- True or False: The larger the number of observations in a numerical data set, the larger the number of class intervals needed for a grouped frequency distribution.
- 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.
- The number of class intervals in a frequency distribution is usually between ___________.
- A cumulative frequency distribution lists the number of observations that are within or below each of the classes.
- In a data set, the number of observations will always be the same as<br/>the number of elements. ( <br/>)
