Exam Pt. 1 Research

Question 1

critical thinking:

Answer 1

examines assumptions, discerns hidden values, evaluates evidence, and assesses conclusions

thinking but critical

Question 2

theory:

Hypothesis:

Answer 2

Theory: ideas to explain the outcome of the experiment

Hypothesis: testable prediction

Question 3

Random assignment:

Random Sampling:

Answer 3

Random assignment: randomly assigned participants

Random Sampling: sample that fairly reps the population

Question 4

Types of experiments

Case study:

Replications:

Double blind procedure:

Lab experiment:

Field experiment:

Natural experiment:

Observation study:

Correlation study:

Answer 4

Case study: 1 person is studied

Replications: repeated study w/diff situation

Double blind procedure: everyone doesn’t know who is being tested on and who is just given a placebo

Lab experiment: experiment in a lab

Field experiment: Experiment in natural environment

Natural experiment: experiment no interference just observation

Observation study: look and interpret→ results

Correlation study: to see how 2+ variables effect eachother

Question 5

Experiment:

Independent variable
Vs.
Dependent variable

Experiment Group
vs.
Control group:

Answer 5

Experiment: change independent variable to see effects on dependent variable

Independent variable: manipulated

Dependent variable: not manipulated –> outcome

Experiment group: group given thing tested

Control group: group not given anything for contrast

Question 6

Effects

False consensus effect:

illusory correlation:

Placebo:

Hindsight bias:

Answer 6

False consensus effect: Believing your option is more prevalent than it is –> projecting your beliefs onto others unconsciously

illusory correlation: You see a correlation but there is none

Placebo: Effects from expectations alone

Hindsight bias: Beliving after learning the results
I KNEW IT ALL ALONG!!

Question 7

Statistics

Mean:

Median:

Mode:

Range:

Standard Deviation:

Normal curve:

Operational definition:

Correlation coefficient:

Answer 7

Mean: sum of the #’s divided by the # of #s

Medium: middle score

Mode: I’ve seen you around before, most frequent score

Range: highest - lowest

standard deviation : how individual scores differ from the mean score (total-mean)^2 = squared deviation
Sum of squared devations/ # of test subjects=standered deviation

Normal curve: bell curve

Operational definition: measuring immeasurable things (ex. emotion)

correlation coefficient: meseauring how 2+ variables impact eachother?
