Understanding Median in a Set of Numbers

The video tutorial explains how to determine the median of a set of seven numbers. It begins by defining the median and how it is calculated for both odd and even sets of numbers. The tutorial then demonstrates ordering a given set of numbers to find the median, placing 'x' as the middle number. It concludes by evaluating which numbers from a list of choices could be the median, based on the ordered set.

What is the median in a set of numbers?

• The smallest number in the set

• The largest number in the set

• The average of all numbers in the set

• The middle number when arranged in order

How many numbers are less than the median in a set of seven numbers?

• Four

• Three

• Two

• Five

What is the first step in finding the median of a set of numbers?

• Add all the numbers together

• Multiply all the numbers

• Find the difference between the largest and smallest numbers

• Arrange the numbers in ascending order

Which number is placed in the middle when the numbers are ordered?

• 15

• 10

• 3

• 21

What range of values can the median take in this set?

• Between 4 and 18

• Between 3 and 10

• Between 10 and 15

• Between 15 and 21

Which of the following numbers could be the median?

• 14

• 5

• 8

• 16

Why can't 16 be the median in this set?

• It is not an integer

• It is less than 10

• It is greater than 15

• It is not in the set

Which number is the only correct choice for the median?

• 10

• 11

• 14

• 13
