Does cumulative frequency is the total of all class frequencies up to but not including the frequency of the present class?
No.
How is a frequency distribution converted to a relative frequency distribution?
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
Definition of ogive diagram?
An ogive is a type of graph that is used to represent the cumulative frequencies for the classes in a frequency distribution. This type of graph can also be known as a cumulative frequency graph. The cumulative frequency is the sum of the frequencies accumulated up to the upper boundary of a class in the distribution.
What are frequencies in maths?
Frequencies typically refer to counts, or "how many". If you wanted to know the frequencies of students in a school by gender, you would simply be asking about "how many" boys and how many girls there are.
Why are unequal class intervals sometimes used in Frequency distribution?
Because sometimes adjacent classes have to be merged so that the frequencies are not too small. This is important if anonymity is to be preserved. It is also important for statistical testing.
