Analyzing Data Mean Median and Mode

What is the median of the data set? Hint: re-arrange data first.

9, 7, 2, 4, 3, 5, 9, 6, 8, 0, 3, 8

• 6

• 7

• 5.5

• 9

What is the 'mean'?

• The middle number

• The difference between the largest and smallest values in a data set

• The average

• The most common response

What is the mode of the given data set?

Black, Blue, Red, Pink, Black, Black, Gray, Green, Blue, Blue, Blue, Red, Yellow, Blue, Red

• Blue and Black

• Blue

• Red

• Black

What is the mean of the given data set?

8.9, 9.4, 8.6, 9.1

• 8.5

• 8.9

• 9

• 9.1

What is the first thing you should do before you find the median or the mode?

• Start crossing numbers off

• Put numbers in order from smallest to largest

• List the numbers how they are

• Look for repeats

How do you find the mean of a data set?

• Add them all up and divide by how many numbers there are

• List in order from smallest to largest

• Add the numbers and subtract the largest number

• Find the repeated numbers

Identify the outlier of the data set:
22, 32, 26, 31, 2, 33, 27

• 32
• 31
• 2
• 22

Find the median of the data set:
18, 19, 17, 14, 20, 20, 15, 21

• 17
• 18.5
• 20
• 14

Find the mean of the data set:
34, 57, 58, 56, 21

• 45.2
• 56
• none
• 48

If my data set had an outlier that was much larger than the other numbers in my data set, what would it do to my average?

• The average would stay the same

• The average would increase

• The average would decrease

• The average wouldn't be able to be calculated
