This research was conducted with Korean adolescents in the Los Angeles area. Would you be willing to generalize the results of this study to Korean adolescents who live in other regions of the country? Why or why not.
Article #5 Means and SD
Ethnic Identity of Korean Americans
STATISTICAL GUIDE
T-tests produce a t-statistic. A t-statistic is comparable to a z-score. Recall how a z-score is
the difference between an individual score and the mean divided by the variability in the
distribution. The t-statistic is the difference between the two group means divided by the
variability in the two groups. The logic is the same in both: observed difference divided by
variability.
Every t-statistic has a probability associated with it. The larger the absolute value of the t-
statistic, the lower the probability of obtaining that t-statistic by random sampling error.
So t-statistics with a larger absolute value will have lower p-values. As a general rule, t-
statistics with an absolute value above 2.1 or 2.2 will be statistically significant at p < .05.
EXCERPT FROM THE RESEARCH ARTICLE'
The sample consisted of 217 Korean American students selected from ethnically diverse
high schools in the Los Angeles area. ..
Phinney's 14-item Level of Ethnic Identity subscale was designed to assess the degree of
ethnic identity among adolescents.... Items such as "I am happy that I am a member of the
group I belong to"... and "I have a clear sense of my own ethnic background and what it
means to me" [were included in the scale].
Phinney's 6-item Attitudes Toward Other Groups subscale was designed to assess
attitudes toward other groups.... Respondents were asked to rate statements such as "I like
meeting and getting to know people from ethnic groups other than my own."
A five-item checklist was developed to assess perceived discrimination. Items asked
respondents' perception of society's unfair treatment of their ethnic group and also the
personal experience of unfair treatment.... Typical items stated "During your high school
years, how often have you thought that your ethnic group is negatively stereotyped by
mainstream people?"
