Q3. Task 1 - Graph (Solved) (Line graph)


Solution:
The line graph depicts the fluctuation in the number of people at a London underground station over the course of a day.

From an overall perspective, it is crystal clear that the busiest time of the day is in the morning. There is a sharp increase between 06:00 and 08:00, with 400 people using the station at 8 o'clock. After this the numbers drop quickly to less than 200 at 10 o'clock. Between 11 am and 3 pm the number rises, with a plateau of just under 300 people using the station.

Moving further, in the afternoon, numbers decline, with less than 100 using the station at 4 pm. There is then a rapid rise to a peak of 380 at 6pm. After 7 pm, numbers fall significantly, with only a slight increase again at 8pm, tailing off after 9 pm.

Overall, it can be inferred that the station is most crowded in the early morning and early evening periods.
