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.
Given a frequency table,the first cumulative frequency is the same as the first frequency;the second cumulative frequency is the sum of the first cumulative frequency and the second [ordinary] frequency;the third cumulative frequency is the sum of the second cumulative frequency and the third [ordinary] frequency;and so on.An alternative definition is that the cumulative frequency for any value is the sum of all the frequencies less than or equal to that value.
Data representation. Cumulative frequency is the sum of all previous frequencies.
Cumulative frequency is found by adding the frequency of each class interval to the sum of the frequencies of all previous intervals. To calculate it, you start with the first interval, where the cumulative frequency is simply the frequency of that interval. For subsequent intervals, you add the frequency of the current interval to the cumulative frequency of the previous interval. This process continues until all intervals are accounted for, resulting in a cumulative frequency distribution.
A cumulative frequency distribution shows the accumulation of frequencies up to a certain point in a dataset, allowing for the visualization of how many observations fall below a specific value. It helps in understanding the distribution of data, identifying percentiles, and analyzing trends. This type of distribution is often represented graphically with a cumulative frequency curve, which can highlight the proportion of data below various thresholds. Overall, it provides insight into the overall distribution pattern of the data.

No it is not. The ogive is a graph that represents the cumulative frequencies for the classes in a frequency distribution.
Cumulative Frequency is The total of a frequency and all frequencies so far in a frequency distribution. It is the 'running total' of frequencies in the frequency distribution table.
Cumulative frequency refers to the running total of frequencies in a frequency distribution. It shows the number of observations that fall below a certain value in a data set. Each cumulative frequency is the sum of the corresponding frequency and all frequencies below it.
By definition, the sum must be unity.
According to Anderson, Sweeney Williams book Essential of Statistics For Business and Economics, 4e Edition, 2006 p. 34 cumulative frequency distribution is "a variation of the frequency distribution that provides another tabular summary of quantitative data." In simple terms, the cumulative frequency distribution is the sum of the frequencies of all points or outcomes below and including the current point.
Not directly, but the cumulative frequency contains the same information as the frequencies for the values in question. However, it may not show the full details of the distribution if the values have been grouped.
Cumulative frequency is the running total of frequencies within a given dataset. It represents the sum of frequencies up to a specific point in an ordered distribution. It is useful for analyzing the total number of observations that fall below a certain value in a dataset.
Given a frequency table,the first cumulative frequency is the same as the first frequency;the second cumulative frequency is the sum of the first cumulative frequency and the second [ordinary] frequency;the third cumulative frequency is the sum of the second cumulative frequency and the third [ordinary] frequency;and so on.An alternative definition is that the cumulative frequency for any value is the sum of all the frequencies less than or equal to that value.
Yes.
