To find the median of a data set, we need to arrange the numbers in ascending order.
The numbers in the given data set are: {13, 18, 13, 14, 13, 16, 14, 21, 13}
Arranging them in ascending order, we get: {13, 13, 13, 13, 14, 14, 16, 18, 21}
The median is the middle value in this ordered set. Since the set has an odd number of elements, the middle value is the fifth value, which is 14.
Therefore, the correct answer is 14.
To find the median of a data set, you need to arrange the numbers in ascending order and find the middle value. If there are an odd number of values, the middle value is the median. If there are an even number of values, the median is the average of the two middle values.
First, let's arrange the data set in ascending order:
{13, 13, 13, 13, 14, 14, 16, 18, 21}
Since there are 9 values in the data set, which is an odd number, the median is the middle value. In this case, the middle value is the 5th value, which is 14.
Therefore, the median of the data set is 14.
To find the median of a data set, you need to arrange the data in order from least to greatest and then find the middle value. If there is an odd number of values, the median is the middle value. If there is an even number of values, the median is the average of the two middle values.
Let's arrange the data set in order: {13, 13, 13, 13, 14, 14, 16, 18, 21}
Since there are 9 values in the data set (an odd number), the median is the middle value, which is the 5th value.
The 5th value in the ordered data set is 14.
Therefore, the median of the given data set is 14.
So the correct response is "14".
