Use the table below to make a scatter plot of the data pairs (years since 1960, population) PLEASE HELP
2 answers:
Take 1960 as 0 then find out next year's
- 1970=10
- 1980=20
- 1990=30
- 2000=40
- 2005=45
- 2010=50
Also
Divide each population by one thousand i.e turn to decimal .
This we done to create the plot on graph easily
The graph has been attached
for the below points
- (0,9.706)
- (10,10.652)
- (20,10.798)
- (30,10.847)
- (40,11.353)
- (45,11.478)
- (50,11.576)
Answer:
When creating a scatter plot, first decide the explanatory variable and response variable.
<u>Explanatory variable</u> (independent variable) is along the x-axis.
<u>Response variable</u> (dependent variable) is along the y-axis.
The population number is dependent upon the year, therefore, draw the year along the x-axis and the population along the y-axis.
As the data values for the population start at 9706 thousand, it is sensible to begin the y-axis at 9000.
As the data values for the year start at 1960, it is sensible to begin the x-axis at 1950.
An appropriate x-axis : y-axis scale to use is 1 : 50
Plot the data points according to the given in the table.
Finally, add a title for each axis.
