- 1. Multiple Choice
This is the interval between two consecutive upper (or lower) class limits.
class width
class boundaries
midpoints
frequency
- 2. Multiple Choice
These are used as the border between two consecutive bars in a histogram. They are the intermediate value between an upper class limit and the next lower class limit.
class limits
class boundaries
frequencies
class marks
- 3. Multiple Choice
Why is this frequency distribution incorrect?
The fourth class width is different from the others
There is a zero.
Classes should overlapped.
