Null Hypothesis Significance Testing
Please analyze the data according to the NHST steps. Show your work and respond to as much of the following as you can.
STUDY 1
STEP 1 Design a study (Make a choice for the items that have a choice/choice below)
a) observation/correlation/experiment?
b) Model variable is IV/predictor/QIV/none?
c) Outcome variable is nominal/ordinal/interval/ratio?
d) Model variable is continuous/discrete?
e) What parametric assumptions still need checking?
Assume representativeness = yes and linearity = yes.
f) RQ: What is the effect/association of _____________ on/to ___________?
STEP 2 State mutually exclusive hypotheses
a) H0:
b) H1:
STEP 3 Calculate test statistic(s), df, and effect size(s). Indicate whether the effect size(s) are small, medium, large.
STEP 4 Compare to alpha level
STEP 5 Invoke a decision rule and draw a conclusion(s)
STEP 6 Interpret and report Write up the results in APA style, include appropriate descriptive statistics, inferential statistics, and effect size. Interpret the results in terms of the research question(s).
