Along with descriptive statistics such as averages, ranges of values, and percentages or counts, the chart of a frequency distribution puts you in a stronger position to understand a set of people or things because it helps you visualize how a variable behaves across its range of possible values.

Answer: Advantages of representing a function as an equation instead of graph : No chance of misinterpretation of the data as making graph involves more data as compared to data needed to represent function as an equation. Drawing graphs may be inconvenient in case you need to plot fraction and decimal functions.

You can only squeeze in a small number of columns before the table width causes horizontal scrolling on smaller screens. Making columns narrow to prevent horizontal scrolling will decrease readability of text in cells, as a paragraph is stacked into one or two words per line. Page size is increased vs.

whereas few disadvantage are as follows.

• sometimes they just cant be solved without a calculator.
• It may result in misconceptions (e.g. the concept of similarity carries different meanings in mathematics and the real world).
• Makes abstract thinking difficult, some topics should remain abstract.

The advantage of using frequency distributions is that they present raw data in an organized, easy-to-read format. The most frequently occurring scores are easily identified, as are score ranges, lower and upper limits, cases that are not common, outliers, and total number of observations between any given scores.

The total number of waves produced in one second is called the frequency of the wave. The number of vibrations counted per second is called frequency. Here is a simple example: If five complete waves are produced in one second then the frequency of the waves will be 5 hertz (Hz) or 5 cycles per second.

At high volumes, infrasound can directly affect the human central nervous system causing disorientation, anxiety, panic, bowel spasms, nausea, vomiting and eventually organ rupture, even death from prolonged exposure. The first documented attempt to reproduce the infrasound effects was by Vladimir Gavreau in 1957.

Especially dangerous is infrasound at the frequency of 7 Hz, since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity. Machines, natural sources storms, earthquakes, hurricanes, etc. generate infrasound.

The healthy human ear (children/young adults) can hear sounds from 50Hz anywhere up to 20KHz although there is little that is useful above 8KHz and the human voice rarely exceeds 4.5kHz. The hearing ability of a dog is dependent on its breed and age.

Frequency 528, relates to the note MI on the scale and derives from the phrase “MI-ra gestorum” in Latin meaning “miracle.” Stunningly, this is the frequency used by genetic biochemists to repair broken DNA – the genetic blueprint upon which life is based. It repairs the DNA.

Benefits of Music based on 7 Solfeggio Frequencies

• 396 Hz Solfeggio Frequency. Healing sound frequency 396 Hz has beneficial effects on feeling of guilt.
• 528 Hz Solfeggio Frequency.
• 639 Hz Solfeggio Frequency.
• 741 Hz Solfeggio Frequency.
• 852 Hz Solfeggio Frequency.
• 963 Hz Solfeggio Frequency.

432 Hz. In Pythagorean math, 432 reduces to 9, while 528 reduces to 6. Though different, we see in the Solfeggio frequencies the harmonization between 6 and 9 (along with 3). In short, 432 Hz resonates with the very vibrations of our planet, which is one of the reasons it’s so beneficial.

Due to more harmonic and pleasant nature of 432Hz music than 440Hz, it helps in the release of serotonin and endorphins, which in turn keep the blood pressure and heart rate stable. 4. 432Hz Music helps in releasing the negative energy blockages and acts as a good sound healing tool to release toxins.

75M Hz

EMFs of 0–300 Hz are defined as ELF-EMFs. We are exposed daily to 50–60 Hz ELF-EMFs produced by most electrical home appliances [1, 2]. Several epidemiological studies have suggested that ELF-EMF increases the risk of developing cancer, including leukemia, brain, and breast cancers [3–5].
