AND SOLUTIONS
◉ Statistics. Answer: Collection of methods for planning
experiments, obtaining data, organizing, summarizing, presenting,
analyzing, interpreting, and drawing conclusions based on data.
◉ Population. Answer: the complete collection of all measurements
or data that are being considered. typically it is the complete
collection of data that we would tend to make reference about.
◉ Census. Answer: the collection of data from every member of the
population (not really tho)
◉ Sample. Answer: a subcollection of members selected from a
population
◉ voluntary response sample. Answer: one in which the
respondents themselves decide whether to be included
◉ Parameter. Answer: a numerical measurement describing some
characteristic of a population
, ◉ statistic. Answer: a numerical measurement describing some
characteristic of a sample
◉ Quantitative data. Answer: consists of numbers representing
counts or measurements
◉ categorial data. Answer: consist of names or labels that are not
numbers representing counts or measurements
◉ discrete data. Answer: result when the data values are
quantitative and the number of values is finite or "countable"
◉ continuous data. Answer: results from infinitely many possible
quantitative values, where the collection of values is not countable
◉ nominal level of measurement. Answer: characterized by data that
consist of names, labels, or categories only, and the data cannot be
arranged in an ordering scheme (such as low to high)
Ex. Eye colors
◉ ordinal level of measurement. Answer: Opposite of nominal level
but differences (subtract) between data values either can't be
determined or are meaningless
