To model:
A line graph about grizzly bears in a park from the data given in the table.
Introduction:
Biologists follow specific steps to do research and answer queries. Scientists gather information from various experiments and collect data. After analyzing the data from an investigation, a biologist thinks if his hypothesis has been supported by the data. Often investigations are repeated many times to obtain consistent results.
Explanation of Solution
As biologists look for explanations of their data, patterns are usually noted that help to explain the data. A simple way to display the data is in a table form or on a graph.
Grizzly Bears in Park X | |
Year | Quantity |
2001 | 195 |
2002 | 190 |
2003 | 184 |
2004 | 164 |
2005 | 158 |
According to the given table, a line graph was plotted to display the number of grizzly bears in a park ‘X’ from years 2001 to 2005.
On X- axis, year was marked from 2001 to 2005 and on Y- axis, the quantity (number of bears) were marked. Points were plotted and then joined to make a line.
The line graph shows the decline in the number of bears over a period of five years.
