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…

our sample size for each run. The MSER technique used various truncation values (d*), minimizing standard error, for each of the 10 runs. The resultant point estimates are independent, but based on various sizes of n. To prevent introducing bias into our results, we weighted each estimate by n. A histogram was generated using x ̅, weighted by n, seen in Figure 7. Note that our standard deviation was extremely high. To minimize the variance of our mean, we calculated a new weighted average…

Smaller sample sizes result in larger standard deviations with a flatter and more spread out distribution. This results in greater estimates of standard error. This is a problem. Slide 7: Let’s talk about beer. Yes, beer. W.S. Gossett, a scientist for Guiness brewery, pondered how each bale of barley affected the quality of the beer produced…

where we took the readings in centimeters. We wrote down all our readings in Excel and found the confidence intervals. From the observations, we find that the data is more accurate for normal vision than impaired vision because for the standard deviation for normal vision is far lesser than impaired vision. This means that the value for impaired vision are more dispersed and has more errors. There are certain errors on this experiment too. This is because, both the normal and impaired…

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…

variables in thirty two countries that were randomly chosen. In the table provided, you will see the average, median, standard deviation, maximum, and minimum of the given set of data. All information provided below was taken from World Bank 2007 database and calculations were calculated using the SPSS software: Descriptive Statistics N Range Minimum Maximum Mean Std. Deviation Agriculture, value added (annual % growth) 28 27 -11 16 2.96 5.928 Foreign direct investment, net inflows (% of GDP)…

Association between Work Motivation and Job Satisfaction of College Teachers is an article that was written in 2012 by Sarita Maharjan. In that article, the author publishes the findings of her study on the relationship between work satisfaction and the job satisfaction of teachers in Nepal. She begins by explaining the background of her study. Maharjan highlights numerous studies that have been conducted by different researchers about the topic. Basing on those past research studies, she…

data 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…

Introduction The dynamics of hospital performance are often associated with effective patients’ care and length of stay (LOS). In this case study, the hospital governance is strategically seeking to reduce LOS in the inpatient setting at four of the system 's hospitals. Generally, we will conduct analyses of the data set that have been provided to identify the hospital that is achieving the lowest LOS using descriptive statistics. Statistical Analysis: Length of Stay Each hospital in the…
