Column doesn't add up to 100% 2001-10-17
From A student:
why don't some tables I'm studying in a column add up to 100%? Example: N=338, but responses to questions asked in survey I'm studying equal of 24.3, 9.8, 43.8, DON'T add up to 100%. I'm assuming that some people surveyed out of the 338 didn't bother responding, but is there another problem related to proportion or ratio being used, but improperly labeled on graph?. Note at bottom of table says: "number in parenthesis are numbers of cases" and 338 was in parentheses. I'm lost.

1000 percent 2000-03-17
From Matt Stevenson:
If one invests $4000.00 and makes 1000% on the investment would he/she have $40,000.00?
Could one figure this by: $4000.00 * 10.0 = $40,000.00?
So is 10 times a number the same as 1000%?

Would 100 times a number be the same as 10,000%?
