Exam 10: Analysis of Quantitative Data

Talk about: -percentile

Talk about: -frequency distribution

Refer to the following paragraph to answer the questions below. Researchers debate the degree to which racism is a major source of white anti-immigrant attitudes in the United States, since most recent immigrants are non-white. To examine this relationship, I used a measure of racial prejudice among whites not wanting a black person to marry a close relative and cross-tabulated it with an opinion question about immigration using data from the 2000 General Social Survey. The variables are percentaged both by row and by column. MARRY BLACK: How would you respond to a close relative marrying a black person? Strongly Favor, Favor, Neither Favor or Oppose, Oppose, Strongly Oppose. IMMIGRANTS: Should the number of people coming from other countries to the U.S. as immigrants be Increased, Stay the Same, or Decrease? Data only for Race = White, GSS 2000. Note: Missing data, Don't Know, No Answer removed from Table. Immigrant response collapsed into three categories. Increase At lot and Increase a Little combined into Increase, Same, Decrease a Little and Decrease a Lot are combined into Decrease. Column Percentage -Looking at data from the above two tables, which of the following is FALSE?

Talk about: -replication pattern

Talk about: -cross-tabulation

Talk about: -partials

Talk about: -descriptive statistics

Talk about: -z-score

Talk about: -normal distribution

Talk about: -statistical significance

Someone says, "It is statistically significant at the .10 level." What does it mean? Is a Type I or a Type II error more likely if a .05 level had been used? Explain.

Talk about: -mode

Discuss the concept of control as it is used in trivariate analysis. In what ways it is similar to or different from control in experiments?

Refer to the following paragraph to answer the question below. With slight modification, the following tables appeared in Cernlo, Karen. 1993 "Symbols and the World System: National Anthems and Flags," Sociological Forum 8:243-71. The tables represent critical empirical evidence in the study. Dr. Cernlo studied how types of nations in the world system relate to the type of flag they have. She divided nations into two categories according to world system theory (core/non-core) and three categories according to modernization theory (pre-modern, modernizing, postmodern). She divided flag design, her dependent variable, into a basic or embellished graphic syntax. -Which of the following conclusions is correct? (Note that one of these statements is a close paraphrase directly taken from her article, the others are alternative, opposing hypotheses she was testing.)

Talk about: -range

Refer to the following paragraph to answer the questions below. The infant mortality rate (number of infants who die in their first year per 1,000 births) has a mean for the OECD (most advanced industrial countries) of 8 with a standard deviation of 1. -The infant mortality rate in the U.S. is 9 infant deaths per 1,000 births. The rate for Ireland, Singapore, Hong Kong, Netherlands, France, Canada, Germany, and Switzerland are all the same. Their rate is 2 z-scores below that of the U.S. What is their rate?

Talk about: -standard deviation

Talk about: -contingency table

Talk about: -control variable
