The cost per serving incense for six high fiber cereals rated very good, and for nine high fiber cereals rated good are shown below.
00:09
Compute the lower quartile, the median, the upper quartile, and the intercortile range for the cereals rated very good.
00:17
So the first thing we would want to do is put those data values in order.
00:23
So it would be 16, 43, 46, 47, and 78.
00:37
So for the median, which is where i would start, we want the middle of that ordered set of data, and that's going to be right in between 46 and 47.
00:50
So that means we split that difference.
00:52
So the median is going to be 46 .5.
00:55
The lower quartile would be 43, and the upper quartile would be 63, making the intercortile range, 63 minus 43 or 20.
01:08
For the good cereal, the middle is going to be 53.
01:23
So our median is 53.
01:26
Our lower quartile is going to be halfway between 30 and 41.
01:33
So that's going to be 35 .5...
