726 distance learning students at long beach city college in the 2004 -2005 academic year were surveyed and asked the reasons that they took a distance learning class.
00:12
And the results are listed for you.
00:16
And we have quite a few reasons, and we have lots of percentages.
00:21
And you'll notice that those percentages do not add up to 100%.
00:25
And that's what we're going to be focusing on.
00:28
Assume that the survey allowed students to choose from the responses listed.
00:31
In the table.
00:34
Part a, why can the percents add up to over 100 percent? so the number of students is over 100? nope, has nothing to do with that.
00:41
A total of 100 percent would only represent 100 students? nope, that's not how percents work.
00:46
Since there were 726 students, the percentages could add to 726? nope.
00:52
It has to be d.
00:57
If you look at d, students were able to choose many options when answering the survey.
01:01
So this is a situation where they were told to choose as many as applied, and that's why those percentages add up to more than 100%.
01:11
Part b, since the percent's add up to over 100 percent, does that necessarily imply a mistake in the report? there's not a mistake in the report.
01:20
Again, if you look at c, there's not a mistake in the report because students were able to choose more than one answer.
01:28
So that's why those percentages add up to more than 100%...
