Figure 3. Illustration of decomposition

This horizontal stacked bar chart is a stylized depiction, without any numbers attached, which illustrates our method for decomposing the increase in correct responses to a financial literacy question when the “don’t know” response option is omitted. We use this method to decompose the increase into two parts: the component due to guessing, and the residual increase.

Starting from the left side of the figure, the blue portion of the bar labelled “A” represents the share of adults who answered the question correctly when the “don’t know” option was included. The full length of the entire stacked bar, labelled below the bar by “B”, represents the share of adults who answered the question correctly when the “don’t know” option was excluded. Since the share of adults answering correctly was higher when the “don’t know” answer option was not present, B is larger than A. The overall increase in the share of adults answering correctly when “don’t know” is omitted – calculated as B less A – is represented by the section of the bar labelled above the bar as “O”.

Returning to the pieces of the bar, adjacent to A, the lighter orange portion of the bar labelled “G” represents the hypothetical share that would have answered the question correctly if everyone who had originally answered “don’t know” guessed an answer at random. We estimate G by imputing a response for the people who answered “don’t know” to the question when that answer choice was included. Next, and adjacent to “G”, the darker orange portion of the bar labelled “R” is the residual increase, which is the portion of the increase in correct responses that is above what we would expect if everyone who had originally answered “don’t know” simply guessed a response. We compute the residual increase in the share correct, R, as B less the sum of A plus G.
