The NCS Report - Charlottesville, VA 2022 - Flipbook - Page 6
The survey datasets were analyzed using all or some of a combination of the Statistical Package for the Social Sciences (SPSS), R,
Python and Tableau. For the most part, the percentages presented in the reports represent the “percent positive.” The percent
positive is the combination of the top two most positive response options (i.e., excellent/good, very safe/somewhat safe,
essential/very important, etc.), or, in the case of resident behaviors/participation, the percent positive represents the proportion
of respondents indicating “yes” or participating in an activity at least once a month.
On many of the questions in the survey respondents may answer “don’t know.” The proportion of respondents giving this reply is
shown in the full set of responses included in the tab “Complete data”. However, these responses have been removed from the
analyses presented in the reports. In other words, the tables and graphs display the responses from respondents who had an
opinion about a specific item.
