Use the given data for creation of a table with lowest limit as the lowest value and class interval of 5. Use that table for calculation of cumulative frequency, reverse cumulative frequency, relative frequency. Use Excel for these calculations. Then calculate the mean, median and mode of the data through that frequency table by manual calculation. 58 54 85 88 89 88 82 81 77 63 86 52 48 42 69 46 41 84 40 57 57 54 60 43 62 50 73 89 56 48 52 51 83 46 81 60 85 89 51 60 58 63 42 64 76 89 80 70 41 80 74 57 79 82 77 63 69 55 90 79 67 87 48 57 81 58 68 66 61 55 48 68 56 57 89 77 86 87 49 75 73 64 50 49 80 74 80 65 79 82 46 57 81 60 80 48
