• Select the smallest number

• Order the data set from least to greatest

• Identify the largest number

Why is it necessary to order a data set before finding the median?

• To calculate the sum of all numbers

• To ensure the data is in a sequence

• To identify the largest number

• 7

• 9

In a data set with an even number of elements, how do you determine the median?

• Select the smallest number

• Find the average of the two middle numbers

• Pick any two numbers and average them

• Choose the largest number

If you have two middle numbers in a data set, what is the correct method to find the median?

• Subtract the smaller number from the larger one

• Choose the larger number
