The following data give the index numbers of 100 commodities a certain year. Form a grouped frequency distribution, takin as class-interval. \begin{tabular}{rrrrrrrrrrr} 91 & 124 & 109 & 129 & 141 & 107 & 86 & 76 & 118 & 111 & \\ 99 & 99 & 114 & 100 & 88 & 108 & 87 & 101 & 101 & 71 & \\ 63 & 121 & 122 & 111 & 119 & 77 & 127 & 61 & 133 & 68 & \\ 77 & 117 & 110 & 95 & 96 & 96 & 86 & 106 & 119 & 79 \\ 81 & 127 & 86 & 153 & 79 & 129 & 151 & 89 & 143 & 147 \\ 90 & 142 & 105 & 94 & 125 & 96 & 99 & 138 & 145 & 113 \\ 129 & 87 & 113 & 110 & 144 & 91 & 106 & 104 & 97 & 115 \\ 100 & 117 & 73 & 134 & 108 & 102 & 123 & 106 & 119 & 104 \\ 101 & 120 & 112 & 138 & 140 & 103 & 96 & 136 & 78 & 83 \\ 75 & 100 & 113 & 114 & 109 & 116 & 109 & 116 & 104 & 128 \end{tabular}

Step 1
The range is the difference between the highest and the lowest values. In this case, the highest value is 153 and the lowest value is 61. So, the range is 153 - 61 = 92. Show more…

Tabulate the following marks in a grouped frequency distribution: 74 49 103 95 90 118 52 88 101 96 72 56 64 110 97 59 62 96 82 65 85 105 116 91 83 99 52 76 84 89 77 104 96 84 62 58 66 100 80 54 75 55 99 104 78 66 96 83 57 60 51 114 120 121 92 88 64 63 95 78.

A grouped frequency distribution table with classes of equal sizes 63 - 72 as one of the class is constructed for the following date: 30, 32, 45, 54, 74, 78, 108, 112, 66, 76, 78, 88, 40, 14, 20, 15, 35, 44, 66, 75, 84, 95, 96, 102, 110, 88, 74, 112, 14, 34, 44. The number of classes in the distribution will be a. 12 b. 11 c. 10 d. 9

Here is a data set: 35 53 91 56 90 117 51 59 54 73 62 99 27 87 26 79 67 67 23 46 65 75 73 23 67 49 35 73 Construct a grouped frequency distribution table (GFDT) for this data set. You want 10 classes with a "nice" class width. Your classes should be labeled using interval notation. Each class contains its lower class limit, and the lower class limits should all be multiples of the class width. In that the data appears to be discrete, use a closed-interval to label each class.
