the sum of frequencies for all classes will always equal - ANS-the number of elements in a data set
a frequency distribution is a tabular summary of data showing the - ANS-number of items in several
classes
the relative frequency of a class is computed by - ANS-dividing the frequency of the class by the sample
size
the sums of the relative frequencies for all classes will always equal - ANS-one

a histogram is said to be skewed to the left if it has a - ANS-longer tail to the left than to the right
a tabular method can be used to summarize the data on two variables simultaneous is called - ANS-
