Probability Distributions
A Probability Distribution lists all possible outcomes of an experiment and the
probability of each outcome. Its important to list every possible outcome in
order to meet the two conditions necessary to qualify as a probability d
Measures of Central Tendency
Descriptive statistics summarize data so we can interpret it. This week we study measures of center and
measures of variation. Together, summary statistics tell the story of the data. It is best to describe data
using several
Population and Samples
Population refers to everything or everyone that a researcher wants to study. It can be the worldwide
population, all voters in the presidential election, all women in the United States, or all bottles of wine at
