also the outliers in the graphs in which was the thirty seven and forty nine because that was the maximum amount that people declared that they went too which was not close to all the other points that were adjacently grouped together. The standard deviation for all these plots is 7.97 in which makes the interquartile rage be interpreted in the box plot, Q1 is 6 and Q3 is 13. Some of the interferences that can be drawn would be the Q3 because of the larger points, the Q3 is then more spread…

of measurement to estimate it. Second, it provided the definition of standard error of measurement. The standard error of measurement is the standard deviation of errors of measurement, which can be expressed as the equation SEM=S_E=√(S_X^2 (1-r_(XX^ ' )))=S_X √(1-r_(XX^ ' ) ). If the test reliability is 0, SEM would be equal to the standard deviation of the observed scores; if the tess reliability is 1, SEM would be 0. In addition, different types of reliability coefficient used to calculate…

Imagery ability A pre-experiment questionnaire was administered to establish the participants’ imagery ability prior to the imagery intervention. Questions focused on how easy it is for the participant to image and the vividness of these images. For example, how easy is it for the participants to image staying positive after setbacks. This helped to control for potential confounding variables as research has shown imagery ability influences the effectiveness of imagery (Gregg, Hall, McGowan, &…

which is about five and a half times the standard deviation. This is not a normal distribution; the probability of occurrence in reality is much higher, about once every two years, which historically was 7 times over the past 14 years. In Comparison the daily volatility of China 's Shanghai and Shenzhen index of about 1.8%; A shares of the daily volatility of up to 2.75%, 7% which is equivalent to only two and a half times the standard deviation, in theory, however the probability of occurrence…

Discussion: The distribution of each graph is quite comparable as they have similar means and standard deviation, where the preferred hand has a mean of 16.33 and a standard deviation of 2.842 whilst the non-preferred hand has a mean of 17.2 and standard deviation of 2.848. The normal distribution graph of each can be seen below: Preferred Hand vs. Non-preferred Hand: The graphs and boxplots (Figures 1.3- 1.6) seen previously in the results indicate that the two results did not have a normal…

standard deviation, and variance as well as skewness and kurtosis. For example, the variable Age contained 320 valid cases, with respondents ranging in age from 18 to 35 years. The mean age was 28.02 years with a standard deviation of 4.76 years. Emailtime and Wwwtime consisted of 320 and 317 valid cases, respectively. The mean for Emailtime was 383.99 minutes spent on email per week, whereas Wwwtime had a mean of 568.57 minutes per week. Interestingly, both displayed a large standard deviation,…

lies at the lower end of the graph. This signifies that majority of the respondents have two to three adults in the household. Descriptive Analysis We calculated descriptive statistics for both the variables, including mean, median, mode, standard deviation, variance, range and many more. Further, we determined an appropriate measure of central tendency, based on the distribution displayed by graphs. We also mentioned an appropriate measure of dispersion based on the type of variable and shape…

different delays and 2 different reward magnitudes, whereas the present version only asked 6 questions in total, which is why results for this test was not included in the main article. Supplementary Results Table S3 presents the means and standard deviations of proportions of delayed choices according to condition (gain vs. cost), smoking status, and AUDIT status. Proportions of responses have been found to…

It was hypothesized that a stressor would cause abnormal activity in the brain and the secretion of hormones, resulting in fewer words recalled by condition B compared to condition A. The means and the standard deviations of the two conditions suggest that participants in condition A performed superior to those in condition B. This difference is reasonable, considering that participants in condition A were mentally preparing themselves to memorize the word list so…

specific, it is a practical method to express the relative frequency of questionnaire responses. Mean is used to describe the central tendency of all data (Manikandan, 2011). The standard deviation is used in conjunction with mean. Specifically, the mean measures the center of the distribution, while the standard deviation measures the spread of the distribution (Baillie, 1992). By compared with mean, the results of SD will show how spreads out the numbers are. The correlation is a statistical…
