Method

A method of data collection in which people are asked to provide information about themselves

ex. questionairs surveys

Advanatages: Lots of info, short time period

Disadvantages: Self-report bias or badly recalled information

A research method that examines how variables are naturally related in the real world, without any attempt by researchers to alter them

Andvantages: Rely on naturally occuring phenomina

Disadvantages: Cannot support causal relationships, directionality problem, confounds may be involved

A research method that compares participants young and old at the same time

Advantages: Faster and less expensive

Disadvantages: Confounds may be involved

A research method in which researchers make sense of perceptual and cognitive process in response to stimuli

Advantages: Simple, Less affected by bias ore reactivity

Disadvantages: Time consuming, costly, less effective in real world settings

A range of experimental techniques that make brain structures and brain activity visible

Advantages: Show brain regions involved in different tasks

Disadvantages: Show brain regions only when tasks are being performed

A research method that involves the extensive examination of one person, organization, or a few people

Advantages: Extensive data collected

Disadvantages: Very subjective

OVERALL summary of Data

Ex. How people average

A set of procedures used to make judgements whether differences actually exist between a set of numbers

is it statistically significant? or not?

A reseach method that measures the same particpants multiple times

advantages: provides info about effects of age and developmental changes

Disadvantages: Costly, long time, may loose participants

A Measure of central tendency that is the arthmetic avarage of a set of numbers

Set:1,2,3,2,1

1+2+3+2+1=9/5

9/5=1.8

The mean is 1.8

The mean is mean because it takes more math

A measure of central tendency that is the value of a set of numbers that falls exactly halfway between the lowest and highest values

Ex. Set:1,2,3,2,1

not lowest 1 not highest 1

In the middle is 3

The Median wears medium not small or large

A measure of central tendency that is the most frequent score or value in a set of number

Ex Set: 1,2,3,2,1

The mode is 2 because it occurs most

The mode is the heaviest load
