Step 1 :First, organize the data in ascending order: 9, 12, 12, 14, 22, 23, 25
Step 2 :To find the median, identify the middle number. Since the data set has 7 observations, which is odd, the median is the 4th number. So, \(\boxed{14}\) is the median.
Step 3 :To find the mean, add up all the numbers and then divide by the number of numbers: \((9 + 12 + 12 + 14 + 22 + 23 + 25) / 7 = 117 / 7\). So, the mean is \(\boxed{16.7}\).
Step 4 :To find the mode, identify the number that appears most frequently. In this case, the number 12 appears twice, and all other numbers appear only once. So, the mode is \(\boxed{12}\).
