Complete the following frequency table.
00:04
What is the mode? what is the median? so let's look at this and complete the table first.
00:10
So we start out with neutral all the way to very unsatisfied, and we want to know what the percentage is.
00:16
To find the percentage, we're going to take each one of those numbers and divide them by 340.
00:22
So i'm going to start with 130.
00:24
I'll go 130, divide it by 340.
00:28
That'll be 38.
00:29
I'm going to just round it to the nearest percentage.
00:32
So it'll be 38%.
00:34
66 divided by 340.
00:37
That'll be 19%.
00:41
84 divided by 340.
00:43
That's going to be 25%.
00:47
29.
00:49
That would be 9%.
00:51
And then finally 31, divide about 340.
00:56
It's going to be 9 % as well.
01:01
Now if we want to know what is the cumulative frequency.
01:05
The cumulative frequency just takes that column, or this value, 130, but for the next one, we're going to take the 130 and add it to the 66.
01:17
So 130 and 66.
01:20
Other words, we want to know what is the cumulative amount for these two columns.
01:25
So that's going to be 196.
01:28
Now we want to know the cumulative amount for all three.
01:31
Columns.
01:32
So we'll add 84 to that.
01:34
So we're going to add 84...
