Given a boxplot of a data set, how can you determine the IQR, and what does it tell you about the data?
- Add the value of the lower quartile to the upper quartile
- Divide the range by 2
- Subtract the value of the lower quartile from the upper quartile
- Take the square root of the range
From a boxplot, you can determine the "Interquartile Range (IQR)" by "Subtracting the value of the lower quartile from the upper quartile". The IQR measures the range of the middle 50% of the data, which gives you a sense of the spread of the central data.
