Here is a data set: 262 143 161 311 307 150 234 204 174 210 128 273 228 183 184 260 128 243 209 311 190 169 197 179 190 155 188 311 Construct a grouped frequency distribution table (GFDT) for this data set. You want 10 classes with a "nice" class width. Each class contains its lower class limit, and the lower class limits should all be multiples of the class width. Note: the data ranges will be hand graded after the due date for this assignment. If your frequencies are marked correct, you most likely have the classes correct.
