The mean height of male adults in Ohio is 69.1 inches. We want to know whether this is different from the national average height for male adults (according to the CDC).
A) Identify the dependent (DV) variable
B) Identify the levels of the independent variable (IV)
- In these specific problems, these are two groups of people:
(A = sample vs. B = population or norm/data based on a population)
C) Indicate whether the researcher’s hypothesis is directional or non-directional
- Directional: A is (higher/lower) than B
- Non – directional: A is different from B
D) Write the null and research hypotheses (H0 and H1) in your own words
