A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.
frequency plot - number of counts relative frequency - number of counts/ total counts cumulative frequency - number of counts that are cumulatively summed cumulative relative frequency that are cumulatively summed. Examples: Let y = accidents per day for one week, and x = days of the week (1 to 7) y = (0, 0, 1, 2, 1, 5,1) for X = 1, 2, ... 7 frequency counts y = (0,0, 0.1,0.2,0.1, 0.5, 0.1) relative frequency y = (0,0,1,3,4,9,10) = cumulative frequency y = (0, 0, 0.1,0.3,0,0.4,0.9,1) cumulative relative frequency

Frequency refers to the count of occurrences for each category, while percent represents the proportion of each frequency relative to the total number of observations, expressed as a percentage. Valid percent excludes any missing or invalid responses, giving a clearer picture of the data that is actually analyzed. Cumulative percent sums the valid percentages progressively, showing the total percentage up to and including each category, which helps in understanding the distribution of responses.
what is the difference between a regular histogram and a percent frequency polygon
The difference between frequency polygon and line graphs is their purpose. Frequency polygons are for understanding shapes distributions, while line graphs shows information that is related in some way.
Cummulative is a misspelling. The word should be spelled cumulative.
nothing
what is density curve
The first is more commonly used and, in a usual graph, goes from bottom left to top right. The second goes from top left to bottom right. Both are equally valid.
Relative frequency refers to the proportion of times an event occurs compared to the total number of trials, typically expressed as a fraction or percentage. Cumulative frequency, on the other hand, is the running total of frequencies up to a certain point in a dataset, showing how many observations fall below a particular value. While relative frequency provides insight into the likelihood of individual outcomes, cumulative frequency helps in understanding the distribution and accumulation of data.

A periodic sentence contains a period at the end of the sentence, while a cummulative sentence contains several commas, as the latin word cummus translated into comma in 800 A.D
Frequency has a 'Q' in it.
Cumulative is formed by the addition of new material of the same kind. Comprehensive is covering completely or broadly.
Continuous refers to measurements that can take any value, possibly between two limits. Cumulative usually refers to a count "up to and including" the current value.
It shows the correlation presented between the frequency something was brought ( or what ever it is that is being measured,) and compare this to how much/ often this was sold, made, etc.
