frequency distribution classes

Edward took 16 mock tests. In 3 of the tests, his score is average. In 2 of the tests, his score is above average and in 5 of the tests his score is below average. In the remaining 6 tests his score is good. Which frequency distribution is appropriate for his test scores? => Tab..

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..

The number of oscillations of a particle executing SHM in one second is called the frequency. It is the reciprocal of the period i.e., n = 1/T. It will be equal to the number of revolutions completed per second by the body on the circle of reference. Its unit is cycles per second or hertz..

The frequency distribution for the time (in minutes) spent per day on the computer by 400 employees in a company is shown. I. Find the percentage of employees who spend atmost 600 minutes per day on computer. II. Find the percentage of employees who spend atleast 500 minutes but..

A jewellery store sells gold chains, pendants and bracelets. The cost of 24 different gold bracelets (of the same weight) are $150, $100, $150, $200, $150, $100, $150, $100, $150, $100, $150, $100, $150, $100, $150, $200, $100, $150, $150, $100, $150, $200, $150 and $200. Make a frequency..

Find the frequency of the number 5 from the frequency table. => 1 or 5 or 8 or 6..

Poisson Distribution - Poisson distribution is a limiting process of binomial distribution. Poisson distribution occurs when there are events which do not occur as outcomes of a definite number of outcomes. Poisson distribution is used under the fol..

Poisson distribution is a limiting process of binomial distribution. Poisson distribution occurs when there are events which do not occur as outcomes of a definite number of outcomes. Poisson distribution is used under the following conditions: Number of tria..

Geological Distribution - The organisms show particular patterns of distribution on earth. The distribution of the species give an indication of how the earth was earlier. It is believed that the earth was a single mass called the Pangea. It consisted of two large cont..
