Question

Now, Dr. Gatz needs your help to interpret the three z scores that you computed (z=0.77, z=-3.37, z= -0.3846). Based on Henry’s z scores of the memory test, the object naming test, and the Stroop test, do you think Dr. Gatz should focus his future investigations on Henry’s memory systems, naming systems, or attentional systems (i.e., those assessed by the Stroop test)? Be sure you could explain your reasoning?

Answer 1

The memory test score is 0.77 standard deviations above the average score which is good.

The object naming test score is -3.37 standard deviations below the average score which is bad.

The Stroop test score is -0.3846 standard deviations below the average score which is bad.

Therefore, Dr. Gatz should focus his future investigations on Henry’s naming systems, or attentional systems.

Please give me a thumbs-up if this helps you out. Thank you!
