I need help with these questions:

1.

The numbers within the cells in the following "crosstab" table represent what? EVER BEEN DIVORCED 0R SEPARATED ' CONFIDENCE IN CONGRESS Crosslabulation Count CONFIDENCE IN CONGRESS A GREAT DEAL ONLY SOME HARDLY ANY Total EVER BEEN DIVORCED YES , 168 OR SEPARATED N0 . 523 Total - - Standard deviations Means Frequencies Chi2 Statistics Expected values Which measure of central tendency would be most appropriate for a social class variable (e.g., chronically poor, working class, lower-middle class, upper-middle class, and upper class)? Mode Median Mean None of the above What is the difference between variables and cases? Cases must contain data about individual people Variables allow only one potential value in a dataset There are always more cases than variables in a dataset Variables are observations of different phenomena measured at the same unit of analysis Cases typically have 24 cans of beers or '12 bottles of wines What percentage of cases in a normally-distributed sample ought to fall within :1 standard deviation of the mean? 99% 95% 68% None of the above (i.e., this must be a trick question) \fWhich measure of central tendency would be most appropriate for a race/ethnicity variable (values including American Indian, Asian American, Black, Hispanic/Latino, and white)? O Mode O Median O Mean O None of the aboveWhat is the primary difference between the variance and the standard deviation? The variance is equivalent to the square root of the standard deviation Variance is a measure of dispersion, but the standard deviation can sometimes be a measure of central tendency Standard deviation is measured in the same units as the data, but the variance is not None of the above Analyze the following frequency output table for the variable 'unemp' (Ever unemployed in the last ten years). EVER UNEMPLOYED IN LAST TEN YRS Cumulative Frequency Percent ValidPercent Percent 478 YES NO Total Missing IAP NA Total If you were to ignore the missing cases, what percentage of respondents have been unemployed in the last ten years? All quantitative data is empirical, but qualitative data is not empirical. True False What is the main difference between ordinal and interval/ratio variables? The ability to rank the data in order The methods used to collect them (e.g., surveys, experiments) A consistent distance between units The research school (e.g., nomothetic vs. ideographic) Joel Best states that misplacing a is an easy mistake to make that can impact our set of mental benchmarks. data set frequency decimal none of the above Why recode a variable's values? To collapse certain values into a small number of categories To reverse the numerical order of the variable's coding To develop a migraine A and B only (honestly, not C) What tool can you use in SPSS to compare different groups with each other? COMPUTE RECODE SELECT SPLIT None of the above Use this descriptive analysis (split by 'sex') for 'mntlhlth' (the number of days of poor mental health the respondent has experienced in the past 30 days). Descriptive Statistics Respowoems sex Std Deviation DAYS OF POOR MENTAL HEALTH PAST 30 DAYS 30 3-57 5-473 Valid N (listwise) 30 4 FEMALE DAYS OF POOR MENTAL HEALTH PAST 30 DAYS Valid N (Iistwise) Which of the following statements is true? Men experienced worse mental health. Women experienced fewer days of poor mental health Women experienced worse mental health All of these could, maybe, possibly, hopefully, be true? Use this frequency output table for the variable 'degree' (highest degree obtained) to answer the following question. RS HIGHEST DEGREE Cumulative Frequency Percent Valid Percent Percent Valid LT HIGH SCHOOL 288 14.6 14.6 14.6 HIGH SCHOOL 976 49.4 49.4 64.0 JUNIOR COLLEGE 151 7.6 7.6 71.7 BACHELOR 354 17.9 17.9 89.6 GRADUATE 205 10.4 10.4 100.0 Total 1974 100.0 100.0 What percentage of respondents lack a college degree (i.e., a high school degree or less)?For the research question "What is the impact of gender upon annual income?", what type of variable is income? Constant Independent variable Dependent variable Mediator variable Moderator variable Under what conditions would you use Cronbach's alpha ( 0L )? To test the reliability of the values on multiple variables that will compose an index To lookup in the Chi2 table for the statistical significance To assess how wide the range of values will be from the mean (within ii standard deviations) None of the above Analyze the following frequency output table for the variable 'unemp' (Ever unemployed in the last ten years) EVER UNEMPLOYED IN LAST TEN YRS Cumulative Frequency Percent Valid Percent Percent Valid YES 478 24.2 35.8 35.8 NO 859 43.5 64.2 100.0 Total 1337 67.7 100.0 Missing IAP 636 32.2 NA 1 .1 Total 637 32.3 Total 1974 100.0 What percentage of the total cases are valid, non-missing cases?Which statement is NOT true about descriptive and inferential statistics? Descriptive statistics include frequencies, central tendency, dispersion Inferential statistics aim to draw conclusions about the population using the sample Descriptive statistics allow conclusions to be drawn about the population using the sample Inferential statistics include ttests, analysis of variance, Pearson's correlation, and ordinary least squares regression Which is NOT a measure of dispersion? O Range O Variance O Median O Standard deviationAccording to Best, survey results may be affected by the order in which questions are asked The way they are questions are asked and/or who is asking How the questions are worded All the above
