two categories, but I'm not sure if that applies to all the options here. I'll have to review my notes.
I remember learning about this in class. A dichotomous variable is one that can only take on two values, like yes/no or male/female. So I'm pretty confident the answer is A, sex.
Okay, let me see. Dichotomous means two categories, right? So it's gotta be either A, B, or C since those all have two options. I'm leaning towards B or C, but I'm not totally sure.
Hmm, I'm not totally sure about this one. I know dichotomous variables have only two possible values, but I'm not 100% on the definition. I'll have to think it through carefully.
Hmm, I'm tempted to say D) Grade of Breast Cancer, but I think B) Pain yes/ Pain no is the safer choice. After all, you can't be 'kinda dead', can you?
