g. Remember back to the last lecture, in which we talk about z-scores. What raw score would correspond to a z-score of 0 in this dataset? What raw score would correspond to a z-score of 1.00? Hint: consider the units of z, and what a positive value of z means. For z=0X= For z=1.00X= 2. Calculate the mean, median, mode, SS, (sample) variance, and (sample) SD for the following dataset. Please show your work (at least the general calculations that you made to get to your answer, where applicable). 42,54,43,47,58,49,63,55,56,47,55,61,59,48,55,53,41,60,50,55 a. Mean 52.55 b. Median 54 c. Mode 55 d. SS 782.95 e. Sample variance 41.2 f. Sample SD 6.4 g. Remember back to the last lecture, in which we talk about z-scores.
