Frequency distribution

Frequency Distribution is very essential for data in which we are having to count the frequency within each range. So therefore when we group data into ranges and count the frequencies within each range is known as a Frequency distribution (Mirabella, 2011, p. 1-5). In our case we have a sample of 189 women and a variable that represents the women’s ages. Moreover, the values range from 14-49, which are listed as the lower limits and upper limits. Furthermore, According to Mirabella (2011, p. 1-5) states, “That each row has consistent widths to prevent from the data being deceiving.” Therefore, after the ranges are established the frequency column should total the number of observations, when added together. Relative Frequency computes the percentages of the sample size represented by each…

easily change the column headings in the frequency distribution output. for instance, to change the current heading in cell A3 (Row Labels) to “Soft drink,” click in cell A3 and type “Soft drink”; to change the current heading in cell b3 (Count of brand Purchased) to “frequency,” click in cell b3 and type “frequency”; and to change the current heading in A9 (Grand Total) to “Total,” click in cell A9 and type…

The motion in the fastening reason for the unit might be supervised with vibration pickup and examined to determine the spectrum. These details may then be employed to set the shaker drive signal to proper spectrum shape and level. The best approach would be to arrange the machine to watch and control the amount instantly. The three functional limitations to the performance of electrodynamic shaker are displacement, velocity and acceleration. Shaker is operated by displacement at the lowest…

Polarization in Antenna Polarization is the basic thing used in transmission antennas for the propagation and reception of the signals. As we know that antenna emits electromagnetic waves in the space for the communication purposes. These two types of waves as depicted by the name Electro-Magnetic is a combination of electrical and magnetics fields. These two waves are mutually orthogonal i.e. oriented at an angle of 90o with each other. The general wave form is given as Fig: Electromagnetic…

Chapter eight of the text Sound and Recording by Francis Rumsey and Tim McCormick, discusses the principles of digital audio, and contrasts digital with analog. The text also illustrates how digital and analog work together to produce desired sound. In the world of audio there are two types; digital and analog. Analog can be described as physical or tangible in a sense, being etched onto some type of media. Digital however, is a representation of the audio waveform, which is converted into a…

Sound travels through matter, which is a solid, liquid or gas. Sound travels in longitudinal waves. There is also a vibration that starts on an object, and this causes a vibration on all the molecules. When these molecules vibrate, they cause all of the other surrounding molecules to vibrate. This vibration will spread from molecule to molecule causing sound to travel. 1. What is a wave? A wave is a chain of vibrating molecules. In general, a wave transfers energy from one place to another. 2.…

subsection{Experiment description} In order to validate this data procedure and estimation method, we carried out experiment on the ROMAC stability test rig as depicted in Fig. ef{fig2:subfig:a}. The fluid and magnetic bearing configurations were in cite{cloud2007stability}, and during the excitation process, the temperature of inlet oil was 37 ${}^{circ}mathrm{C}$. The shaft rotates at 3500 rpm, and the actuator #2 that is located at the node 47 in the FE model excited this test rig at six…

example, say that you are in a room. You hear some women to your right talking in a high pitched voice, then to your left you hear a man talking in a low pitched voice. You wonder why these two people standing in the same room are able to sound so different. This is because of both the frequency of the sound coming out of the person, and also the wave length. The frequency of a sound wave is able to have a shorter distance between its crests in a time period, the highs and lows of a wave. While…

Firstly, its advantages include being safe and painless. Unlike X-ray, MRI scanners do not use ionizing radiation; instead they use magnetic fields and radio waves which are harmless and can be absorbed by the body without causing mutations because radio waves have a low frequency and thus a low energy that doesn’t cause harm. Secondly, the pictures that are created by the MRI are precise which allow definite analysis of the image by a medical professional; especially for organs such as brain,…

they combine with the laser beam entering the instrument. In this way, the laser beam is amplified without using a high power beam at the source [1].Figure 1: The LIGO Interferometer[2]2 LIGO Laser For laser interferometers, the most important property is coherence of the laser beam. Because of this,the precision of measurement depends on the intensity and frequency noise of the source. The most common type of laser used in interferometers are solid-state lasers due to their…
