Variables
Variables used in a correlational design
2 variables
Two or more subject groups are compared
Between Subjects Design
Which descriptive stat is badly affected by outliers
Mean
Assigning subjects to different conditins
Random Assignment
Behavior patters of short duration
Event
Variables used in a correlational design with regression analysis
predictor(s) and criterion(s)
Two-Group Experimental design has...
Two groups - 1 treatment and 1 control
Name 2 measurements of central tendency
mean, median, mode
Selecting who will be in the study (randomly)
Random Selection
A body of established knowledge
Science
Variables used for comparison
IV and DV
Matched (subject/group) Design
What is Discrete Data
Data based on set/fixed values (e.g., age class) - nominal or ordinal
Sampling unit
Entities on which measurements are made
Refers to the extent to which results from a study can be applied to other situations, groups, or events
External validty
Factorial design has
2+ IV and 1 DV
Has more than 2 groups, with multiple levels
Multiple Group Design
What is continuous data
Any value within a range - interval or ratio data
1st, 2nd, 3rd place are what scale of measurement
Ordinal
What is the difference between analytic and descriptive research
Descriptive seeks to describe analytic research attempts to understand through analysis
Multivariate Experimental Design has
1 IV and 2+ DV
Same subjects are tested more than once
Within Subjects Design
Descriptive stat that separates the higher half with the lower half
Median
This scale of measurement does not include zero
Ratio
Two of the three types of quantitative research questions
Descriptive, difference, relationship
Which variable can be manipulated
IV
Experimental research must have
A control group
Conclusions lead us to reject the null when it is actually true
Type I Error
This qualitative design seeks to tell a story
Narrative
Sequence data collection
