You need to know how to calculate the.
 The Mean is the average of a group of
numbers.
2, 6, 8, 4, 4, 0
 To calculate, add up the numbers in the
group:
2+6+8+4+4+0= 24
and
divide by the number of numbers in the
group
24 divided by 6 = 4.
The mean is 4


What is the mean of each data group?
Explain how you know.
2, 3, 4
2. 1, 2, 5, 4, 3
3. 5, 5, 1, 1, 0, 6
4. 10, 10, 15, 25, 40
1.

The mode is the number that occurs the
most often in a group of data.
4, 5, 2, 5, 6, 5, 1, 1
5 occurs more than any other number. 5 is the mode.

There can be only one mode. If no
number appears the ‘most’ than there is
no mode.
1, 4, 5, 2, 5, 6, 5, 1, 1
5 and 1 both occur the same number of times. There
is no mode.
You need to know how to read and
interpret graphs
 Trends:

Increasing
Decreasing

(about the same)
Explain the trends you see in this graph.
Why do you think these trends are
occurring?
