Brooks/Cole Publishing Company.HSCI 190 Spring/Summer 2021 Problem #2 The Montgomery-Asberg Depression Scale (MADRS)2 is commonly used to measure the extent of depression amongst patients in psychiatric studies. Consider the following question from the MADRS: 2 . Reported Sadness Representing reports of depressed mood, regardless of whether it is reflected in appearance or not. Includes low spirits, despondency or feeling of being beyond help without hope. Rate according to intensity, duration and the extent to which the mood is reported to be influenced by events. 0 Occasional sadness in keeping with the circumstances. Sad or low but brightens up without difficulty. AWN - Pervasive feelings of sadness or gloominess. The mood is still influenced by external circumstances. Continuous or unvarying sadness, misery or despondency. A. Describe the level of measurement this question uses, and explain your rationale (i.e., why you believe that level of measurement is the correct choice). (1 mark) B. Imagine you collected the following data, calculate one measure of central tendency and one measure of variance to summarize this data. Provide your justification for your selected choices.

To conrm this suspicion, the investigators looked at the patients' bloodwork and reviewed the calcium and albumin levels (a type of protein) and compared the patients' values to the normal ranges of calcium (2.12 to 2.74 mmolfl) and albumin (32 to SSg/l) for healthy individuals. Their data is shown in the table. Patient Calcium (mo!!!) 1 2.92 3 .84 2.37 2.99 2.67 3 . l7 3 .71 3 .44 OO-quUl-P-UJN A. Identify the level of measurement of calcium and albumin in this data set and explain your reasoning. (1 mark) B. Identify the mean, median, mode, standard deviation, range, and interquartile range of the recorded calcium levels and albumin levels. (12 marks) C. Write a summary of your findings and whether or not you believe the patients fall within the normal calcium and albumin ranges based on your findings. (1 mark)
