| chhoda | 16, 17, 18... are the midpts, therefore 21.5-15.5=6 |
| bobert | What is the grouped frequency distribution that is mentioned in the explanation? |
| bobert | After reading the next question and its explanation it appears that a grouped freq distribution is simply one that has a range of numbers in its class. such as 12-19, 20-27, etc... |
| studyprep | here each bar has at least 1 frequency and class width is also 1, so we can find the range. But if class width becomes greater than 1, than we can not find the range. also see the next question. |
| Sm7272 | How do we know what element(s) actually existed there in the class 1 or the first bar. It could contain 10 elements of 16 , or 10 elements of 15.5. Definition of range is maximum value - minimum value. But how can we know what is the maximum data value from the graph ? Please clarify |
I was very pleased with your notes and question bank. I especially like the mock exams because it helped to pull everything together.
