- [Instructor] This worksheet shows the results of two experiments using a binary outcome variable which is improvement versus no improvement. The relevant figures are in the range B5 through G6. For example, in the first study in row five, there were 202 participants, according to cell D5. Of those 202, 31 improved and 171 did not. In the same study, the comparison, or control group, had 203 participants, as shown in cell G5, of which 61 improved and 142 showed no improvement. Column H shows the odds of improvement in the treatment group. The odds of 0.1813 in cell H5 is calculated by dividing the 31 who improved by the 171 who did not. Similarly, the odds on improvement in the treatment group for study B in row 6 is 0.2813, calculated by dividing cell B6 by cell C6. The odds on improvement and no improvement for the comparison group appear in cells I5 and I6 and are calculated in much the same way as for the treatment groups. The odds ratios in column J are calculated by dividing…
