4[blank_start]Continuous[blank_end]: no theoretical gap
[blank_start]Discrete[blank_end]: gaps: no decimals, basically
[blank_start]Accuracy[blank_end]: how close to the "truth" the number is -- mean
[blank_start]Precision[blank_end]: how close multiple measurements are to one another -- variance- AContinuous
- BDiscrete
- CDiscrete
- DContinuous
- EAccuracy
- FPrecision
- GPrecision
- HAccuracy
5Which of the following causes of variation are "background noise" that should be minimized before conducting an experiment?
- AMeasurement Error (ME)
- BNatural Inherent Variation
- CTreatment Effect
6[blank_start]Treatment effect[blank_end]: variation due to manipulation on purpose to test outcome
[blank_start]Measurement Error (ME)[blank_end]: variation due to limitation, peiople, place, instruments
[blank_start]Natural Inherent Variation[blank_end]: variation due to genetics, biology, environmental history- ATreatment effect
- BStandard Error (SE)
- CMeasurement Error (ME)
- DStandard Deviation
- ENatural Inherent Variation
7How do you reduce Measurement Error (ME) and Natural Inherent Varation (NIV)?
- AME: Practice, Maintain Instrument, Stable Environment
- BNIV: Selection of Individuals, Acclimate Individuals
- CME: Selection of Individuals, Acclimate Individuls
- DNIV: Practice, Maintain Instrument, Stable Environment
8How do you deal with ME and NIV in an experimental design?
- AME: take multiple measurements
- BNIV: increase sample size use blocking
- CME: increase sample size use blocking
- DNIV: take multiple measurements
9Which of the following creates the most accurate result estimation?
- ARandom Selection with Replacement
- BRandom Selection w/o Replacement
- CHaphazard Selection
10Measurement Units are the objects manipulated in the experiment
- ATrue
- BFalse
11[blank_start]df between[blank_end]: related to number of treatments in an experiment
[blank_start]df within (error)[blank_end]: related to the number of EU in an experiment
[blank_start]MS between[blank_end]: variance beteen treatments; includes differences caused by the [blank_start]treatment, EU, and MU[blank_end]
[blank_start]MS within (error)[blank_end]: variance within treatments; includes differences caused by the [blank_start]EU and MU[blank_end]
[blank_start]F[blank_end]: should test for treatment effect- AF
- BMS within (error)
- CMS between
- Ddf between
- Edf within (error)
- FEU and MU
- Gtreatment, EU, and MU
12What are the main problems using MU for EU in testing treatment effects?
- Aincorrectly inflates n, which generates wrong df for within (error) term
- Bgenerates the wrong number for MS within (error) term, meaning the F statistic is wrong
- CMUs inside EUs are not independent, which is not always a problem depending on the analysis as long as EUs are used to test for the treatment effect
- DTrick question: MUs should always be used in testing treatment effects
- Egenerates the wrong number for the mean, distorting all of the following calculations
