Finding the Median with an Even Data Set

The video tutorial introduces the concept of the median, which is the middle number in a list of data items. It explains how to arrange data from least to greatest and find the middle value, which separates the lower half from the higher half. An example with six test scores is provided, demonstrating how to calculate the median by finding the mean of the two middle values. The tutorial concludes with the calculated median of 86.

What is the median in a data set?

• The highest number

• The lowest number

• The middle number

• The average of all numbers

How do you arrange data to find the median?

• From least to greatest

• In alphabetical order

• Randomly

• From greatest to least

If a data set has an even number of values, how is the median determined?

• By selecting any two values

• By averaging the two middle values

• By choosing the lowest value

• By choosing the highest value

In the example provided, what were the two middle values?

• 71 and 84

• 64 and 71

• 84 and 88

• 92 and 96

What is the median of the test scores: 64, 71, 84, 88, 92, 96?

• 86

• 84

• 88

• 92
