cumulative relative frequency polygon

A plot of the cumulative frequency against the upper class boundary with the points joined by line segments. Any continuous cumulative frequency curve, including a cumulative frequency polygon, is called an ogive. There are..

Cumulative Frequency Distribution - Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interval. This is explained by an example below. The following ..

There are two ways of constructing an ogive or cumulative frequency curve. (Ogive is pronounced as O-jive). The curve is usually of 'S' shape. We illustrate both methods by examples given below: Draw a 'less than' ogive curve for the following dat..

Frequency Polygon - In a frequency distribution, the mid-value of each class is obtained. Then on the graph paper, the frequency is plotted against the corresponding mid-value. These points are joined by straight lines. These straight lines may be extended in..

Identify the incorrect statement. I. The histogram is a graph that displays the data by using continuous vertical bars of various heights to represent the frequencies of classes. II. The frequency polygon is a graph that displays the data by using lines that connect po..

Let u be the frequency of a wave. That is, the number of vibrations completed by a particle in one second is u . Time taken to complete u vibrations = 1 second. . But time taken to complete one vibration is defined as the time period of the wa..

The cumulative frequency for the distribution of the distance (in miles) that 20 randomly selected runners ran during a week is given in the ogive. Find the interquartile range for the data by constructing a box plot. => 18.5, Figure 2 or 11.2, Figure 2 or 23.5, Figure 1 or 12, ..

A conjugated diene is more stable as compared with non-conjugated dienes. The relative order of stability of dienes is:Conjugated diene > Isolated diene > Cumulated diene The evidence in favour of maximum stability of conjugated dienes can be obtained from the values of heats o..

Select the correct statements: I. Pie graph is the best representation to show the relationship between the parts and the whole. II. Pareto chart is used to show frequencies for nominal or qualitative variables. III. Frequency polygon is another name for ogive. => all ..

How are the polygons ABCDE and A′B′C′D′E′ related? => cannot be determined or A′B′C′D′E′ is a reflection of ABCDE. or A′B′C′D′E′ is a translation of ABCDE. or A′B′C′D&prim..
