For this problem.
00:02
We want to find the sample.
00:06
I mean the sample median and the sample mode.
00:21
And this data came from a previous problem when we are looking for the sample mean we are trying to find the average of the data.
00:35
So therefore in order to do that, we would have to add up all of the pieces of data and divide by how many there are.
00:45
And we'll use x.
00:47
Bar to represent the sample mean.
00:50
So if you were to add up all of this data we would get 98,000 256 and there happened to be 70 70 pieces of data which then the mean calculates out to be 1403 0.6 5714.
01:21
Now, in order to determine our sample median and sampled mode, it's best if our data was arranged in numerical order from smallest to largest.
01:34
So the first thing i'm going to do is i'm going to rearrange these so that they are the smallest to largest.
01:49
And you can rely on your technology to help you sort these out in order you could also create a stem and leaf plot to help you order your data.
02:04
But for median and mode it's best well for median you need it to be ordered and for mod it's easiest if it is in order.
02:27
Now mode is the pieces of data that has the greatest frequency in the list and as we go through this you're going to find our greatest frequency is just to we have some pairs, some doubles some duplicates but we do not have any numbers that repeat itself three times or four times.
02:56
And we just saw one of them right there is one of our duplicates and we're coming upon another set of duplicates.
03:27
There's another pair of duplicates.
03:30
So that's also going to be a mode because there's two of them.
03:45
We're halfway through our list and i'm specifically putting 10 in each column so that it's easy to count.
04:30
And just 20 more numbers to go.
04:37
We're going to have another pair of duplicate values...

Grateful for the explanation of how sample median, mode, and mean describe different features in the data You're the real MVP
