AP Statistics Exam Review Questions Multiple-Choice Questions With Complete Solutions

How is a population measured? correct answer: a population is measured by a census. How is a sample measured? correct answer: A sample is measured using a sampling technique, of which there are several. Why do we often measure samples instead of populations? correct answer: Collecting data from an entire population is often impossible, infeasible, or beyond the capability of the resources we have available. Samples can supply good estimates of the population, and are much easier to coll...

5 number summary correct answer: The minumum value, lower quartile, median, upper quartile, and maximum value for a data set. These five values give a summary of the shape of the distribution and are used to make box plots. The five numbers that help describe the center, spread and shape of data z score correct answer: a measure of how many standard deviations you are away from the norm (average or mean) -Number of standard deviations a score is above or below the mean (positive...

Individual correct answer: Person or thing described by a data set Variable correct answer: any characteristic of an individual (usually varies from one individual to another) Categorical variable vs Quantitative variable correct answer: Categorical (qualitative) variable: places each individual into ONE of several groups (can even be a number range; e.g. age, zip code) ***ALWAYS USE BAR GRAPH FOR CATEGORICAL VARIABLES*** Quantitative variable: numerical values ***for which it makes ...
