If the data set is: 3, 7, 7, 19, what is the median?
Step 1: Arrange the data set in order from smallest to largest. The data set is already in order: 3, 7, 7, 19.
Step 2: Count how many numbers are in the data set. There are 4 numbers.
Step 3: Since there are 4 numbers (an even amount), find the two middle numbers. The middle numbers are the 2nd and 3rd numbers, which are both 7.
Step 4: Calculate the median by averaging the two middle numbers. Add the two middle numbers: 7 + 7 = 14.
Step 5: Divide the sum by 2 to find the average: 14 / 2 = 7.
Step 6: The median of the data set is 7.
Median – The median is the middle value of a data set when it is ordered. If there is an even number of observations, the median is the average of the two middle numbers.
