frequency polygon for unequal classes

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 directions to meet..

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 two ways of constru..

The number of waves, which pass through a given point in one second is known as frequency. It is denoted by the Greek letter n (nu). The unit of frequency is cycle per second or simply reciprocal second (s - 1 ). A cycle is said to be completed when a wave consisting of one ..

How many unequal parts is the figure divided into? => 0 or 2 or 1 or 3..

A closed rectilinear figure having three or more sides is called a polygon..

Which of the following statement(s) is/are true? I. On a pareto chart, the frequencies should be represented on the y - axis. II. In a frequency distribution, the number of classes should be between 5 and 20. III. The three types of frequency distributions ar..

Frequency Modulation - In frequency modulation, the frequency of the carrier wave is modified in accordance with the amplitude of the modulating wave. The amplitude of the carrier remains unchanged at all times. In other words, the amplitude of the modulated wave remai..

Corresponding to w c , ( w c + w m ) and ( w c - w m ), there are three frequencies n c , n c + n m , and n c - n m . Clearly, the frequency of the unmodulated carrier wave is not changed. However, two new frequencies ( n c + n m ) and ( n c..
