Dr. W hypothesizes that hands- on classes will show more learning than lecture classes. Participants were randomly assigned to the experimental group (hands-on; N1 = 5) or the control group (lecture; N2 = 5). After learning, they took a 20-item test to see which group learned more. Experimental (hands-on)group:1 = 16.40 31 = 3.85 Control (lecture) group: 2 = 11.20 32 = 2.59 Answer questions below 1. HO: HA: 2. Directional or non-directional hypothesis? 3. One or two-tailed test? 4. What is the anlue (see page 433) given your degrees of freedom (N11) + (N21)? 5. If your Wfalls in the region of rejection, what does that say about the likelihood of getting that value by chance? 6. Calculate your Wand will you reject or fail to reject the null hypothesis? Why? 7. Is the probability of getting your W by chance alone greater than or less than .05? 8. What conclusion can you make regarding the research question? (Say if there i_s or is not a signicant difference between groups. If there is, say which group learned more.)
