Question

Yes it is possible. The central tendency can be measured and create a mean, median, mode. In this case one politician could be speaking in terms of the mean average income while the other is speaking based off of the median income of the American workers. Chapter 5 4. Imagine now that in addition to the information we gathered on urban residents in Question 1 above, we also collected data on Non-urban residents and their self- evaluation of the likelihood of victimization. Calculate the index ofQualitative variation. (Note this is an ordinal variable, but the IQV is still meaningful) Likelihood of Urban Not Total Victimization Urban Very Likely 65 10 75 75 225 300 Somewhat Not Likely 80 3201 400 Total 220 555 715 Calculate the Index of Qualitative Variation.

Explanation / Answer

Likelihood of Victimization

Urban

Not Urban

Total

Percentage Distribution

Percentage Squared

Very Likely

75/775 = 9.677

93.65

Somewhat Likely

225

300

300/775 = 38.71

1498.44

Not Likely

320

400

400/775 = 51.61

2663.89

775 is the total sample size.

Pct2 = 4255.983351, K = 3 for likelihood of victimization

IQV = [3 * (1002 – 4255.983351)]/ [1002(3-1)] = 0.8616
