Lesson 1: Mode and Median M841, M934

Lesson 4:
L1 – Finding the Mode and Median
L1 – Finding the Mode and Median
Success Criteria:
I can identify the mode in a list of numbers or words.
I can calculate the median by putting values in order.
I can work with data that includes decimals or negative numbers.
I can find the median when there is an even number of values.
I can explain what mode and median mean using examples.
Key Words:
Mode – The value that appears most often in a list.
Median – The middle value when the data is in order.
Data – A group of numbers or words that we are analysing.
Frequency – How many times a value appears.
Order – Putting numbers or items from smallest to largest (or alphabetically).
L1 – Finding the Mode and Median
The mode is the most frequent value
(it appears the most)
Count how many of each value appears
The mode is the value that appears the most
*You can have more than one mode*
Finding the Mode
The mode is the most frequent value in a dataset.
Example: Dog, Cat, Dog, Rabbit, Dog, Fish
Finding the Mode
The mode is the most frequent value
(it appears the most)
The mode is the value that appears the most
It helps if you group the words together.
Dog, Cat, Dog, Rabbit, Dog, Fish
Dog, Dog, Dog, Cat, Rabbit, Fish
Dog is the mode because it appears the most
Finding the Mode
The mode is the most frequent value
(it appears the most)
The mode is the value that appears the most
It helps if you order the values from smallest to largest.
2, 3, 4, 1, 2, 3, 5, 6, 3, 1
(order them from smallest to largest)
1, 1, 2, 2, 3, 3, 3, 4, 5, 6
(Count them to check you have the same amount of numbers)
3 is the mode because it appears the most
Finding the Mode
The mode is the most frequent value
(it appears the most)
1, 3, 3, 3, 5, 6, 6, 9, 9, 9
There are two modes here 3 and 9
Finding the Mode
The mode is the most frequent value
(it appears the most)
The mode is the value that appears the most
Work out the mode of these numbers
*It helps if you order the values from smallest to largest.*
1, 5, 6, 4, 3, 5, 3, 5, 6, 2, 10
(order them from smallest to largest)
1, 2, 3, 3, 4, 5, 5, 5, 6, 6, 10
(Count them to check you have the same amount of numbers)
5 is the mode because it appears the most
Finding the Mode
The mode is the most frequent value
(it appears the most)
The mode is the value that appears the most
Work out the mode of these numbers
*It helps if you order the values from smallest to largest.*
11, 23, 22, 14, 23, 10, 11, 16, 19
(order them from smallest to largest)
10, 11, 11, 14, 16, 19, 22, 23, 23
(Count them to check you have the same amount of numbers)
11 and 23 are the two modes because they appear the most
Finding the Mode
The mode is the most frequent value
(it appears the most)
The mode is the value that appears the most
Work out the mode of these numbers
*It helps if you order the values from smallest to largest.*
11, 23, 22, 14, 10, 12, 16, 19
(order them from smallest to largest)
10, 11, 12, 14, 16, 19, 22, 23
(Count them to check you have the same amount of numbers)
There is NO mode in this set of data!

Finding the Mode
The median is the middle number.
Put the numbers in order from the smallest to the largest.
Cover up one number on each end until you get to the middle.
2, 2, 5, 6, 7, 8, 9
Finding the Median
The median is the middle number.
The median is the value that appears in the middle…
It helps if you order the values from smallest to largest.
2, 3, 4, 1, 2, 3, 5, 6, 3, 3, 1
(order them from smallest to largest and cross them out until you reach the middle)
1, 1, 2, 2, 3, 3, 3, 3, 4, 5, 6
(Count them to check you have the same amount of numbers)
3 is the median because it appears in the middle
Finding the Median
The median is the middle value
(it appears in the middle)
The median is the value that appears in the middle
Work out the median of these numbers
*It helps if you order the values from smallest to largest.*
11, 23, 22, 14, 23, 10, 11, 16, 19
(order them from smallest to largest)
10, 11, 11, 14, 16, 19, 22, 23, 23
(Count them to check you have the same amount of numbers)
16 is the median because it appears the middle
Finding the Median
The median is the middle value
(it appears in the middle)
The median is the value that appears in the middle
Work out the median of these numbers
*It helps if you order the values from smallest to largest.*
11, 23, 22, 14, 23, 14, 10, 11, 16, 19
(order them from smallest to largest)
10, 11, 11, 14, 14, 16, 19, 22, 23, 23
(Count them to check you have the same amount of numbers)
The middle of this sequence is in-between 14 and 16 = 15
15 is the median
Finding the Median
The median is the middle value
(it appears in the middle)
The median is the value that appears in the middle
Work out the median of these numbers
*It helps if you order the values from smallest to largest.*
23, 34, 22, 24, 43, 34, 23, 34, 22, 13
(order them from smallest to largest)
13, 22, 22, 23, 23, 24, 34, 34, 34, 43
(Count them to check you have the same amount of numbers)
The middle of this sequence is in-between
23 and 24 = 23.5
23.5 is the median

Finding the Median
Show me you can find the Mode and Median
True or False: The mode must always be a number in the list.
Find the mode and median: 9, 1, 4, 2, 7, 6, 1
Can a set of data have no mode? Explain.
