To determine which term does not belong with the others, let's analyze each term:
1. **Range**: This is a measure of dispersion in a dataset that calculates the difference between the maximum and minimum values.
2. **Interquartile Range (IQR)**: This is another measure of dispersion that represents the range of the middle 50% of the data. It is the difference between the first quartile (Q1) and the third quartile (Q3).
3. **Mean**: This is a measure of central tendency, calculated by adding up all the values in a dataset and dividing by the number of values.
4. **Mean Absolute Deviation (MAD)**: This is a measure of dispersion that quantifies the average absolute difference between each data point and the mean of the dataset.
Now, comparing these terms:
- The **range** and **interquartile range (IQR)** are both measures of dispersion (how spread out the values are).
- The **mean** is a measure of central tendency (the average value of the dataset).
- The **mean absolute deviation (MAD)**, while it involves the mean, is still a measure of dispersion.
Given this analysis, the term that does not belong with the others is **mean**. It is the only measure of central tendency among a group of measures of dispersion.
