Conducting experiments

Question 0

Diode population into subgroups (strata) and randomly sample from each strata
- ensures small groups are included

Answer 0

Stratified sampling

Question 1

Every member of a population has equal chance of being sampled

Answer 1

Simple random sampling

Question 2

First, randomly determine number of provinces, then health boards, then sample

Answer 2

Cluster sampling

Question 3

Get a sample that meets some pre-defined purpose

Answer 3

Purposive sampling

Question 4

Measure manipulated by experimenter

Answer 4

Independent variable

Question 5

Like stratified sampling, but using convenience procedures. (Strata + convenience)

Answer 5

Quota sampling

Question 6

Follows instruction of the experimenter, not a real subject - create a particular state

Answer 6

Confederate

Question 7

The extent to which the two groups differ (in a standard two group design)

Answer 7

Manipulation strength

Question 8

What the experimenter is measuring

Answer 8

Dependent variable

Question 9

Percent correct (type of measure)

Answer 9

Accuracy measure

Question 10

Response time.
Response duration.
(Type of measure)

Answer 10

Latency measures

Question 11

When performance on the DV is so low that is cannot go lower

Answer 11

Floor effect

Question 12

When the performance on the DV is so high that it cannot go higher

Answer 12

Ceiling effect

Question 13

Any characteristic that might inform the subject about the purpose of the study
Subjects tend to (consciously and unconsciously) change behavior to confirm hypothesis

Answer 13

Demand characteristics

Question 14

Experimenter can unintentionally bias the subject to behave in certain ways

Answer 14

Experimenter bias

Question 15

Experimenter does not know which condition the subject is in

Answer 15

Double blind study

Question 16

A “trail run” to try out experiment

Answer 16

Pilot study

Question 17

Can be done as part of a study or as a separate study

Check to see if manipulation is appropriate

Answer 17

Manipulation check

Question 18

A direct observation of behaviors.

Ex: self reports

Answer 18

Behavioral measures

Question 19

The independent variable might appear to have no effect on the dependent measure only because participants quickly reach maximum performance level (task is too easy)

Answer 19

Ceiling effect

Question 20

When a task is too difficult that hardly anyone performs well

Answer 20

Floor effect

Question 21

Opportunity for researcher to interact with participants to discuss ethical and educational implications of the study

Answer 21

Debriefing

Question 22

Attempt to disguise the DV by using an unobtrusive measure or by placing the measure amount of set of _____ on a questionnaire

Answer 22

Filler items

Question 23

Is a recording of a response of the body

Answer 23

Physiological measures

Question 24

Can be used to measure explicit attitudes, liking for someone, judgements about someone's personality characteristics, intended behaviors, emotional states, attributions about why someone performed well or poorly on a task, confidence in ones judgements, descriptive anchors are commonly used.

Answer 24

Self-report measure

Question 25

Participant is unaware of whether a placebo or the actual drug is being administered

Answer 25

Single blind procedure

Question 26

Stage event cents that occur during the experiment in order to manipulate the independent variable successfully

Answer 26

Staged manipulations

Question 27

Operationally define independent variables using instructions and stimulus presentations

Answer 27

Straightforward manipulations
