00:03
All right, we're given a set of data and asked which of these things is actually true.
00:07
Is the mean equal to the mode? greater than the mode, mean equals the median, mean is less than the median.
00:12
Obviously, we need to know about mean, median, and mode.
00:15
Each of them deals with the mean.
00:16
So let's talk about that one first.
00:18
For the mean, what we need to do is find the average value of this.
00:22
So it's three plus four, plus five, plus six, plus seven, plus seven, plus ten.
00:29
And then we divide by how many numbers there are.
00:31
Two, three, four, five, six, seven.
00:34
So divide that by seven.
00:36
So three plus four plus five.
00:40
Oops, i missed a plus sign in there.
00:42
Three plus four plus five plus six plus seven plus seven plus ten.
00:49
Add those together and we're going to get 42.
00:51
All right.
00:52
So we get 42 and we're going to divide that by seven.
00:55
So the mean is equal to six.
00:57
All right.
00:57
So there's a nice average for us.
00:59
Nice mean is six.
01:01
Okay, so let's talk about the mode.
01:03
The mode is the one that we see the most often.
01:06
And in this case, i have one of everything except for the seven.
01:10
So seven is going to be my mode.
01:12
It is possible to have more than one mode.
01:14
It's actually possible not to have a mode if we only had one of everything or, you know, then i wouldn't have any mode.
01:19
And if i had two sixes as well as two sevens, then the mode could be six and seven...
