Consider the following statements related to cumulative frequency polygon of a frequency distribution, the frequencies being cumulated from the lower end of the range:
- 1The cumulative frequency polygon gives an equivalent representation of frequency distribution table.
- 2The cumulative frequency polygon is a closed polygon with one horizontal and one vertical side. The other sides have non-negative slope.
Which of the above statements is/are correct?
Elementary MathematicsStatistics
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
The ogive equivalently represents the distribution, and cumulating from the lower end yields a closed polygon whose rising sides have non-negative slope.
