frequency distribution frequency

Wavelength, Frequency and Time Period - Wavelength, frequency and time period describe a wave. Now let us define these terms. Wavelength is defined as the distance between the two nearest points on the wave or it can be defined as the distance between two consecutive crests or t..

Question 11 - Question: Frequency of a wave motion is 250 Hz. What is its time period? Answer: Frequency ( ) = 250 ..

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..

The fundamental mode of vibration of a stretched string is shown in the figure. It has two nodes at the ends and an antinode in the middle. If L is the length of the vibrating segment between the two nodes, th..

Various electrical machines and noises cause amplitude disturbance in the transmission of amplitude-modulated wave. This makes the reception nois..

In a Botany experiment the lengths (in mm) of 30 leaves measured are as indicated. Choose a table which shows the frequency distribution of the data. => Table - 1 or Table - 2..

Using the histogram, construct a frequency polygon. => Graph 1 or neither Graoh 1 nor Graph 2 or Graph 2 or both Graph 1 and Graph 2..

Hundred digits were chosen at random from a set of tables. The frequencies of the digits were: Digit 0 1 2 3 4 5 6 7 8 9 Frequency 8 7 13 10 12 14 8 7 9 12 At level of significance α = 0.05, find the chi-square test value and check if the digits distributed are i..

The frequency distribution represents the data obtained from a sample of computer repairs. The values are the mean time (in hours) between repairs on 80 machines. Mean time between repairs Number of machines 25.5 - 28.5 5 28.5 - 31.5 9 31.5 - 34.5 32 34.5 - 37.5 20 37.5 - 40.5 1..
