A sample of n = 20 scores ranges from a high of X = 7 to a low of X = 3. If these scores are placed in a frequency distribution table, how many scores will be listed in the first column? Solution there are 5 levels 3 4 5 6 7 so if they are uniformly distributed there would be 20/5 numbers in the first column. so there would be 4 scores. Without knowing more about the distribution it would be hard to answer differently.
