Measures of Central Tendancy Lesson 6.05

Vocabulary Review Sum – the answer to an addition problem. Addend – the numbers you added together to get the sum = 15

Definition Mean Means Average

Definition Mean – the average of a group of numbers. 2, 5, 2, 1, 5 Mean = 3

How to Find the Mean of a Group of Numbers Step 1 – Add all the numbers. 8, 10, 12, 18, 22, = 96

Step 2 – Divide the sum by the number of addends. 8, 10, 12, 18, 22, = 96 How many addends are there?

Step 2 – Divide the sum by the number of addends. 6)6) 96 sum# of addends

The mean or average of these numbers is 16. 8, 10, 12, 18, 22, 26

Definition Median is in the Middle

Definition Median – the middle number in a set of ordered numbers. 1, 3, 7, 10, 13 Median = 7

How to Find the Median in a Group of Numbers Step 1 – Arrange the numbers in order from least to greatest. 21, 18, 24, 19, 27 18, 19, 21, 24, 27

How to Find the Median in a Group of Numbers Step 2 – Find the middle number. 21, 18, 24, 19, 27 18, 19, 21, 24, 27

How to Find the Median in a Group of Numbers Step 2 – Find the middle number. 18, 19, 21, 24, 27 This is your median number.

How to Find the Median in a Group of Numbers Step 3 – If there are two middle numbers, find the mean of these two numbers. 18, 19, 21, 25, 27, 28

How to Find the Median in a Group of Numbers Step 3 – If there are two middle numbers, find the mean of these two numbers = 46 2)2) 23 median

What is the median of these numbers? 29, 8, 4, 11, , 8, 11, 19, 29

What is the median of these numbers? 53, 5, 81, 67, 25, = 120 2)2) 5, 25, 53, 67, 78, 81

Definition Mode is the most Popular

Definition Mode – the number that appears most frequently in a set of numbers. 1, 3, 7, 10, 13 Mode = 1

How to Find the Mode in a Group of Numbers Step 1 – Arrange the numbers in order from least to greatest. 21, 18, 24, 19, 18 18, 19, 21, 24

How to Find the Mode in a Group of Numbers Step 2 – Find the number that is repeated the most. 21, 18, 24, 19, 18 18, 18, 19, 21, 24

Which number is the mode? 1, 2, 2, 9, 9, 4, 9, , 2, 4, 9, 10

Definition Range is the distance Between

Definition Range – the difference between the greatest and the least value in a set of numbers. 1, 3, 7, 10, 13 Range = 12

How to Find the Range in a Group of Numbers Step 1 – Arrange the numbers in order from least to greatest. 21, 18, 24, 19, 27 18, 19, 21, 24, 27

How to Find the Range in a Group of Numbers Step 2 – Find the lowest and highest numbers. 21, 18, 24, 19, 27 18, 19, 21, 24, 27

How to Find the Range in a Group of Numbers Step 3 – Find the difference between these 2 numbers. 18, 19, 21, 24, – 18 = 9 The range is 9

What is the range? 23, 7, 9, 41, – 7 = 34 7, 9, 23, 19, 41
