What is the median of the set of numbers: 1,7,5,1,4,6,5,8,9,10,2,5,3?

1. 6

2. 3

3. 5

4. 4

The correct answer is: 5

To find the median of a set of numbers, the first step is to arrange the numbers in ascending order. For the given set of numbers—1, 7, 5, 1, 4, 6, 5, 8, 9, 10, 2, 5, 3—the ordered sequence is: 1, 1, 2, 3, 4, 5, 5, 5, 6, 7, 8, 9, 10 Next, identify the total number of values in the ordered list. In this case, there are 13 numbers, which is an odd count. The median is the number that is located in the middle position of the sorted list. To find the middle position, you can use the formula \((n + 1) / 2\), where \(n\) is the number of values. Here, \(n\) is 13, so the position is \((13 + 1) / 2 = 7\). Thus, the median is the value at the 7th position in the ordered list. Counting through the ordered numbers, the 7th value is 5
