Scientific method requires what four attitudes?

Curiosity, Skepticism, Objectivity,and Critical Thinking


Interpreting an entire body of knowledge, not just individual studies

Collaboration


The motivation force behind scientific enquiry

Curiosity


Quistioning things and not taking things for granted

Skepticism


Seeing things as they really are

Objectivity


Thinking reflectively, productively, and evaluating evidence.

Critical Thinking


Steps of Scientific Method

Theory, Hypothesis, Conceptualize problem,Collecting research,Analyze data,Drawing conclusions,Revise research conclusions and theory


A broad idea or set of closely related ideas that attempt to explain certain observations

Theory


An idea that is arrived at logically from a theory, prediction that can be tested

Hypothesis


An objective description of how a reseach variable is going to be observed and measured

Operational Definition


Chose to study whether writing about negative emotions and the situations that caused them would reduce stress and make people healthier in the future

Pennebaker


Every member of the population has an equal chance of being selectd

Random Sampling


Observes behavior in realworld situations and makes no attempt to manipulate or control situation

Naturalistic Observation


Indepth look at a single individual

Case study


Describes the strength of the relationship between two variables of characteristics

Correlation research


Degree of relationship between two variables

Correlation coefficient


Relationship in which two factors vary in the same direction

Positive correlation


Relationship in which the two factors vary in opposite directions

Negative correlation


Carefully regulated procedure in which one or more factors believed to influence the behavior being studied are manipulated while all other factors are held constant.

Experiment


Event being manipulated by the investigator

Cause


Behavior that changes as a result of the manipulation

Effect


Variable manipulated by the researcher

Independent Variable


Variable or factor that is measured in the experiment. It can change in response to changes int the independent variable.

Dependent Variable


Group whose experience is manipulated

Experimental group


Comparison group in which all variables are held constant and no manipulation occurs

Control Group


Means that participants are assign to experimanetal and control groups by chance

Random Assignment


Mathematical procedures used to describe and summarize sets of data in a meaningful way

Descriptive statistics


Mathematical average of all scores

Mean


Score that falls exactly in the middle of the ranked distribution of scores

Median


Score that occurs most often in the set of data

Mode


Distance between the highest and lowest scores

Range


Measures how much the scores vary around the mean of the sample, or how closely the scores cluster around the mean

Standard Deviation


Mathematical methods used to draw conclusions about data that have been collected

Inferential Statistics


Means that the differences observed between two groups are so large that it is high unlikely that those differences are merely due to chance

Statistical significance


Means using an ethnic label in a superficial way

Ethnic gloss
