Confused on H and I

Assignment 4 Name C OMO following are the cystatin C (mg/L) and creatinine levels (mmoll) of pediatric re- wransplant patients. Calculate the following for each variable. 1.78 2.24 1.86 3.78 Cystatin C (mgL) Creatinine ( mmolL) 2.16 4.69 0.35 1.82 0.12 0.17 0.30 0.11 4.93 0.07 1.75 0.20 0.14 Crastatin Creative EX1 -1.98 +2.10....+175 n 12. 0 .35 -- 10.19 a) Mean - Moco 2.078 an The middle most value after corranging = 2.16 - 0.4+0.17 c) Range - 4.93 - 1.75-3.19 d) Variance (X1-8) E 0.159 Rarse =0.35-007 0:21 20.20 V1.7.19 = 1 { 1.78 -2.778)² + (1 75 = 2778 EC ) 2 e) Standard deviation variance: 1, 2 3 (635-6.1829) -1.3122 (6.1% -6.1825) = 0.0024 ) Coefficient of variation - 1.3172 70.0094 2.7886 SD Vooby 70.5318 = 0.9722 g) Which set of measurements is more variable, cystatin C or creatinine? Justify your answer the stalnc (mob) have more vanance but CV is less than that of creatinine Hence both the data are of different values heuse Coefficient of vandtion since speriat of vandtion. Smle than, cystation then Creative dala you more more Verpaplity than chash,
