When data collected using a qualitative variable, nominal variable (i.e., male or female), what is TRUE about a frequency distribution that summarizes this data?
Class midpoints can be computed.
Upper and lower limits of each class interval must be calculated.
Number of classes are determined by the number of values of this variable.
The "2 to the K rule" can be used to deternmine the number of classes.
