1. How much snow fell in the
first 5 minutes?
ANSWER:
0.5 CM
2. Why is this data a line graph
and not a bar graph?
ANSWER:
1. BAR GRAPHS COMPARE DATA WITHIN A
GROUP AND LINE GRAPHS SHOW
CONTINUOUS DATA THAT IS SEQUENTIAL.
3. How long did it take for 3 cm
to accumulate?
POSSIBLE ANSWERS:
1. 16 MINUTES
2. 17 MINUTES
4. Based on this graph, what would
be the snow height(cm) 1 hour after
the snow began?
IT WOULD BE 6.5 CM AFTER 1 HOUR.
5. Describe the snowfall from
time 30 min through 40 min.
THE SNOWFALL HAS STOPPED FROM 30 MIN
THROUGH 40 MINUTES BECAUSE IT IS NO
LONGER ACCUMULATING.
