contained scatter, and consisted of an outlier in the sample in which the ratio of NaCl: deionised water was 10:30mL. The outlier and scatter may have been due to random errors, which caused the results to be unreliable. Due to this, the raw data does not support the hypothesis. Thus, a line of best fit was drawn in order to reduce the effect of random errors, and statistically remove the outliers, to give a better representation of what the results should have been. This line of best fit…

A weakness in this experimental design is the manual dilution of the Aquasol concentrations. This is because, if a random error were to occur, and the diluted Aquasol concentration does not result in the desired concentration, the validity, reliability, and precision of the results is majorly decreased. Whereas if the Aquasol concentrations were already previously diluted in a lab by professionals, or were bought in the correct concentrations, the reliability, validity, and precision of the…

counter-clockwise rotation. In sharp contrast, the angular displacement of D3 dimer totally distributes at the positive side (third column of Fig. 4B), representing a unidirectional counter-clockwise rotation with random step length, where the photoinduced impulsive torques are unidirectional but random in…

1  Abstract — Information sent and received in wireless communication systems can suffer from data losses due to multipath propagation, further leading to intersymbol interference. These conditions compromise the integrity of the information transmitted. This paper explores the Viterbi algorithm used to combat error bounds in convolutional codes, and develops a MATLAB-based alternative model of the algorithm for continuous time applications that is shown to significantly diminish the effects of…

outcomes were all Heads. Under the gambler’s fallacy, the person would think that the next outcome is most likely to be Tails and would then bet for Tails. The gambler’s fallacy is the false belief in “negative autocorrelation of a non-autocorrelated random sequence of outcomes” (Sundali & Croson, 2006). In simpler words, it is the tendency to perceive an outcome as less likely to occur if it occurred more frequently than normal previously. The most famous case of gambler’s fallacy occurred on…

pressure " refers to the shedding units (hidden and visible) in a neural network. By reducing a unit , we mean temporarily removed from the network, along with all of its incoming and outgoing connections , shown in Figure 1 , in which the unit is a random selection of decline . In the simplest case , each unit is maintained…

In terms of primary data, questionnaires and structured interviews were conducted to obtain quantitative and qualitative data. With questionnaires, I chose to use the simple random sampling method when distributing my questionnaires to obtain the most accurate, valid and unbiased data. Of the 30 questionnaires distributed 30 were obtained. At particular pre-selected time intervals (during school) I distributed questionnaires in sets of three to individuals ranging from twelve years old to the…

take part in the survey to represent all college freshmen. b) This is an example of a stratified random sample because the population is divided into groups, which in this case the groups would be universities, and then a simple random sample is taking from each university. c) This would be an example of cluster sampling because all colleges and universities represent the clusters and the 464 random samples of clusters are chosen and within those 464 all the first year students were observed. …

Initially, this design will involve drawing a simple random sample of communities from the Gold Coast/Brisbane city area and gathering data on levels of immigrant integration. Subsequently, a simple random sample of households from each of the aforementioned communities will be gathered in order to collect data on fear of crime and terrorism within the community. Furthermore, data…

(Kuzma 1992,6). Prospective studies are calculating the future based on the data analysis, and it is defined as a study that “examine the outcomes of event that occur in the future” (Kuzma 1992,6). 2. (5 points) A researcher wants to select a simple random sample of 100 people…
