Question

use Prevalent among grammer. Compare these 2 percentages as a percentage difference with the smaller as the base.

in the us in 2012 for public school students : graduating within 4 years invloved 86% of white students. 69% black student

Answer 1

% change or % difference = (Change in the value / iniitial or original value) * 100

Here we need to compare White students and Black students with Black students in the denominator

Percentage difference = (% of whote students - % of black students) / % of black students

= (86% - 69%) *100 / 69%

= 17%*100/86%

= 19.76%

Percentage % change represents the degree of chage over a time period. But here since the time period is same, we can infer that White students are 19.76% more than the black students with black students taken as the base
