The Ethics of Reading and Writing Social Research

-A review of the literature should not be biased toward supporting a particular point of view. -Research ethics is a fundamental component of social science, not a nice afterthought.

-Practice: The following list represents the scores on a mid-term exam. 100, 94, 88, 91, 75, 61, 93, 82, 70, 88, 71, 88 -Determine the mean. -Determine the mode. -Determine the median.

-Add up the values and divide by the number of cases. Summing the values yields 1001. Divide this value by 12, the number of cases. The mean is 83.4. -One value, 88, occurs more often than any other value. The mode is 88. -Reordering the cases from low to high: 61, 70, 71, 75, 82, 88, 88, 88, 91, 93, 94, 100 The two middle values of these 12 cases are both 88; therefore the median is 88.

Writing Social Research: Analysis and Interpretation

-The presentation, manipulation and interpretation of data should be integrated together

Ethics and Qualitative Data Analysis

-The subjective element in qualitative data analysis provides ad added challenge to avoiding bias in the interpretation of data. -Since the qualitative data analyst will know the identity of subjects, protecting their privacy requires special care.

Review Question A researcher studying income inequality summarizes the relationship with the following regression equation. X is the number of years of education, and Y is the personal income in dollars. Y' = 500 + 2500X Interpret the value of a (the y-intercept) and b (slope).

-The y-intercept of 500 tells us that a respondent with zero years of education is predicted to earn $500. -The slope of 2500 tells us that for every additional year of education a respondent will earn on average an additional $2,500.

Some Words of Caution
