What are Line Graphs? Video Lecture - Class 8

there are many different types of graphs
all of them are used for different
reasons but all of them make information
easier to read a line graph is used to
show how the quantity or amount of
something changes over time for example
I recorded how many apples I ate each
month for 6 months here is my data in a
tally chart
remember data is the information you
collect in an investigation at the end
of 6 months I can add my data to a line
graph to show how the number of apples I
ate
changed over time after I add labels to
the side on the bottom I can begin to
plot the data when you plot you put the
data in the right spots on the graph
like this plot that point and plot that
point there and now each point on the
graph
shows the number of apples I ate that
month to make it a line graph just
connect each point in order just like a
dot-to-dot picture this makes the data
even easier to read in this line graph
it is easy to see that I ate the
greatest number of apples during the
third month 10 apples and I ate the same
number of apples in the next two months
I know this because the line doesn't go
up or down it goes straight across and
in the final month I ate the least
number of apples only three will come
any more I ate in this month than I did
in this month all we need to do now is
add our title Apple time and done the
perfect line graph
