, 3. Standard Deviation and Mean
Rent monthly:
Mean: $1,222.93
The standard deviation is $424.80, and the mean square footage is 1,286.03 sq. ft.
Standard deviation: 645.81 sq.ft.
Variation Coefficient | Relative Dispersion
Rent monthly:
The coefficient of variation (CV) is 0.347. The square footage is:
CV: 0.502
Conclusion:
Given its higher coefficient of variation (0.502 vs. 0.347), square footage is more dispersed than
monthly rent. This means that square footage is more variable than monthly rent.
4. Overall Trend: Amazon (AMZN): Amazon's stock rose significantly from 2016 to 2019. From
$587 in January 2016 to $2,000 in August 2018, the price rises. There is a drop around October
2018, however the trend is rising.
Google (GOOG): Google's stock has been rising, albeit less than Amazon. From $742.95 in
January 2016 to $1,337 in December 2019, the price grows. Variations occur, but the trend is

5. India's population has consistently increased from 1960 to 2017. The population rose from
449.48 million in 1960 to 1339.18 million in 2017.
China's population has steadily increased from 667.07 million in 1960 to 1386.40 million in
2017. The early 1960s see a minor drop, but the trend is up.
Population growth (1977-2017):
In 1977, India had a population of around 650.49 million. By 2017, it reached 1339.18 million, up
688.69 million.
In 1977, China had a population of around 943.46 million. By 2017, it reached 1386.40 million,
up 442.94 million.
Conclusion: India has grown faster than China over the past 40 years (1977–2017). India had a
larger absolute population gain throughout this time.
