Question: For the data set 10, 20, 30, 40, 50, what is the median?

Options:

Correct Answer: 30

Solution:

Median = (30 + 40) / 2 = 35, since there are 5 numbers.

For the data set 10, 20, 30, 40, 50, what is the median?

For the data set 10, 20, 30, 40, 50, what is the median?

Step 1: Write down the data set: 10, 20, 30, 40, 50.
Step 2: Count how many numbers are in the data set. There are 5 numbers.
Step 3: Since there are 5 numbers (an odd amount), the median is the middle number.
Step 4: Find the middle number. The middle number is the 3rd number in the list, which is 30.
Step 5: Since there are 5 numbers, we can also check the two middle numbers if we had an even count. But here, we only need the 3rd number, which is 30.

Median – The median is the middle value of a data set when it is ordered from least to greatest. If there is an even number of observations, the median is the average of the two middle numbers.
Data Set Ordering – Understanding how to properly order a data set is crucial for accurately finding the median.
