The graph shows the students marks
in science and mathematics over three months. In which month was the lowest mark
recorded in mathematics?
On the left side of our graph,
these numbers represent the marks that the student got. The bottom information is the
month. So we have the months October,
November, December. We’ve also been given this key that
tells us the green lines represent math and the red lines represent science.
We’re looking for the lowest mark
from math, which means will be focusing on the green line. Which green line is the
shortest? That line will represent the lowest
marks. We find the shortest green
The shortest green line has a mark
of 25. But the question didn’t say what
was the lowest mark? It said in which month was the
lowest mark recorded. The shortest green line came from
the month of October.
We know this from the label of the
month where the shortest green line is from. The lowest recorded mark for math
was recorded in October.
