What is the purpose of an ungrouped frequency distribution?
What is the purpose of an ungrouped frequency distribution?
- To display cumulative frequencies for each class
- To group data values into classes and count the frequency in each class
- To calculate relative frequencies for each class
- To summarize data values with corresponding frequency counts (correct)
In an ungrouped frequency distribution, what does the relative frequency for a class represent?
In an ungrouped frequency distribution, what does the relative frequency for a class represent?
- The percentage of the class frequency relative to the total frequency
- The difference between the class frequency and the total frequency
- The sum of the frequencies for all the classes
- The frequency of the class divided by the total number of observations (correct)
