Experiments/correleations
100
the belief that accurate knowledge can be acquire through observation
Empiricism
100
People are difficult to study because of:
Complexity, variability, reactivity
100
the action of measuring something
measurement
100
Is a technique for gathering information by unobtrusively observing people in their natural environment.
Naturalistics Observations
100
a mutual relationship or connection between 2 or more things
Correlation
200
set of principles about the appropriate relationship between ideas & evidence
scientific method
200
What do they mean when they say humans are complex to study?
The human brain is very complex
200
Operational definition is
- description of a property in concrete, measurable terms
200
The tendency to see what we expect to see, or what we want to see. When a researcher studies a certain group, they usually come to an experiment with prior knowledge and subjective feelings about the group being studied.
Observer bias
200
Positive correlation
both variables increase or decrease together
Ex: the more sleep you get, the longer you can focus on your work
300
hypothetical explanation of a natural phenomena
Theory
300
What do they mean when they say variability with humans being difficult to study?
- no 2 people ever do, think, say or feel exactly the same way under the same circumstances
300
- a device that can detect the condition to which an operational definition refers
Measure
300
an observation whose true purpose is hidden from both the observer & the person being observed
Double Blind
300
The more candy you eat now, the less dinner you’ll eat later. This is a example of what type of correlation?
negative
400
falsifiable prediction made by a theory
Hypothesis-
400
What are the two methods to study people?
- Observation Methods
- Explanation Methods

What are 3 properties of a good measurement?
Validity: refers to the extent to which a measurement and property are conceptually related.
Reliability: which is the tendency for a measure to produce the same measurement whenever it is used to measure the same thing.
Power: The ability to measure to detect the concrete conditions specific in the operational definition.

What is a frequency distribution?
A frequency distribution is an overview of all distinct values in some variable and the number of times they occur. That is, a frequency distribution tells how frequencies are distributed over values. Frequency distributions are mostly used for summarizing categorical variables.
400
The action causing something is called?
Causation
500
set of rules & techniques for observation
Empirical method
500
use one’s senses to learn about the properties of an event or an object
observation
500
Are those aspects of an observational setting that causes people to behave as they think they should.

What are the two types of variables use in a experiment?
