Q:
# Jeremy is recording the weights, in ounces, of different rock samples in a lab. The weights of seven rocks are listed below.11, 13, 14, 6, 10, 9, 10The eighth rock that he weighed was 5 ounces. How would the interquartile range of the data be affected if Jeremy includes the weight of the eighth rock?

Accepted Solution

A:

Answer: The value of the (RIC) will increase from 4 to 5.75, that is, 44%Step-by-step explanation: To answer this question you have to know the definition of Rank well.
The range is defined as the difference between the maximum and minimum value of a series of data. Xmax - Xmin
The interleaving range (RIC) is a measure of dispersion that measures the central range of 50% of the data.
Therefore, if a low value is included, such as five, the variance of the data would be greater and, consequently, the value of the (RIC) will increase from 4 to 5.75, that is, 44%
