what is the relationship between relative frequency and cumulative frequency

Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interva..

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..

Wave velocity is defined as the distance traveled by the wave in one second. Or Wave velocity = Wavelength frequency..

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, ..

De-Broglie Relationship - De-Broglie noted that according to the theory of relativity, the role played by momentum 'P' and the energy 'E' of the particle is done by angular frequency ' w ' and the propagation vector 'k' of a wave. According to Einstein relation..

Derivation of de-Broglie Relationship - The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of frequency n as: E = h n ....

The relationship may be derived by combining the mass-energy relationship proposed by Max Planck and Einstein. According to Planck, photon of light having energy E is associated with a wave of frequency n as: E = h n .....(1) According to Einstein, mass and energy are ..

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 ..

Which among the following statement(s) is/are true about histograms? I. Midpoints are useful in determining class widths and class boundaries. II. Histograms are useful in displaying cumulative frequencies. III. Histograms are used to display categorical data. IV. Histograms are..
