Okay, in this question, we want to determine the mean, median, and mode of the following numbers.
00:07
So the following numbers in this dataset are 95, 56, 70, 67, 69, and finally 81.
00:23
So there's a total of 1, 2, 3, 4, 5, 6, 7 numbers here, so 7.
00:27
And now we want to calculate the average.
00:31
So mean, also known as the average, is simply just adding up all of them so 95 plus 56 plus 70 plus 60 plus 77 plus 69 plus 81.
00:42
Total of seven numbers right here.
00:45
And that is 508, all over 7, which is the total, since we're finding the average, which is equal to 72 .57.
00:55
And that is the mean in this case.
00:56
After that, we want to calculate the median.
01:00
The way the median is calculated is by ordering these numbers right here into the least to greatest number and finding one that is in the middle.
01:10
So here we'll have the lowest one as 56, as you can see right here.

56, 60...
