Explanation:

Step1: Recall Mode Definition

Mode is the number that appears most frequently in a data set.

Step2: Count Frequencies

• Count of 10: Let's see the data: 12,10,10,13,12,11,13,10,12,12. So 10 appears 3 times.
• Count of 11: Appears 1 time.
• Count of 12: Let's count: positions 1,5,9,10. Wait, data points: 12 (1st), 10 (2nd), 10 (3rd), 13 (4th), 12 (5th), 11 (6th), 13 (7th), 10 (8th), 12 (9th), 12 (10th). So 12 appears at 1,5,9,10? Wait no, let's list all: 12,10,10,13,12,11,13,10,12,12. So 12: 1st,5th,9th,10th? Wait no, 12 is in index 0 (if 0 - based) or 1st (1 - based): 1st,5th,9th,10th? Wait no, let's count the number of times 12 appears: 12,12,12,12? Wait the data is [12,10,10,13,12,11,13,10,12,12]. Let's count each:
• 10: positions 2,3,8 → 3 times? Wait no, 10 is at 1 (10), 2 (10), 7 (10) → 3 times.
• 12: at 0 (12),4 (12),8 (12),9 (12) → 4 times.
• 13: at 3 (13),6 (13) → 2 times.
• 11: at 5 (11) → 1 time.

So 12 appears 4 times, 10 appears 3 times, 13 appears 2 times, 11 appears 1 time. So the most frequent is 12.

Answer:

12
