Research-Supported - Essay Example It is therefore because of this reason that this study is aimed at discussing influences of modern technology on the children development (Internet, cell phones, TV). Presents two lines of thought where admirers of modern technology argue that it ensure swift communication and quick receipt information. Opposing side believes that technology affects cognitive and physical development of children. Modern technology is usually accredited to the Internet, cell phone, computers and television among others. The entire above mentioned are summarized as a civilization that is swift, communication rich, information and on the screen. For that reason, it is difficult for children today to imagine a life without computers, the Internet and cell phones. Numerous researchers have, thus, differed concerning the effects of technology on the growth of the contemporary kids. Some believe that technology is the advanced level of human life while others contend that technology has diverse effects on brain development. Presently, children are immersed in technology. Many children today, envisioning a life without technological gadgets is like living in the senior generation, and it is difficult for kids to imagine living in the aged generation. This is because technology has eased all aspects of life. However, in spite of increased use of technology among children, technology has both positive and negative influences which if not observed well, can lead to immorality all over the modern children. It is therefore because of this reason that this study is aimed at discussing influences of modern technology on the children development (Internet, cell phones, TV). Technology refers to advancement in scientific knowledge utilized for practical purposes, mainly in industry.

Property Prices in the UK - Coursework Example Our null hypothesis and alternative hypothesis were as follows:H0: ÃŽ ¼w = ÃŽ ¼l (No significant difference in the two means) H1: ÃŽ ¼w ≠  ÃŽ ¼l (A significant difference exist between the two means)A t-test was used to ascertain whether the price data vary vastly, with regard to our assertion or it is steady. We opted for a t-test because, according to Dalgaard (2008), it is best suited for this work and it is easy to interpret. From the results of two sample, t-statistics tells how the mean of one population sample deviates from the mean of another population sample. It interprets the average of each property price and the mean difference between the two property sits. Moreover, t-test gives an explanation as to whether the difference in mean is statistically significant or not especially if the two populations, where the sample prices were gathered, have similar means.      We tabulated the sample prices for property news (sample w) and the sample prices for property live and then calculated the relevant summary statistics using STATA.  The variance of difference for the two means (sd2) was calculated as follows:sd2 = (sw2 / nw) + (sl2 / nl) = (108370.3/8) + (108725.4/7)  = 13546.29 +15532.2 sd2 = 29078.49 Therefore, sd = √29078.49 = 170.52 Our calculated t-statistics was therefore given as:  t = (ÃŽ ¼w – ÃŽ ¼l)/ sd = (85731 - 73329.71)/ 170.52 = 72.73 However, the tabulated t-value, at 13 degrees of freedom (8 + 7 -2) is given as 1.7709. Since the calculated t-statistics > the tabulated t-statistics, we reject Ho and conclude that the two means for the two property prices are significantly different at 5% significance level.
