To find Quartile 1 (Q1) in a dataset, you can follow these steps:
1. **Order the data**: It looks like the data is already ordered: 2, 2, 10, 10, 16, 16, 24.5.
2. **Find the median (Q2)**:
The median will be the middle value of the dataset. Since there are 7 values, the median is the 4th value (10).
3. **Determine Q1**:
Q1 is the median of the lower half of the data (the values before the median). In this case, the lower half is: 2, 2, 10. The median of these three values (Q1) is the middle value, which is 2.
Therefore, Quartile 1 (Q1) is **2**.
