We created two groups to represent the extremes of the SES distribution. To make the groups comparable in terms of size, the lower SES group included participants who reported that their students come from predominantly Low-Income households (n = 168), whereas the higher SES group included participants whose students predominantly come from High-Income households (n = 53), or a mix of Middle and High-Income (n = 119). Since our perceived SES measure is on a discrete scale, selecting exactly the top and bottom 20% is not possible. Instead, the lower and higher income groups represent 18.44% and 18.88% of the distribution.
