Question

You will look at the set of the data and determine which number is the upper work extreme with the median. What are the upper and lower quartile values?

Answer 1

The upper quartile value is 10 and the lower quartile value is 2.

Step-by-step explanation:

The upper quartile, also known as the third quartile (Q3), is the median of the upper half of the data. In this case, the median is 7, so we need to determine the upper quartile value. The upper half of the data set consists of the values: 8, 8.3, 9, 10, 10, 11.5. Since the upper half has 6 values, the middle value will be the third quartile. Therefore, the upper quartile value is 10.

The lower quartile, or first quartile (Q1), is the median of the lower half of the data. The lower half of the data set consists of the values: 1, 1, 2, 2, 4, 6, 6.8. Since the lower half has 7 values, the middle value will be the first quartile. Therefore, the lower quartile value is 2.
