WGU D771 QUANTITATIVE LITERACY
ACTUAL TEST PAPER COMPLETE
QUESTIONS AND ANSWERS FULL
SOLUTION
●● sample
Answer: a smaller, more manageable group selected from the population
to represent the larger group
●● parameter
Answer: a numerical value describing an entire population's
characteristics
●● statistic
Answer: a numerical value that describes a characteristic of a sample
●● individuals
Answer: persons or objects described by a set of data
●● variables
Answer: characteristics or measurements that we are interested in
studying
,●● quantitative variables
Answer: numerical measurements, such as age, height, weight, or
income
●● categorical variables
Answer: categories or labels, such as hair color, occupation, or favorite
type of food
●● data
Answer: actual values of the variables (raw information) that we collect
and analyze to gain insights into the phenomenon we are studying
●● random sampling
Answer: process that allows researchers to choose a random set of
individuals from a population
●● simple random sample
Answer: sample chosen from a population from which each possible
subset of the same size has an equal probability of being chosen
●● stratified sampling
, Answer: method of random sampling that involves dividing the
population into distinct subgroups called strata, based on specific
characteristics such as age, gender, or socioeconomic status
●● cluster sampling
Answer: method of random sampling that involves dividing the
population into clusters, which are naturally occurring groups like
schools, neighborhoods, or cities
●● systematic sampling
Answer: method of random sampling that involves selecting every nth
individual from a list of the population, starting from a randomly chosen
point
●● explanatory variable
Answer: variable that a researcher manipulates or observes changes in to
explain or predict the results
●● response variable
Answer: variable that represents the outcome the researcher is interested
in explaining or predicting
●● observational study
