Q6. In a drug trial, 50 patients (samples) are divided into two groups (Group A and Group B) to identify the clinical effect of a drug. The data for patients in Group A are given in the following table: Group A Family history of Average systolic heart attack No Sex Patient Number Age blood pressure 122 1 32 Female 42 Female No 124 Yes No Yes Yes No Male Female 3 31 156 4 63 99 Male Male 138 109 48 30 57 Male 89 8 46 Male No 114 Male Female Male Male Female 9 28 No 86 10 54 No 134 11 38 Yes 146 12 53 No 134 13 51 No 115 Female Female Male Male 14 46 Yes 134 15 No 132 60 63 33 16 No 96 17 No 87 Male Female Female Male 18 45 No 93 19 29 Yes 152 20 34 No 121 21 44 Yes 112 22 | 23 Female Male No No 47 114 56 119 24 48 Male No 97 25 29 Female Yes 120 a) Differentiate between qualitative and quantitative data with examples. Identity the qualitative and quantitative data from the table. b) Calculate the variance and standard deviation of Age for the 25 patients in Group A. c) Calculate the standard error and co-efficient of variation of Age for the 25 patients in Group A. d) For Group B, the mean age is 46 with a standard deviation of 5.3. Using the answers fromb and c compare the variations of age in Group A and Group B.
