In a histogram when dealing with sets of scores... what if the scores start at 54. If 54 is the lowest score it wouldnt make sense to start the first set with 0-10, would we start at 50(50-60) or 54 (54-64)? I would assume to start at 54 but i kno im wrong what is the rule where should my sets start at at what number ?

Solution

To draw a histogram, one must decide how many intervals represent the data, the width of the intervals, and the starting point for the first interval.One must choose a starting point for the first interval, which must be less than the smallest data value. A convenient starting point is a lower value carried out to one more decimal place than the value with the most decimal places.

For example, if the value with the most decimal places is 6.1, and this is the smallest value, a convenient starting point is 6.05 (6.1 - 0.05 = 6.05). We say that 6.05 has more precision

would we start at 50(50-60)
