relative frequency table

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..

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

Frequency Distribution - A teacher gave a test to a class of 26 students. The maximum mark is 5. The marks obtained by the pupils are: Such data as above is called ungrouped (or raw) data. We may arrange the marks in ascending or descending order. The data so represented is called an arra..

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 both dire..

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 frequency distribution table gives the marks o..
