Questions & Step-by-Step Solutions
Find the median of the numbers: 12, 15, 10, 20, 18, 25.
Step 1: Write down the numbers: 12, 15, 10, 20, 18, 25.
Step 2: Arrange the numbers in order from smallest to largest: 10, 12, 15, 18, 20, 25.
Step 3: Count how many numbers there are. In this case, there are 6 numbers.
Step 4: Since there are 6 numbers (an even amount), find the 3rd and 4th numbers in the arranged list. The 3rd number is 15 and the 4th number is 18.
Step 5: Calculate the average of the 3rd and 4th numbers: (15 + 18) / 2.
Step 6: Perform the calculation: (15 + 18) = 33, then divide by 2 to get 33 / 2 = 16.5.
Step 7: The median of the numbers is 16.5.
Median Calculation – The median is the middle value of a data set when arranged in order. If there is an even number of values, it is the average of the two middle values.
Data Arrangement – To find the median, the data set must first be sorted in ascending order.
