I don't see the 14 percentages — could you paste the data (or upload the image)? Once I have them I can compute the IQR.
If you want to do it yourself, here are the steps for 14 values:
1. Sort the 14 numbers from smallest to largest.
2. With n = 14 (even), split into the lower half (positions 1–7) and upper half (positions 8–14).
3. Q1 is the median of positions 1–7 (the 4th value).
4. Q3 is the median of positions 8–14 (the 11th value).
5. IQR = Q3 − Q1.
Send the numbers and I'll compute the IQR and pick the matching answer.
