Question
Please explain the process for solving this problem? u are doing research on depression and are using a depression-screening tool called t Depression Inventory (BDI). Higher scores indicate higher levels of depression. You the BDI to a group of participants and then converted the raw scores to z- so that you can more easily compare individuals in your sample to other samples. eck dministered cores colleague on your research team used your same data but chose to convert the raw cores into standardized T-scores instead of z-scores. T-scores are standardized scores in vhich a score of 50 represents (i.e., corresponds to) the mean and 10 indicates one standard deviation. Thus, a score of T = 60 is one standard deviation above the mean, while a score of 30 is two standard deviations below the mean. You each agree that your clinical cut-off score for identifying severely depressed people in your sample should be a one and a half standard deviations above the mean (anyone scoring that high or higher on the BDI would be considered "severely depressed"). Which of the followigg scores would be above the cut-off and result in identifying someone as "severely depressed"? Mark all that apply. T34 T = 55 T = 71 z 0.77Explanation / Answer
Answer:
Z score of above 1.5 is considered as severely depressed
Z score =( x=mean)/sd = (x=50)/10
When T=34, z =(34-50)/10 = -1.6
This is below 1.5, he is not severely depressed.
When T=55, z =(55-50)/10 = 0.5
This is below 1.5, he is not severely depressed.
When T=71, z =(71-50)/10 = 2.1
This is above 1.5, he is severely depressed.
Z=0.77 is below 1.5, he is not severely depressed.
Z= -2.43 is below 1.5, he is not severely depressed.
