Extracted text: Asian Values STATISTICAL GUIDE The amount of variability in a distribution is a very important feature of a distribution. It's so important, in fact, that it has multiple names, like dispersion or spread. The standard deviation(SD) is a yardstick for measuring variability in a distribution. If the standard deviation is small, the scores in a distribution will mostly huddle close to the mean. If the standard deviation is large, the scores in a distribution will be more widely dispersed from the mean. In fact, you can think of the standard deviation as the average amount scores differ, or deviate, from the mean. In a normal distribution (i.e., a type of symmetrical, bell-shaped distribution), 34% of cases are within one standard deviation above the mean and 34% are within one standard deviation below the mean. For instance, if the mean equals 50.00 for a normal distribution and one standard deviation unit equals 10.00, then 34% of the cases lie between 40.00 and 50.00, and 34% lie between 50.00 and 60.00. Thus, 68% of the cases lie within 10 points of the mean (i.e., 68% lie between 40.00 and 60.00). EXCERPT FROM THE RESEARCHARTICLE! This study was conducted at a Chinese community center in a southwestern city of the United States ... A convenience sample of youths aged 14 to 18 years old was recruited via posters and word of mouth at the center's after-school volunteer program and Chinese-language school for high school students. The AVS [Asian Values Scale] uses a modified Likert-type scale in which 1 = strongly disagree, 2= moderately disagree, 3 = mildly disagree, 4 = neither agree nor disagree, 5 = mildly agree, 6 = moderately agree, and 7 = strongly agree. Scores were based on responses to 36 statements written at a middle school reading level. The six Asian cultural values themes explored were (1) collectivism, (2) conformity, (3) emotional self-control, (4) family recognition, (5) filial piety, and (6) humility. Each statement in the scale reflected one of the above themes. Using the AVS as a continuous scale, scores for level of adherence to Asian values can range from 36 to 252; those with lower scores demonstrate a lower adherence to Asian values, whereas those with higher scores demonstrate a higher adherence. Fifty-two youths were interested in participating in the study, and 31 youths completed the entire study. The most common reasons for nonparticipation were the time commitment and lack of interest. AVS scores for the study population ranged from 109 to 206; the mean score was 155.1 (± SD 20.7), and the median score was 152. For boys, the mean score was 152.7 (± SD 17.6), with a range of 109 to 176

Online Discussion Questions (Choose one of the following). 1. The researchers state that they used a "convenience sample." What is your understanding of the meaning of this term? Is such a sample the best type to use in social science research? Explain.10. 2. Does the fact that only 31 of the 52 youths completed the study affect your confidence in the results of this study?
