nominal .level .of .measurement .- .CORRECT .ANSWER-classifies .data .into
.mutually .exclusive .(non-overlapping) .categories .in .which .no .order .or .ranking
.can .be .imposed .on .the .data


nominal .- .CORRECT .ANSWER-cars .in .a .parking .lot .can .be .classified .according
.to .their .color.


nominal .- .CORRECT .ANSWER-Classifying .residents .according .to .zip .codes

ordinal .level .of .measurement .- .CORRECT .ANSWER-classifies .data .into
.categories .that .can .be .ranked; .however, .precise .differences .between .the .ranks
.do .not .exist


ordinal .- .CORRECT .ANSWER-T-shirt .size

interval .level .of .measurement .- .CORRECT .ANSWER-ranks .data, .and .precise
.differences .between .units .of .measure .do .exist; .however, .there .is .no
.meaningful .zero.


Interval .- .CORRECT .ANSWER-IQ

interval .- .CORRECT .ANSWER-Temperature .of .a .jumping .frog

ratio .level .of .measurement .- .CORRECT .ANSWER-possesses .all .the
.characteristics .of .interval .measurement, .and .there .exists .a .true .zero. .In
.addition, .true .ratios .exist .when .the .same .variable .is .measured .on .two .different
.members .of .the .population.


Ratio .- .CORRECT .ANSWER-Instagram .Followers

The .check .list .for .levels .of .organization .- .CORRECT .ANSWER-1. .Can .the .data
.values .can .be .ordered
2. .Is .there .an .interval .differences .exist .between .the .data .values
3. .Do .True .Ratios .exist .between .data .values
4. .Is .There .exists .a .significant .zero

•Qualitative .variables .- .CORRECT .ANSWER-variables .that .have .distinct
.categories .according .to .some .characteristic .or .attribute.

, •Quantitative .variables .- .CORRECT .ANSWER-variables .are .variables .that .can .be
.counted .or .measured.


•Discrete .variables .- .CORRECT .ANSWER-variables .assume .values .that .can .be
.counted


•Continuous .variables .- .CORRECT .ANSWER-can .assume .an .infinite .number .of
.values .between .any .two .specific .values. .They .are .obtained .by .measuring.


examples .of .continuous .variables .- .CORRECT .ANSWER-•Distance .a .frog .jumps
.in .a .contest
•Temperature .of .a .frog
•Weight .of .a .frog

examples .of .discrete .variables .- .CORRECT .ANSWER-•Number .of .frogs .in .a
.jumping .contest
•Number .of .basketball .goals .scored .during .a .game
•Number .of .tomato .plants .in .a .garden

examples .of .quantitative .variables .- .CORRECT .ANSWER-•Number .of .frogs
•Distance .a .frog .can .jump
•Temperature .of .a .frog

examples .of .qualitative .varibles .- .CORRECT .ANSWER-•Hair .color
•Soft .drink .brand
•Jersey .number

Eliminate .Bias .- .CORRECT .ANSWER-In .order .to .achieve .this .close
.approximation .established .sampling .techniques .are .employed. .These .sampling
.techniques .are .designed .to .eliminate .bias. .Information .obtained .from .a
.statistical .sample .is .said .to .be .biased .if .the .results .from .the .sample .are
.radically .different .from .the .results .of .a .census .of .the .population.


Random .Sample .- .CORRECT .ANSWER-a .sample .in .which .each .member .of .the
.population .has .an .equal .probability .of .being .selected.


Systematic .Sampling .- .CORRECT .ANSWER-sample .obtained .by .selecting .every
.kth .member .of .the .population .where .k .is .a .counting .number.
Where .k .is .a .counting .number.

Stratifed .Sample .- .CORRECT .ANSWER-obtained .by .dividing .the .population .into
.subgroups .or .strata .according .to .some .characteristic .relevant .to .the .study.
.Then .subjects .are .selected .from .each .subgroup.


Cluster .Sample .- .CORRECT .ANSWER-obtained .by .dividing .the .population .into
.sections .or .clusters .and .then .selecting .one .or .more .clusters .and .using .all
.members .in .the .clusters .as .members .of .the .sample.
