Extra Practice
Extra practice problems are available at the end of the book (Chapter 7 Extra Practice).
An inactive treatment that has no real effect on the explanatory variable
The facet of statistics dealing with using a sample to generalize (or infer) about the population
Numerical data with a mathematical context
Data that describes qualities or puts individuals into categories; also known as categorical data
The occurrence of one event has no effect on the probability of the occurrence of another event.
Very similar individuals (or even the same individual) receive two different treatments (or treatment vs. control), then the results are compared
The mean of the differences in a matched pairs design
The probability distribution of a statistic at a given sample size
The value that is calculated from a sample used to estimate an unknown population parameter
The standard deviation of a sampling distribution
The number of objects in a sample that are free to vary
An interval built around a point estimate for an unknown population parameter
The number of individuals that have a characteristic of interest divided by the total number in the population
Estimate of the common value of p1 and p2
