In the context of constructing a frequency distribution, which statement best distinguishes class midpoints from class boundaries?

Class midpoints are the values halfway between the upper and lower class limits, while class boundaries are the values that separate classes without gaps

Class midpoints are the smallest values in each class, while class boundaries are the largest values in each class

Class midpoints are the actual data values, while class boundaries are the estimated values between classes

Class midpoints are used to define class intervals, while class boundaries are used to calculate frequencies
