which of the following are characteristics of frequency tables? more than one answer may be correct.
☐ the percentage of observations in each class is provided.
☐ no observation can fit into more than one class.
☐ they can be used for quantitative data.
☐ they can be used for qualitative data.

Explanation:

1. Frequency tables can include relative frequencies (percentages) for each class, so the first statement is valid.
2. Classes in a frequency table are mutually exclusive, meaning no observation belongs to more than one class, so the second statement is valid.
3. Frequency tables organize counts of data; they work for quantitative data (e.g., age groups) so the third statement is valid.
4. They also work for qualitative data (e.g., counts of different categories like colors) so the fourth statement is valid.

Answer:

• The percentage of observations in each class is provided.
• No observation can fit into more than one class.
• They can be used for quantitative data.
• They can be used for qualitative data.
