Frequency Data Essay

827 words - 4 pages

As a student of Saint Leo, it is our responsibility to uphold and utilize our core values. The core vale of “Excellence” states as follows, “All of us, individually and collectively, work hard to ensure that our students develop the character, learn the skills, and assimilate the knowledge essential to become morally responsible leaders” (Florida Catholic University). Using and creating opinions on data leaves one vulnerable to data fraud and other unethical qualms. In order to uphold the integrity and core value of “Excellence” we must be sure to provide accurate and honest representations of data that are provided.
When looking at the data from the following chart, one can appreciate ...view middle of the document...

Unfortunately, other than showing that the data is nominal ordinal data, we are forced to have to use simple mathematics to determine other valuable information. This information could be important when one is in a hurry to get the information provided as swiftly as possible.
Being able to quickly determine and distinguish this material can help one to make decisions quicker and more effectively. Looking at the following cumulative frequency chart, one can promptly determine the total number of grades that were examined.
Student scores on previous test (Interval, Continuous) Frequency Cumulative Frequency
100 1 1
95 1 2 (=1+1)
90 3 5 (=2+3)
80 6 11 (=5+6)
70 3 14 (=11+3)
60 1 15 (=14+1)

Charts such as the above are extremely helpful in being able to quickly break down information without much thought. If asked how many students scored an 80 or above, one can simply look at the “Cumulative Frequency” column and tell that 11 students scored an 80 or higher. Furthermore, one can quickly determine what the total number of grades that were examined by looking at the final row of the “Cumulative Frequency” column. Without having to do any form of addition, the reader can determine that there were a total of 15 scores that were examined. Finally this chart goes on to tell us that the information collected is “Continuous Interval” data at the first row and column.
Another important chart that can be made from the aforementioned data is a Relative Frequency...

Spread Spectrum Essay

1002 words - 5 pages frequency band companies can purchase to provide a wireless mobile service to customers. The term spread spectrum is used in data communications and is a technique in which the transmitted signal is distributed over a wide frequency band, much wider than the minimum bandwidth required to transfer the information. The signal distributing is accomplished by deploying a pseudo-noise code which is not directly connected to the data. The pseudo-noise code

635 words - 3 pages can be used to combat issues with interference. The use of the spread spectrum allows the 2.4GHz band to be sub-divided, providing multiple channels of various frequencies. Pseudo-random noise sequence is used to generate a list if frequencies available within the band. The data is then spread over 83MHz within the 2.4GHz band, this is possible as the frequency ranges from 2.402 – 2.480 GHz. The band is split into 79 non-overlapping channels each

2942 words - 12 pages . 2. Why to use SBR High quality and low bit rate is a constant task for telecommunication engineering. Due to the frequency band limitation of existing infrastructures, most of old coding method will delete the high frequency signal to achieve low bit rate. While the high frequency signal does no longer exist in the data and available to decode, the reproduced output signal will be either perform lower quality or not acceptable for human

Digital Audio

1062 words - 4 pages sampling, analog signals are measured in regular, equal intervals. The values of signals at the intervals are then recorded and fed into the computer through special hardware. Digital Sampling should follow Nyquist’s theorem, where the sampling frequency should be at least twice the highest frequency component in the audio signal (Marshall, 2011). Significant loss of data would be experienced if there is a low sampling frequency. This is observable in

946 words - 4 pages high frequencies that fall out of the range. Band pass filtering can be used to enhance edges (suppressing low frequencies) while reducing the noise at the same time (attenuating high frequencies). Filtering is mathematically simpler to implement in the frequency domain compared to convolution in the spatial domain [3]. Also, the frequency data reflects the geometrical structure and orientation of an image. Different shapes are usually

The mean will show me the average amount of words in each sentence, and may agree or disagree with my hypothesis. The standard deviation will show me an accurate spread of the number of letters per word, as it uses all of the data. From this I can state which paper has a more
