Step 1 Understand the Topic Being Expressed
First look at the Title.
This is about the weight of puppies.

Step 1 Understand the Topic Being Expressed
Second look at the Axes
There are twelve months listed. The weights are
listed in pounds.

Step 1 Understand the Topic Being Expressed
Third is to understand the key.
There are two dogs. Jada is indicated in green
and Winston is indicated in purple.
5
Step 2 Understand the Numerical Scale
The numbers skip by sixes however there is a line
indicating the half way point between each.

Step 2 Understand the Numerical Scale
Jadas weight for Jan. is right on the line
between 0 and 6 which means 3 lbs. However,
Winston is just above that so about 4 lbs.

Step 2 Understand the Numerical Scale
Jadas weight for Feb. is right between 6 and 12
lbs so her weight is 9 lbs. However, Winstons is
just below the line so it would be 8 lbs.

Step 2 Understand the Numerical Scale
Jadas weight for Mar. is right on the line
between 18 and 12 lbs so it would be 15 lbs.
However, Winstons weight is just above the 12
lb line so his would be 13 lbs.

Step 2 Understand the Numerical Scale
Writing the numbers can be beneficial so each
point does not need to be refigured each time.
However, if it becomes to crowded, it can cause
more problems.

Step 3 Understand the Wording of the Questions
Being Asked
In which months did Jada and Winston weigh the
same?
Key word same
Looking through the months, the two places where
the points overlap is May, October December.
11
Step 3 Understand the Wording of the Questions
Being Asked
In which months did Jada weigh more than Winston?
Key words more (Jada)
Look for the places where the green line is
higher than the purple. February, March, April
12
Step 3 Understand the Wording of the Questions
Being Asked
In which months did Winston weigh more than Jada?
Key word more (Winston)
Look where the purple points are higher than the
green. January, June, July, August, September,
November
13
Step 3 Understand the Wording of the Questions
Being Asked
What is the furthest difference in weight between
Jada and Winston? Which month?
Key words difference, furthest, month
Look for the place where the points are on the
same x-axis but are far apart on the
y-axis. August 29-24 5 lbs.

Step 4 Understand What Conclusions Can Be Drawn
from the Graph
There are many possible conclusions that can be
drawn from a piece of data.
Although Winston weighed the most in January,
Jada weighs more until May. Then Winston
primarily weighs more until December.
15
Step 4 Understand What Conclusions Can Be Drawn
from the Graph
It can be assumed that the dogs weights will
continue to stay at a slight increase. They will
not increase quickly as they did in the first six
months.
16
Step 4 Understand What Conclusions Can Be Drawn
from the Graph
It is hard to tell whether Jada or Winston will
weigh more from here considering they weigh the
same in December. It can be assumed that the two
dogs will continue to weigh close to the same.
