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 ..
Ogive (Cumulative Frequency Curve)
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..

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 ..

In frequency modulation, the deviation of the carrier frequency from its average value is proportional to the instantaneous amplitude of the modulating signals. When the signal voltage is zero, the carrier frequency is unchanged. When the signal approaches it..

Experiment to determine the frequency of a tuning fork using a sonometer (absolute method)
. When it is at rest, on placing the vibrating tuning fork on the sound box, the paper rider is found to vibrate vigorously and may be thrown off. The resonating length AC = L is measured using a metre scale. The experiment is repeated by gradually increasing the load W 2 in steps of 1Kgwt. The rea..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
