(MODULE 1)
population---ans-✔✔The-entire-number-of-items-in-a-large-group
sample---ans-✔✔a-subset-of-the-population
statistical-inference---ans-✔✔the-process-of-using-data-from-a-sample-to-gain-information-
about-the-population
descriptive-statistics---ans-✔✔uses-numerical-and-graphical-methods-to-explore-data-
(e.g.,-look-for-patterns)
compiled-summary-of-the-data-analysis-in-numerical,-tabular,-or-graphical-form
histogram---ans-✔✔summary-count-of-items-in-each-category-in-a-single-variable,-in-a-
tabular-or-graphical-view
average---ans-✔✔used-as-a-measure-to-determine-a-central-value-or-location-from-the-
data-used
index-number---ans-✔✔most-widely-utilized-numerical-descriptive-statistic
--typically-a-compilation-of-several-data-sources-and-weighted-to-provide-a-consistent-
review-of-a-measured-variable
experimental-study---ans-✔✔the-researcher-manipulates-one-of-the-variables-and-tries-to-
determine-how-the-manipulation-influences-other-variables
observational-study---ans-✔✔researcher-collects-information-not-by-influencing-the-
variables-in-the-study,-but-by-simply-observing-the-variable-in-action-(active-or-passive)
data---ans-✔✔things-about-which-information-can-be-collected-and-analyzed-(people,-
numerical-information,-geographical-areas,-etc.)
data-set---ans-✔✔an-rectangular-array-of-information-that-contains-the-various-categories-
of-data-collected-for-a-specific-study
