Mean: The mean is calculated by adding up all the given numbers and dividing the sum by the total count of numbers.
1 + 2 + 3 + 3 + 4 + 5 + 7 + 8 + 12 = 45
45 / 9 = 5
Therefore, the mean is 5.
Median: The median is the middle value when the numbers are arranged in ascending order.
In this case, arranging the given numbers in ascending order: 1, 2, 3, 3, 4, 5, 7, 8, 12
There are 9 numbers, so the middle value is the (9+1)/2 = 5th value.
The 5th value is 4.
Therefore, the median is 4.
Mode: The mode is the value that appears most frequently in the given set of numbers.
In this case, the number 3 appears twice, which is more than any other number. Hence, the mode is 3.
