Question

Task 3: Fill in the following chart concerning the measures of center for the variables:

Variable	Best Measure of Center	Explain Why
Country
Infant Mortality (per 1000 live births)	Mean	The data is in numbers
Health Expenditure per capita
Obesity Rate
Average Income	Median	The data is in dollars therefore the measurement is the average.
Suicides per 100,000
Life Expectancy
Universal Health Care
Diabetes Rate
Leading Cause of Death
Hospital Beds per 100,000

Answer 1

Variable	Best Measure of Center	Explain Why
Country	Mode	as data cannot be logically order and not in numbers so median and mean cann't be used. hence, choose the most common occuring value
Infant Mortality (per 1000 live births)	Mean	The data is in numbers
Health Expenditure per capita	Mean	the data is in numbers and it will take care of outliers since it uses all the values in data
Obesity Rate	Median	the data is in the unit of rate, thus the measurement is the average.
Average Income	Median	The data is in dollars therefore the measurement is the average.
Suicides per 100,000	Mean	the data is in numbers and average will calculated using all values
Life Expectancy	median	we need 50th percentile value which is given by median
Universal Health Care	mode	categorical data so choose most common value
Diabetes Rate	median	it has a unit of rates and we need 50th percentile value which is given by median
Leading Cause of Death	mode	choose the most common occuring value i.e. most common cause
Hospital Beds per 100,000	Mean the data is in numbers and average will calculated using all values
