Purpose
determine relationships between variables OR use these relationships to make predictions
Definition
degree of relationship
determine whether, and to what degree, a relationship exists between two or more quantifiable variables
5_Experimental Research
Quasi-Experimental Research (studies that aim to evaluate interventions but that do not use randomization)
Pretest-Posttest, Nonequivalent Control Group Design ( a treatment group that is given a pretest, receives a treatment, and then is given a posttest)
Posttest-Only, Nonequivalent Control Group Design (participants in one group are exposed to a treatment, a nonequivalent group is not exposed to the treatment, and then the two groups are compared)
Experimental Designs

4_Selecting a Sample
Type in the things you like.
Selecting a nonrandom sample
quota sampling
obtained from easily accessible individuals
data gatherers are given exact characteristics and quotad of persons to be interviewed
purposive sampling
units are selected because they have characteristics that you need in your sample
convenience sampling
units are selected for inclusion in the sample because they are the easiest for the researcher to access.
Determining sample size
10-20% of population (descriptive research)
Basic random sampling techniques
Systematic sampling
a probability sampling method where researchers select members of the population at a regular interval
Cluster sampling (most useful & feasibls method) (less time and expense)
a probability sampling method in which you divide a population into clusters, such as districts or schools, and then randomly select some of these clusters as your sample
Stratified sampling
researchers divide subjects into subgroups called strata based on characteristics that they share (e.g., race, gender, educational attainment).
Simple random sampling
a type of probability sampling in which the researcher randomly selects a subset of participants from a population.
Definition
POPULATION - the group of interest to the research to which the result of the study will ideally generalise (first step in sampling)
Accessible population (realistically select from)
Target population (generalise)
SAMPLING - process of selecting a number of participants for a study in such a way that they represent the larger group from which they were selected (population).
