举一反三
- When constructing a frequency distribution, classes should be selected so that they are of equal width.
- Which of the following best describes a frequency distribution A frequency distribution is a grouping of:（） A: data into intervals (classes) so that the number of observations in each of the non - overlapping intervals (classes) can be seen and tallied. B: selected data into intervals (classes) so that the number of observations in each of the non - overlapping intervals (classes) can be seen and tallied. C: dependent intervals (classes) so that they can be seen and tallied.
- True or False: Determining the class boundaries of a frequency distribution is highly subjective.
- True or False: The original data values cannot be determined once they are grouped into a frequency distribution table.
- True or False: In general, grouped frequency distributions should have between 5 and 15 class intervals.
