Okay, so i see that you need help with this question and it wants to know the mean, median, mode, and range in the standard deviation for the dataset.
00:07
So the first thing that you need to do is you need to take the dataset and you need to place an order from least to greatest.
00:13
So i have 97, 106, that's a 7, 106, then 109, and 112, 117, 119, 122, 131, 131, 131.
00:46
So then, hold on, let me see.
00:53
Okay.
00:54
And so the median, if there's 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, so 1, 2, 3, 4, 5, so the median is 118, okay? the mode is 131.
01:14
The range is 131 minus 97, and that's 34.
01:22
And the mean, if you add up all of these values, so you're going to get 97 plus 106 plus 109 plus 112 plus 117 plus 119 plus 122 plus 131 plus 131 plus 131.
01:45
That is 1 ,175.
01:50
Divide that by 10 and it equals 117 .5.
01:55
So the mean is 117 .5.
01:59
Then you need to find the standard deviation...
