Statistical significance

Question 1 Cowles and Davis (2016) discussed several factors that contributed to the adoption of the .05 level of statistical significance. The first factor discussed was the discovery that computations can be utilized to measure observational error, by and astronomer, Lambert Adolphe Quetelet. This discovery led to the development of the normal distribution curve utilized today (Cowles & Davis, 2016). Following the development of the normal distribution curve, a measure of variability known…

In radiation therapy, bolus is a modality that helps compensate for differences in body contours, stop skin sparring, and to raise dose buildup on the patient’s skin (Washington, p. 171). Bolus is a tissue equivalent material, but there is not just one type of bolus. Superflab is a commercial bolus that most clinical sites use, but other bolus variations are also available for use. There is no study that compares Superflab, neon green Play-Doh, orange Play-Doh, and uncooked rice for providing…

It is well known that the temperature that a plant is grown in greatly affects the manner in which that plant grows. If the conditions are too extreme for a plant, then that plant cannot be as productive as other members of its species grown at less extreme temperatures. Such is the case of the pepper or tomato plant; if temperatures are too high for these plants, then the pollen these plants produce becomes inviable and these plants cannot successfully reproduce (Environmental Factors That……

In Willems et al’s study of proprioception deficits among athletes with high rates of recurring lateral ankle sprains, they found that almost all of their subjects tended to under shoot the needed ankle during the test (Willems et al., 2002). In this study they had 4 groups of athletes to study. The control group were individuals who had no prior ankle injuries (Willems et al., 2002). The Instability group were individuals that had suffered from more than three inversion sprains and complained…

¥ For how many students do you have Verbal Aggressiveness scores? We have Verbal Aggressiveness scores for 59 students. ¥ What is the mean for the entire sample? The mean for the entire sample is 44.0169. ¥ How do you interpret the mean score? When we interpret the mean score, we should look at the minimum and the maximum scores, so we can see the mean are close to each one. In verbal aggressiveness, the minimum is 26 and the maximum is 65, which indicates that the mean around the middle of…

In the experiment conducted by W. Scott Terry, they set out to find out whether the placement of a commercial in a set of commercials would impact the ability for a person to recall the specific commercials and specific details from said commercials. They wanted to know whether there would be primacy or recency effect when recalling information. The serial position for the capability to recall the commercials under naturalistic conditions was an important factor for how people were able to…

The questions posed should be reflective of your goals and should appeal to a large audience. Committees always want to know your potential and if you can convey your ideas effectively. Before starting, find out what most interest you, not you advisor nor anyone else. If no ideas come to mind, refer back to previous studies for ideas. Develop your questions, and don’t be obsessed about perfection; a lot of factors in field work are out your control, so try several experiments at once, and work…

2. Number of field generations: Data present in fig (1 and 2) and Table (2 and 3) indicated that the cottony camellia scale, P.floccifera has one annual generation, and these results were ensured throughout the two years of study of the insect population under field condition at Assiut governorate. The number of generations was taken from the annual number of peaks of nymphs. During the first year of investigation, the percentage of nymph population recorded 78.81%of the total population through…

Aggression 11.15 2.58 rtab (98) = 0.19 It is apparent from the table 1 that obtained value of correlation coefficient (-0.09) is less than the tabulated value of correlation coefficient (0.19). It means there is no significant relationship found between…
