The original data values cannot be determined once they are grouped into a frequency distribution table.
举一反三
- True or False: The original data values cannot be determined once they are grouped into a frequency distribution table.
- A relative frequency distribution describes the proportion of data values that fall within each category.
- The percentage distribution cannot be constructed from the frequency distribution directly.
- When studying the simultaneous responses to two categorical questions, we should set up a( ). A: contingency table. B: frequency distribution table. C: cumulative percentage<br/>distribution table. D: histogram.
- The larger the number of observations in a numerical data set, the larger the number of class intervals needed for a grouped frequency distribution.
