Data - answer collections observations, such as measurements, genders, or survey
responses. (A single data value is called a datum, a term rarely used. The term "data" is
plural, so it is correct to say "data are ." not "data is . ..")
Statistics - answer the science of planning studies and experiments; obtaining data; and
organizing, summarizing, presenting, analyzing, and interpreting those data and then
drawing conclusions based on them.
population - answeris the complete collection of all measurements or data that are being
considered. Typically, a population is the complete collection of data that we would like
to make inferences about.
census - answeris the collection of data from every member of the population
sample - answeris a subcollection of members selected from a population.
A voluntary response sample (or self-selected sample) - answer
voluntary response sample (or self-selected sample) - answeris one in which the
respondents themselves decide whether to be included.
parameter - answernumerical measurement describing some characteristic of a
population
statistic - answernumerical measurement describing some characteristic of a sample.
Quantitative (or numerical) data - answerconsist of numbers representing counts or
measurements
Categorical (or qualitative or attribute) data - answerconsist of names or labels (not
num- bers that represent counts or measurements).
Discrete data - answerresult when the data values are quantitative and the number of
values is finite, or "countable."(If there are infinitely many values, the collection of values
is countable if it is possible to count them individually, such as the number of tosses of a
coin before getting tails.)
Continuous (numerical) data - answerresult from infinitely many possible quantitative
values, where the collection of values is not countable. (That is, it is impossible to count
the individual items because at least some of them are on a continuous scale, such as
the lengths of distances from 0 cm to 12 cm.)
