Please read below. I need help right away. I have posed this problem in three different ways an the only consistant answer I get is instructing me to go pay money to another site. PLEASE HELP!
Inferential Research and Statistics - I need help writing a paper with a hypothesis regarding Clinician's at a clinic who are using a new method to treat veterans for PTSD. Please see below for the data sets to work with. I must decide what the numbers represent. The sample size is 30 for each group. Please see example and groups below.
You have a hypothesis that two drugs have different effects on lowering anxiety. You would have anxiety scores for drug A and anxiety scores for drug B (all after 4 weeks of treatment) to run inferential analysis for after 4 weeks.
- Null hypothesis is H0: drug A = drug B
- Research hypothesis is H1:drug A ≠ drug B
- Dependent variable: Anxiety score changed after treatment.
- Independent variable: drug treatment
Because you did not state a direction in your hypotheses (better than or worse than), this will be a two-tailed test. You are looking for differences in either direction. You would set your alpha level of .05 and have a sample for each group of 30 people that were volunteers for the study.
