Question
1. Americans often think of themselves as quite diverse in their political opinions, within the continuum of liberal to conservative. Let’s use GSS 2014 data to investigate the diversity of political views. The percentage distribution shown displays respondents’ self-rating of their political position. (The statistics box is not displayed; cases with no response were removed for this example.
How many categories (K) are we working with?
Calculate the sum of the squared percentages, or Pct2.
What is the IQV for this variable? Do you find it to be higher (closer to 1) or lower (closer to 0) than you might have expected for political views? Or to put it another way, did you expect that Americans would be diverse in their political views or more narrowly concentrated in certain categories?
Political Views Extremely liberal Liberal Slightly liberal Moderate Slightly conservative Conservative Extremely conservative Total Percentage (%) 41 144 126 447 163 169 43 1,133 3.6 12.7 11.1 39.5 14.4 14.9 3.8 100.0Explanation / Answer
Ans:
There are 7 categories i.e k=7
IQV = K(1002 – Pct2) / 1002(K – 1)
IQV=7*(10000-2298.70)/10000(7-1)
IQV=0.898
IQV=89.8%
it is closer to 1 and higher.
Americans would be diverse in their political views through all categories.
