![]() ![]() I would suggest further research to be done under the scope of gun ownership. To sum up, we have proved that women and men from the US are not equaly likely to be afraid to walk alone at night in their neighborhood. Hence, we can conclude that there is a difference in women and men from US with respect to their fear of walking alone at night in their neighborhood.Īs we can see, the results from the hypothesis test and the confidence interval agree. # n_Female = 19117, p_hat_Female = 0.554ĭue to the p_value = < 0.0001 being less than the significance level (0.05), so re will reject the null hypotheses. # Explanatory variable: categorical (2 levels) #hypothesis test inference( y = fear, x= sex, data = gss_na, statistic = "proportion", type = "ht", null = 0,Īlternative = "twosided", method = "theoretical", success = "Yes",, order = c( "Female", "Male")) # Response variable: categorical (2 levels, success: Yes) The data from the interviews were processed according to standard NORC procedures. Block quota sampling was used in 1972, 1973, and 1974 surveys and for half of the 19 surveys. Starting in 2006 Spanish-speakers were added to the target population. The Codebook and Questionnaire for this survey can also be found in this folder and will. Each survey from 1972 to 2004 was an independently drawn sample of English-speaking persons 18 years of age or over, living in non-institutional arrangements within the United States. You can download this data and then open it directly into STATA. ![]() There are a total of 57,061 completed interviews. The data come from the General Social Surveys, interviews administered to NORC national samples using a standard questionnaire. The National Data Program for the Social Sciences is designed as a data diffusion project and a program of social indicator research. However, there might be non-response bias since there are variables in the GSS Codebook where we can notice observations called “Refused”, as well as coveniece bias since some surveys targeted English-speaking persons while others did not.Īccording to the full General Social Survey Cumulative File : Since there is no random assignment in this study, we cannot make causal conclusions.Īs this study does not employ volunteers we can also exclude the possibility of voluntary response bias. The results are generalizable to the US population above 18 years old, as this is an observational study that uses random sampling. We will investigate one question using the GSS dataset. ![]() This extract of the General Social Survey (GSS) Cumulative File 1972-2012 provides a sample of selected indicators in the GSS with the goal of providing a convenient data resource for students learning statistical reasoning using the R language. ![]()
