What are the minimum, first quartile, median, third quartile, and maximum of the data set? 18, 20, 11, 10, 8, 6, 12, 4

what are the minimum, first quartile, median, third quartile, and maximum of the data set? 60, 50, 130, 200, 180, 150, 100, 140

Let's start with the first set of data.

18, 20, 11, 10, 8, 6, 12, 4

First, you need to order the numbers from least to greatest.

4, 6, 8, 10, 11, 12, 18, 20

The minimum is the smallest data value, and the maximum is the largest.

Minimum: 4
Maximum: 20

The median is the data value in the middle of the data set or, in this case because there is an even number of values, the average of the two middle values.

Median: 10.5

The first quartile value is the median for the numbers before the median.
So find the median of 4, 6, 8, 10, the same way we did in the last step.

First quartile: 7

Finding the third quartile is exactly the same as the first, except use the values after the median. (11, 12, 18, 20)

Third quartile: 15

So, for the first problem it goes

Minimum: 4
First quartile: 7
Median: 10.5
Third quartile: 15
Maximum: 20

Now for the second problem, do the exact same thing as the first one!

60, 50, 130, 200, 180, 150, 100, 140
50, 60, 100, 130, 140, 150, 180, 200
Minimum: 50
First quartile: 80
Median: 135
Third quartile: 165
Maximum: 200

Hope this helps!!!
