What is a cumulative frequency polygon?
By its very nature, measuring cumulative frequency on either axis of a graph will produce a continuing line on the opposite axis. Therefore, it is impossible to construct a closed frequency polygon when dealing with cumulative frequency.
What is cumulative frequency?
Cumulative frequency is the running total of class frequencies.
When should you draw a straight or curved line in a cumulative frequency graph?
You should draw a line as straight as a rainbow with cheese.
What is difference between a less than cumulative frequency with a greater than cumulative frequency?
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.
Why does a cumulative frequency graph never go down?
Because of the word "cumulative". What that means is that the height of the graph for any value (X=x) is the number (or proportion) of observations that were less than or equal to the value x. Now consider the cumulative value of the graph for a value of X which is bigger than x. All the previous observations were ≤ x and so they will be ≤ the newer, larger value. So the height of the cumulative graph cannot decrease. It may increase if there are any observations whose value was between x and the new value.
What does cumulative frequency graph measure?
a cumulative frequency graph mearsure the cumulative frequency on the y-axis and the class boundaries on the x-axis
Is an ogive a graph of cumulative frequency distribution?
yes. An ogive is also known as a cumulative frequency graph.
Is a histogram a graph that represents the cumulative frequencies for the classes in a frequency distribution?
No it is not. The ogive is a graph that represents the cumulative frequencies for the classes in a frequency distribution.
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.
The graph of a cumulative frequency distribution is called?
ogive
What is another name for the ogive?
cumulative frequency graph
How do you find cumulative frequency?
By adding up the (one by one,) the frequency total in order to find the cumulative frequency, most commonly, you just then plot this on a cumulative frequency graph or box plot.
What is cumolative frequency curve?
A cumulative frequency curve is a graph that shows the cumulative frequency of a data set. This type of graph can present data, such as medians and quartiles. Another name for this curve is an Ogive.
What is the difference between a cummulative frequency graph and a cumulative frequency polygon?
A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.
What is five letter name for cumulative frequency polygon?
graph?
What is a cumulative frequency polygon?
By its very nature, measuring cumulative frequency on either axis of a graph will produce a continuing line on the opposite axis. Therefore, it is impossible to construct a closed frequency polygon when dealing with cumulative frequency.
What is the definition of 'ogive'?
In Architecture, a pointed or Gothic arch. In Statistics, a cumulative frequency graph.
