Sagot :
Answer:
2209
Step-by-step explanation:
The interquartile range is the 3rd quartile minus the 1st quartile. To find the quartiles, you need to find the median.
First, put the values in order.
17012, 18140, 17362, 16697, 14387 becomes
14387, 16697, 17012, 17362, 18140
The median is the value in the middle, so 17012. The first quartile is the median of the numbers to the left of the median. The numbers to the left are 14387 and 16697. Because there are an even amount of numbers, there's no middle. So the median of those values is the average (aka the sum divided by the number of values).
14387 + 16697 = 31084. Then divide that by 2 (the number of values) and you get 15542. So 15542 is the first quartile.
The 3rd quartile is the median of the values to the right. It is 17751 because 17362 and 18140 are the numbers to the right of the median. 17362 + 18140 = 35502 and 35502/2 = 17751.
The interquartile range is the 3rd quartile minus the 1st quartile
17751 - 15542 = 2209
