The consistency of a drink machine is being tested. The machine dispenses the following ounces of water in five different trials: 12, 11, 10, 11, 14. What is the IQR of the dispensing trials?(1 point) The IQR is .
The IQR (Interquartile range) can be calculated by first arranging the data in ascending order: 10, 11, 11, 12, 14.
Next, find the median of the data set. Since there are an odd number of data points, the median is the middle number which is 11.
Now, find the first quartile (Q1) by calculating the median of the lower half of the data set: 10, 11. Q1 = 10.
Find the third quartile (Q3) by calculating the median of the upper half of the data set: 12, 14. Q3 = 13.
Finally, calculate the IQR by subtracting Q1 from Q3: IQR = Q3 - Q1 = 13 - 10 = 3.
Therefore, the IQR of the dispensing trials is 3.
