...Regression Analysis Definition: Regression is used to examine the relationship between one dependent and one independent variable. After performing an analysis, the regression statistics can be used to predict the dependent variable when the independent variable is known. Regression goes beyond correlation by adding prediction capabilities. Types Of Regression Analysis: Most widely used two types of regression analysis are- I [pic] Linear Regression Analysis: When the regression is conducted by two variables or factors then is called linear regression analysis. Multiple regression analysis: Multiple regression analysis is a technique for explanation of occurrence and calculation of future actions. A coefficient of correlation among variables X also Y is a quantitative index of connection involving these two variables. In squared type, while a coefficient of purpose specifies the quantity of difference in the principle variable Y that is accounted for through the deviation in the analyst variable X.

...assistants, and the like - but that it's really about customers.” Cellphones has changed us socially in many different ways, video chat, and text messaging, and keeping contact through different social networks wirelessly. Cell phones have changed the way people socially interact with each other. Nowadays, anyone anywhere can just pick up their cell phone and call each other at any time of the day or night. (Stewart 1). In the past when there were just house phones around, people could use the excuse “Sorry I wasn’t home to answer your call” but now, with the emerging of cell phones, people will get a hold of you somehow. Cell phones are considered to be your own personal property while house phones are considered to be used for the family. Cell phones depend on satellite and signal, which means anyone, can take their cell phones anywhere they choose, while house phones depend on the wires in the house which limits anyone from using it outside of the house. (Stewart 1). For example, someone could be on their house phone and their little brother could be eavesdropping on the conversation. No one would want that, would they? On the other hand, cell phones are more personal and most of them have Wi-Fi which leads them to be connected to the internet. Now people are more socially involved on the web through Facebook, Twitter, Instant Messaging, etc. However, cell phones have both a positive and negative effect on people. Cell phones are very convenient to the point where it has...

...Almost every teen that you encounter has a cell phone nowadays. Among those with cellphones, almost 90% are texters. Of those who text, 30% send over one hundred texts per day. That adds up to be more texts per day than there are people on the planet. Wow! Of all the time spent driving, the chances are that someone will receive a text while driving. The law passed in the last few years has made sending a text while driving illegal.Texting is a distraction for the driver. It affects the driver as much as the impairment of the effects of alcohol. It was recorded that there were at least 200,000 accidents due to drivers who were texting. This is the main reason that the law prohibiting texting was passed. Even if an accident does not occur, several drivers may be unfocused and breeze through an intersection when a light is red. In general, distractions impair driving and are being fixed to the best of the state’s ability.True, distractions are bad and need attention. Yet there are still so many distractions at hand such as: adjusting the air-conditioning, turning radio knobs, opening/closing windows, changing CDs, talking on a phone. Why has nothing been done about these nuisances? Are these not just as bad of hazards as that of texting while driving? A fix should be assigned to each of these issues also since if they are as bad as texting.However, texting is a useful tool for communication. It is just as important as a phone call. Readers are right, if they think that texting and...

...cell phones should not belong in schools. There are many advantages and disadvantages of owning a cell phone. However, many students who own cell phones use them for the wrong reasons. Cells phones should not be allowed within schools to be used by students because they cause distractions, provoke cheating, and can be used for illegal purposes. Distractions Cell phones have many features and abilities that allow students to communicate, socialize etc. This leads to distraction and less concentration from students in school. The most significant feature of cell phones that leads to distraction is texting. Statistics verified that teens with cell phones send 440 text messages a week and 110 of those texts happen in the classroom. Text messaging has become the “future” method of passing notes in school. Examples of students’ texting in class, often behind the teachers back, will make the child lose out on the learning opportunity and affect their studies which soon lead to lower grades. Even if cell phones are not being used by the students, a cell phone that is not off and rings during class time, disrupts the whole class and forces the teacher to stop teaching, wasting valuable learning time. A recent survey has established that cell phones do not provide students with assistance in their education. Everyone who answered the survey agreed that cell phones do not provide students with assistance in their education, nor do they help them concentrate in class, and cause distractions...

...Introduction Today mobile communication is playing a major role in the modern society. Sri Lanka has made rapid progress in information and communication technology in recent time. There are 12.8 million mobile phone users and 3.8 million fixed line phone owners among the country’s total population of around 22.8 million. Majority of the mobile and CDMA customers use prepaid connections. Therefore mobile reloads or recharge cards is a major necessity. Currently there are five mobile service providers as well as several CDMA providers. These companies use different recharge cards with different PIN numbers. Therefore those companies have to produce and distribute them separately. We understood this as a problem and as a solution we are suggesting a way to recharge all the networks from one card. This will reduce the distribution cost of those companies as well as customers also get benefit from it. Anyone can buy these cards from the various price ranges similarly to normal recharge cards and they can recharge their phone without considering their network. Some shops sell only selected types of cards from networks. Customers have to find their cards of their network here and there. This new system will provide answers for these problems. Project description • Issue a card with a specific PIN available in various price ranges to the customer. • PIN numbers are issued from the created database. • A dongle is connected to computer and customer sending...

...It is dangerous both through anecdotal and hard scientific fact. The distraction of texting, twitting and answering a call is the main cause of accident on the road. Be responsible for someone’s life, put down the phone Introduction The weight of scientific evidence to date suggests that use of cellphone while driving does create a safety risk. Excess use of the cellphone can cause accidents because the driver might run through a stoplight and into oncoming vehicles, knock down pedestrians and or cause fatality towards their self. According to the National Transportation Safety Board (NTSB), “distracted driving is becoming the new DUI; it is becoming an epidemic.” This epidemic is causing the life of millions per year worldwide. If we all take that stand to safety and switch off phones while driving the life saved might be your owe., The main cause of distraction while driving is the use of texting on the cellphones; even though the call or text is essential and the lost of a client or business venture maybe the outcome. The best suggestion would be for the person to get off the main road and find a parking lot or emergency lot, and then check the message, but that will not be followed, so the safes way is to ban cellphones use. In calling for a ban on all use of electronic devices while driving, the NTSB cited a series of fatal accidents in which were deemed distractions. In 2004, a bus driver using his hands-free cellphone struck the underside of an arched stone bridge on the...

...Wilson, Emily McPeake ENG 1A September 21, 2013 How Is Evolution Killing the English Language? Texting has become one of the most common forms of communication in modern times, especially with the younger generations. As the times and definitions of “modern” continues to change, many people are having troubles coping with this concept and the fact we are and will always continue to evolve. Just as growing up is the human body’s way of changing, language is societies way of changing. There is no set definition of what the English language is supposed to be composed of, forever. The English language is not negatively impacted by texting; it is simply evolving through new forms of communication, entertainment, and learning. Our way of communicating with each other has been transformed with the help or “txtspeak.” It is a very common way of talking, whether it’s in person or through SMS. If we compare what we considered to be the language of English from a few hundred years ago to now, there is an obvious change. As we evolve as a society, everything around us does as well. Abbreviations are being entered into the dictionary and many people are going crazy over it. One of the most common complaints about our overuse of abbreviations is the multiple meaning of them. Humphrys claims that, “as it has developed, its users have sought out increasingly obscure ways of expressing themselves.”(Humphrys, 187) Even though this seems to be true, the trick to figuring out the meaning...

...one time. For instance, one could be chatting with a friend online while listening to music and doing homework. Although multitasking can indeed be helpful in completing tasks in a timely matter, one must recognize the definite price that is being paid for this practice. Media multitasking is damaging today’s students by not only hindering one’s ability to fully absorb information, but by changing student’s understanding of what the term socializing means. In order to fully understand how media multitasking is damaging students, we must first realize what exactly is happening in the brain during multitasking. Those students who multitask during homework may be doing things such as browsing Facebook, checking email, texting, and instant messaging. Scientists believe that when a person is trying to complete multiple tasks like this, the brain is distributing low amounts of information to each task instead of concentrating on one task at a time. This creates a sort of “brownout” effect inside of the brain. University of Michigan Professor David Meyer states that “all the lights go dim because there just isn’t enough power to go around.” This means that even though you think you are giving most of your attention to that homework assignment, your brain is actually rationalizing instead. During this rationalization, the brain is simply distributing a low dose of focus and concentration to your homework assignment, and an equal amount to your social life on facebook. As a result of...

...Daniela Gomez Professor O’Rourke English 1B 20 March 2013 First Step: Denial Take a minute to think back, back before today started, back before this week started, and, how about, back before this year started. Do you remember just about what was going on at the time? It is unlikely that any recognition of the past would flash back to your memory unless it was monumental or important. However, one thing you would be able to retrace is whom you were talking to at the time, and even what you were talking to them about. With todays technology it makes it very easy to relive past conversations and go back to recorded moments. With modern day advances, individuals hold the ability to be able to capture a moment at anytime and share it around the world with whom they choose. We are also able to play games, entertain ourselves, see others, and talk to our friends at a single push of a button within just a couple of minutes. Technology continues to grow within industries making it easier to communicate and stay organized all due to a tiny handheld gadget. The better the technology the easier it is for people to stay connected with each other. Although there have been several groundbreaking inventions in history, it is noticed that the cell-phone has had a noticeable impact on society, especially among todays youth. With children now gaining access to a variety of these devices it is apparent that many lack basic elements in communicating. With a participant group of roughly...

...A study by the Virginia Tech Transportation Institute, along with prior studies by Liberty Mutual Insurance and state-funded organizations located online, reveals the shocking statistics of texting behind the wheel: Texting while driving increases the risk of accident 23.2 times over unimpaired driving. Texting while driving results in longer response times than even drunken driving. While an unimpaired driver can respond quickly to changes in traffic and begin braking within half a second, a legally drunk driver needs four additional feet to begin braking—and a driver who’s texting needs 70. In the moments before a crash or near crash, drivers typically spend nearly five seconds looking at their mobile devices—enough time at typical highway speeds to cover more area than the length of a football field. Though 95 percent of drivers surveyed said texting behind the wheel was unacceptable and unsafe, at least 21 percent admit to doing it anyway. Especially amongst teens, texting results in erratic driving behavior, like lane weaving and speeding up and down, increasing the likelihood of hurting pedestrians and running into other vehicles. Texting behind the wheel is generational: 37 percent of drivers 18 to 27 admit to texting while driving, compared to 14 percent of 28 to 44 year olds, and 2 percent of 45 to 60 year olds. An accident can happen in two to three seconds while texting. (Noyola, 2/28/2012) (Kiesbye, 24 February 2012) With dangers like these in mind,...

...How Social Networks Effect Our Daily Life Today, many people are highly active on social networking sites. According to the study, more than 150 million people use Facebook to keep in touch with friends, share photographs and vedios and post regular updates of their movement and thoughts. A further six millon people have signed up to Twitter, the micro-blogging service that lets users circulate text messages about themselves. Some people think that social networks are dangerous and they aren’t real. In my opinion, social networks are good because they make our life more convenient in three ways, such as many people use social networks to keep in touch with friends, promote their product as a seller or affiliater and play games. First, social networks let us keep in touch with friends. People can present their personal information and thoughts for anyone to see. Besides, we can find our old friend that we separate for a long time. Even though we don’t meet frequently, we can know our friend’s life and their status by social networks. Although the social networks change the ways to make friends, it is more convenient to keep in touch with our friends in busy life. We can share our information wherever we are. Therefore, the social network is a good way to contact with friends in modern times. Second, social networking sites are good for business. Some employers encourage their employees to use social networks to build relationships and closer link with colleagues and customers...
