Population = entire group being studied
Sample = subset of the population
Example
Population: all university students
Sample: 200 students surveyed
Parameter vs Statistic
Parameter → numerical value describing population
Statistic → numerical value from sample
Examples
p = true population proportion
p̂ (p-hat) = sample proportion
Sample proportion formula
p̂ = x / n
where
x = number of successes
n = sample size
Example
