Income inequality (Ratio q5/q1)
Line of best fit: Y = 77.05 –- 6.53 X
R2 = 0.44
Figure 7 Trust in relation to income inequality for selected OECD countries
Based on data from Wilkinson and Pickett (2009)
The graph in Figure 7 plots a variable Y against a variable X for 23 OECD countries
using 2005 data. Variable Y is an indicator of the level of trust in a country (measured
by the percentage of the population who agree with the statement 'Most people can be
trusted'). Variable X is a measure of income inequality (measured as the ratio of the
disposable income of the top quintile, q5, to the disposable income of the bottom
quintile, q1). Figure 7 also shows the regression equation for the line of best fit and the
value of R2 which measures the strength of association between X and Y. This
question has two parts; please answer both part (i) and part (ii).
i) Examine Figure 7 and select the statements which are correct. (Choose one or
more answers)
O R2 at around 0.44 indicates a positive association between the two variables.
O Under half of the variability of the proportion of people who agree with the trust
statement is associated with the variability of the level of income inequality.
O The higher the level of income inequality, the larger the proportion of respondents
who trust each other.
O The more respondents agree that people can be trusted, the lower the level of
income inequality in a country.
ii) Using the regression equation, calculate the change in the percentage of people
who agree with the trust statement (change in variable Y) associated with a
decrease in the inequality indicator (change in variable X) of 2. Give your answer to
two decimal places.
