Question: The amount spent for research and development in Chemistry Lab Inc., for the years 1998 to 2003 is shown. Which time series graphs represents the data shown?
Year199819992000200120022003
Amount ($)790082308937112711387715203



A ) Graph 2
B ) neither Graph 1 nor Graph 2
C ) Graph 1
D ) both Graph 1 and Graph 2

Steps to derive

1 A time series graph represents data that occur over a specific period of time.

2 Represent time (years) on x-axis and the amount spent for research and development on y-axis.

3 Plot the data and join the corresponding points with straight line segments as shown.


4 So, Graph 1 resembles the time series graph for the given data.



Hence the right answer is Option C
