Question

1. What is the difference between population proportion vs sample proportion vs probability? Please explain.

Answer 1

Population proportion : A population proportion is a fraction of the population that has a certain characteristic.

Sample proportion : A population proportion is a fraction of the sample (a selected part of population) that has a certain characteristic.

Probability : Probability is a numerical description of how likely an event is to occur or how likely it is that a proposition is true.

All these three values vary between 0 to 1.

where probability is a measure of uncertainty, whereas proportion is a measure of certainty.
